Single Review, online available, Very Short, Date 09/21/2011Lenovo ThinkPad T420 ReviewSource Student Buying Guide versionThe ThinkPad T420 or T420i is a great option as a college laptop. It has the battery life, usability and build quality it takes to get work done around campus. The option of configuring either a budget level laptop of around $800 or high-end laptop configuration of $1,400+ is great and allows you to design a laptop that fits your needs, but still get the same build and design quality no matter what you include. I like the fact the option for a higher resolution screen is present, for those of us that find we can do work more efficiently using two windows open at once on the screen you will appreciate the 1600 x 900 resolution screen. Overall a thumbs up on buying the T420 that is a worth successor to the previous ThinkPad T410 and improves on an already great line of laptops.

In addition to desktops and notebooks, the company also produces monitors, projectors, servers, etc. In 2011, Lenovo acquired the majority of Medion AG, a European computer hardware manufacturer. In 2014, Lenovo took over Motorola Mobility, which gave them a boost in the smartphone market. From 2014 to 2016 Lenovo's market share in the global notebook market was 20-21%, ranking second behind HP. However, the distance decreased gradually.

Finally Review of the Lenovo ThinkPad T420, cpu and gaming test.Cheap Video Games at: ThinkPad T420 full specs:http

Uma constante invariável. O design experimentado e testado do Thinkpad praticamente se manteve intacto no exterior. Mas a partir de agora, o novo hardware Sandy Bridge faz seu trabalho dentro do T420. Além disso, o compacto portátil de escritório ostenta uma excelente configuração de comunicações para o campo Lenovo sem dúvida criou um nome por si mesma no campo empresarial com os portáteis Thinkpad. A série T deseja "oferecer os melhores serviços de segurança, comodidade, serviços e suporte" se acordo com o web site da Lenovo, e, portanto, distingue-se do topo da série W significantemente mais forte. Em compensação, a série X pontua com uma mobilidade mais ampla. O nosso equipamento de teste é o de 14 polegadas da série T, chamado T420. Adjacentemente, o modelo de 15 polegadas, T520, também é oferecido e está em análise ao mesmo tempo. Essencialmente os portáteis Tx20 somente se diferenciam dos modelos anteriores, chamados T410 e T510, por uma atualização no hardware para os novos processadores Sandy Bridge. O nome completo do equipamento é T420 4236-NGG. Dentro dele um CPU Intel Core i7 2620M faz o seu trabalho. O chip gráfico incorporado, Intel HD Graphics 3000, esta exclusivamente disponível para a saída de vídeo em nosso modelo de teste. Esta configuração é suportada por uma memória de quatro gigabytes DDR3 e um veloz disco rígido de 500 GB com uma velocidade de rotação de 7200 rpm. Além de vários processadores Core i, o T420 também está disponível com uma placa de vídeo dedicada NVIDIA NVS 4200M e tecnologia Optimus – pelo menos nos EUA. Conseqüentemente, a valoração das partes contingentes do desempenho depende da configuração real e pode não necessariamente ser aplicado a outros modelos. O Thinkpad T420 pode ser praticamente visto como um oponente imediato do Latitude E6420 basicamente configurável se forma similar. Enquanto a Dell optou por um design completamente novo, a Lenovo contrariamente continua com o design experimentado e testado para o Thinkpad T420. Vamos demonstrar até que grau se diferenciam ambos os portáteis ou 15 polegadas, o visual foi mantidoA primeira vista, o T420 não parece de diferenciar muito do T410. Mas isto é enganoso. Por uma coisa, a diagonal da tela se reduziu de 14,1 polegadas para 14 polegadas. O mesmo se aplica para a altura e largura do portátil, sendo que a profundidade interessantemente aumentou um pouco. As medições para comparação 30,5x340,5x233mm para o T420 e 32x336x239 para o T410. Embora muitas poucas mudanças tenham sido feitas na conectividade, a Lenovo permanece com o design leve de concha. Nenhuma modificação pode ser encontrada nas opções de cores ou materiais. O case quase completamente preto foi feito de plástico. A sensação táctil corresponde à seleção dos materiais. No entanto, as superfícies mate e levemente ásperas nãos são desagradáveis. A estabilidade do case é basicamente satisfatória. Mas ainda mostra as mesmas deficiências conhecidas do T400. Portanto, na área do compartimento Ultra Bay e na coberta plástica sobre o teclado. O case pode ceder um pouco e ranger sob pressão seletiva. Os componentes da tela resistem bem os nossos testes de rigidez e pressão. Quando o portátil é levantado pelas bordas não se deforma quase nada. As dobradiças primeiro cedem antes que surjam distorções na imagem sob pressão seletiva. Em compensação, o marco da tela cede evidentemente quando é aplicada pressão e permite que os desvios da imagem se tornem visíveis. Gostamos das dobradiças metálicas que dificilmente se balançam depois de ajustar o ângulo de apertura. Surpreendentemente, elas não suportam muito bem as condições de trabalho turbulentas viagem em trem. Como são suaves e a unidade base é suficientemente pesada, é possível abrir e fechar o portátil com uma mão. O ângulo máximo de apertura de um pouco mais de 100 graus não causa restrição alguma. Adicionalmente ao design de concha, o gancho ramshorn contribui para o transporte seguro. Ele mantém o equipamento seguramente fechado e pode ser aberto facilmente com o botão deslizante na frente. Vamos começar com um tour ao redor do próprio equipamento. Notamos que o posicionamento favorece um pouco aos usuários destros. Dependendo da utilização de entradas individuais, alguns cabos podem encher o lado esquerdo, o qual poderia obstruir consideravelmente a área de trabalho à esquerda do portátil. Duas das cinco entradas USB o entrada para tela, a VGA e a RJ45 estão na área central esquerda. Em oposição, a Lenovo tomou cuidado no posicionamento de entradas que potencialmente estarão ocupadas de forma permanente, como as outras duas entradas USB e a entrada combinada eSATA/USB, na área posterior direita. Adicionalmente, a direita aloja, da frente para trás, um conector de áudio combinado de 3,5mm, o drive ótico em um compartimento Ultra Bay, um leitor de cartões 4em1 que suporta SD, MM, SDHC, SDXC, e uma entrada ExpressCard34 port. A parte posterior é completada por uma entrada USB energizada e um modem RJ11. O adaptador de força também é conectado na parte posterior do case. Infelizmente, a Lenovo, como a Dell no seu E6420, esqueceu-se de instalar uma entrada USB no curso de atualização. Embora a interface eSATA também ofereça um índice de transferência de dados mais alto que o de um USB cada vez mais memórias de armazenamento mássico estão sendo oferecidas com entradas USB e o eSATA esta desaparecendo pouco a pouco do mercado. Em comparação com a concorrência, também notamos que a Dell recorre à utilização de uma entrada HDMI no E6420 e por isso aceita as restrições pertinentes. Em oposição, a Lenovo permanece decidida na instalação de uma entrada para tela diretamente no equipamento. Comparado com o seu predecessor, o T410, quase nada significante foi modificado. Apenas uma interface USB energizada foi adicionada. Além disso, a disposição das interfaces foi corrigida, mas não realmente melhorada. Portanto, se você encontrar cabos na área de trabalho do lado do portátil, ou se você não deseja voltar a conectar todos os cabos após o uso móvel, você pode fazer uso de uma estação docking. A entrada docking está, como é habitual, na parte inferior do portátil. Por falar em estações docking – continua sendo interessante ver quais soluções docking conseguirão chegar a te a Europa. Atualmente, dois modelo estão disponíveis para oT420 nos EUA O ThinkPad Mini Dock Plus Series 3 US/Canada/LA -> infromação do fabricante por cerca de 250 Dólares Americanos. Ele permite conectar três monitores externos adicionais adicionalmente à tela instalada. Em segundo lugar, a entrada ThinkPad Port Replicator Series 3 -> informação do fabricante por cerca de 280 Frontal Botão deslizante para abrir Lado Esquedo Ventilador, VGA, RJ45 LAN, dois USB compartimento para disco rígido Lado Posterior RJ11, USB energizado, bateria, conector de força, ventilador Lado Direito conector de áudio combinado, drive ótico, ExpressCard34, Leitor de Cartões 4em1, USB entrada combinada USB/eSATA, compartimento de segurança KensingtonComunicação Como o T410, o nosso T420 de teste ganha pontos uma extensa configuração de comunicação. Tudo o que é útil e está disponível está instalado. Um módulo Bluetooth versão é opcional, e está instalado no nosso equipamento de teste. Este permite a troca de dados com equipamentos pequenos portáveis, como PDAs ou telefones celulares. Também opcional é um módulo de banda larga móvel F5521gw Mobile Broadband também instalado em nosso Thinkpad. O compartimento SIM equivalente está localizado no compartimento da bateria. Os cabos da antena estão instalados para que assim um módulo UMTS/HSPA possa ser instalado depois. Com respeito ao WLAN, são dadas várias opções. Um módulo Centrino Ultimate-N 6300 AGN agn da Intel está no equipamento de teste. O portátil pode ser conectado às redes Ethernet através da conexão de rede Intel 82579 LM Gigabyte. As videoconferências não são um problema com a câmera opcional de 720p HD es esta configuração. Segurança Adicionalmente ao obrigatório Seguro Kensington Lock, o T420 também tem um leitor de impressões digitais, entre outras coisas. Um teclado a prova de derrames evita a perda de dados no caso de um acidente com líquidos. Suprimentos Além da parafernália necessária, como o adaptador de força e bateria, apenas um pouco de informação impressa está incluída no conteúdo da entrega. O usuário deve criar DVDs de recuperação para o pré-instalado Windows Professional 64bit imediatamente depois da compra. Porém, isto não é um problema com a conveniente ferramenta ThinkVantage. Garantia A garantia padrão para a gama T é de três anos na Europa. A garantia básica inclui apenas um ano de serviço “bring-in” nos EUA. Várias extensões da garantia podem ser adquiridas Nem o design nem a disposição foram modificadas em comparação com o T410. Aparte das teclas STRG e FN trocadas, estamos lidando com uma disposição padrão com agrupações de teclas claramente posicionadas. A tecla blue ThinkVantage mais uma vez é a tecla adicional mais chamativa. Ela abre as ferramentas ThinkVantage, respectivamente um processo de recuperação pode ser iniciado durante o booting. À esquerda dela está um botão de mute para os alto falantes e microfone e um controle giratório para o volume. A iluminação do teclado está integrada no marco superior da tela, como estava no T410. Esta pode ser ligada /desligada com as teclas FN+PGUP. A luz pode ajudá-lo a encontras o seu caminho nos dispositivos de entrada na escuridão, mas em nossa opinião não se compara com teclado com iluminação posterior. Os digitadores produtivos irão achar o teclado do Thinkpad muito agradável devido a suas qualidades mecânicas, deslocamento bem dosado da tecla e claro ponto de pressão. Adicionalmente, as teclas côncavas aumentam o conforto da digitação. Infelizmente, o teclado torna-se muito barulhento especialmente durante a digitação enérgica. No entanto, a digitação não é um problema desde o início. Touchpad e Trackpoint As semelhanças com o T410 são impressionantes aqui. O touchpad e trackpoint podem ser independentemente desabilitados e habilitados através do F8+FN. O touchpad comprova ter uma agradável superfície áspera com boas propriedades de deslizamento. O controle do cursor do mouse novamente é preciso sem problemas e os recursos multi-touch respondem conforme o esperado. Além disso, o rolamento através dos campos de rolamento na borda do touchpad também é possível. As bordas do touchpad dificilmente podem ser distinguidas do case que o rodeia devido a uma junta simples. Os botões correspondentes precisam de um pouco de tempo de adaptação, pois estão na borda angular. Eles são lisos, respondem bem sobre toda sua superfície e o clique não é muito barulhento. Alternativamente, também há um trackpoint vermelho. Ele permite uma navegação precisa do cursor do mouse. Os botões correspondentes são suficientemente silenciosos. Também não há reclamos com respeito à lugar do formato 1610 como é no T410, agora é usado um formato 169. A diagonal da tela foi marginalmente reduzida de 14,1 para 14 polegadas. Em compensação, a resolução foi aumentada de 1440x900 pixels para 1600x900 pixels. Com isso, agora há tantos pixels na altura total como no modelo anterior. No entanto, O dispositivo de teste ganhou um pouco de largura. Como é de se esperar de um equipamento empresarial, a superfície da tela foi revestida com um filme anti-reflexos. Com isso o equipamento não apenas atende os requerimento de telas de estações de trabalho, mas também é mais adequado para o trabalho em T420 tem melhorado no geral em comparação com o T410 em termos de avaliações. É mais brilhante e iluminado mais uniformemente. Apenas o valor de escuridão é levemente mais baixo que o do modelo anterior. Apesar de tudo, o melhor brilho resulta em um contraste um pouco mais alto. Em contraste, o E6420 pontua com um brilho máximo significantemente mais alto de 320 cd/m2 e ainda 277,7 cd/m2 em média. Em compensação, o portátil da Dell deve admitir a clara derrota no campo do valor de escuridão e contraste. 197cd/m²190cd/m²214cd/m²213cd/m²223cd/m²221cd/m²210cd/m²198cd/m²194cd/m² Distribuição do brilhoLEN40A1Gossen Mavo-MonitorMáximo 223 cd/m² Nits Médio cd/m²iluminação 85 %Contraste 1621 Preto cd/m² AdobeRGB 1998 Argyll 3D61% sRGB Argyll 3D Display P3 Argyll 3DComo pode ver nas fotos de comparação, que foram feitas com vários perfis de cores ICC, o T420 não foi feito para a edição profissional de imagens. O Adobe RGB e sRGB não são cobertos. Por isso está na mesma liga do Dell E6420 com o mesmo tamanho da tela e resolução. As diferenças em vista da reprodução de cores se tornaram visíveis em comparação com telas com qualidade especialmente alta. Elas podem ser encontradas, por exemplo, no Apple MacBook Pro 13 ou no Dell XPS 15. Inclusive o irmão mais velho do T420, o T520, ganha mais pontos aqui. Com uma superfície anti-refletiva e um brilho médio de mais de 200 cd/m2, que também está disponível no modo de bateria, o modelo de teste é muito adequado para o uso em exteriores. O conteúdo da tela permanece suficientemente legível inclusive sob a luz direta do ultimo ponto que vimos para avaliar a tela é a sua estabilidade dos ângulos de visão. Resulta satisfatório horizontalmente e a imagem pode ser reconhecida se problemas inclusive em ângulos muito estreitos. Como é habitual na maioria dos portáteis, os ângulos de visão no plano vertical são consideravelmente menores no T420. Conseqüentemente, você pode ter certeza que precisará ajustar o ângulo de visão freqüentemente para garantir uma imagem legível, especialmente durante o uso em exteriores. Quando muita gente esteja olhando para a tela ao mesmo tempo, seus olhos devem estar quase na mesma de Visão Lenovo Thinkpad T420 4236-NGGA série Thinkpad T420 de portáteis baseiam-se no chipset QM57 Express. Atualmente vários modelos com Core i5 ou i7 da segunda geração estão sendo oferecidos. Para ser exato, o nosso modelo de teste foi equipado com um CPU Intel Core i7 2620M Sandy Bridge. Atualmente é o processador dual core mais veloz da família Sandy Bridge que foi introduzido no início de 2011. Pode processar até quatro threads ao mesmo tempo graças ao Hyper Threading. A tecnologia Turbo Boost permite que os de um núcleo possam acelerar dinamicamente de 2,7 GHz até 3,4 GHz, dependendo da carga e capacidade de esfriamento. Em comparação com os processadores Arrandale, a função turbo foi melhorada entre outras do Sistema Lenovo Thinkpad T420 4236-NGG O chip Intel HD Graphics 3000 com suporte para DirectX 10 incorporado diretamente no processador está disponível para a saída de vídeo no nosso equipamento de teste. Por isso, o desempenho gráfico está quase no mesmo nível de uma placa Nvidia Geforce 310M de gama baixa. Como o Latitude E6420, modelos com uma NVIDIA NVS 4200M e Tecnologia Optimus estão listados nos EUA. Nosso T420 tem uma RAM de quatro gigabytes DDR3 disponíveis para a memória principal. Eles estão em um só chip, inacessível para o usuário. Apenas o segundo, ainda desocupado compartimento é acessível através da coberta de manutenção. O usuário pode fazer uma atualização facilmente. Devido ao sistema operacional Windows 7 Professional de 64bit, os quatro gigabytes da memória principal podem ser aproveitados eficientemente, ao contrário de uma versão de 32 bit, e não há nada que impeça uma atualização da RAM.

Os índices de desempenho estão de acordo com as expectativas nesta configuração de hardware. O nosso candidato de teste atingiu uma pontuação total de 7845 pontos, o qual deve-se especialmente à sua alta sub-pontuação de comunicações, no teste PCMark Vantage para avaliar o desempenho geral. Por isso, esta inclusive no mesmo nível de máquinas para jogos mais potentes, como oAsus G73SW GeForce GTX 460M, Intel Core i7 2630QM, em termos de desempenho de do Desempenho Gráfico O equipamento de teste ainda pode se enfrentar com máquinas para jogos como o Asus G73SW em termos de desempenho de aplicativos. No entanto, em vista do hardware gráfico, não tem chance alguma no desempenho 3D como esperávamos desde o início. Isso é confirmado pelos resultados no Teste Cinebench Shading e os vários benchmarks 3DMark. Infelizmente, os resultados do teste estão por embaixo de aqueles que seriam os esperados para uma HD Graphics 3000. No entanto, como as medições de energia sempre se mantêm por abaixo do par, temos que lidar com um equipamento defeituoso. Outro indicativo disto é que a detecção de dispositivos da Ferramenta ThinkVantage falha regularmente. Para excluir um problema nas configurações verificamos o BIOS e as configurações de energia no Windows 7. Vamos tentar conseguir um equipamento de substituição para uma análise de atualização. Vamos consultar os nossos testes detalhados do chip Intel HD Graphics 3000 e da folha de especificações da HD Graphics 3000 para mais informação. 3DMark 05 Standard 6131 pontos3DMark 06 Standard Score 3381 pontos3DMark Vantage P Result 1696 pontosAjuda Velocidade de Transferência Mínima MB/s Velocidade de Transferência Máxima 102 MB/s Velocidade de Transferência Média MB/s Índice de Explosão MB/s O disco rígido do nosso equipamento de teste é um ST9500420AS da Seagate. Ele tem uma capacidade bruta de 500 GBs, onde uma parte é usada como uma partição de recuperação oculta. Ele alcança resultados coerentes nos testes HDTune e CrystalDiskMark com uma velocidade de revoluções de 7200 rpm. Um gravador de DVD também está disponível como outro equipamento de armazenamento massivo. Para ser precisos, é um Optiarc DVD RW do Sistema O T420 sempre permanece suficientemente silencioso sem importar a carga. O ruído do sistema e de constantes 32,2 dBA com carga leve. O disco rígido é um pouco mais barulhento com 32,5 dBA durante o acesso. O portátil de teste atinge apenas um nível de ruído máximo de 35,2 dBA durante o nosso teste de estresse GPU e CPU com carga total. Por isso o ruído operacional sempre mantém um nível aceitável. No entanto, as avaliações do consumo de energia 28W máx. indicam que o processador não aproveita sua máxima capacidade possível mesmo durante o teste de estresse. Monitorando a freqüência do processador com a ferramenta CPUZ registramos a freqüência predefinida de 2,7 GHz para o CPU no teste de estresse. Isto significa que não há overclocking em nenhum dos núcleos e no GPU durante a carga. O CPU funciona com uma freqüência de 3,19 GHz quando apenas o Prime95 está ativado. Quando o Furmark é adicionado, o sistema reduz para 2,7 GHz. Também conseguimos registrar um máximo de 3,19 GHz no Cinebench R10 Single Core rendering. O medidor de freqüência permanece no mesmo nível no multi core rendering. Conseqüentemente a freqüência máxima possível do i7-2620M de 3,4 GHz não é aproveitada em nenhum estado testado. Apesar de tudo, os resultados de benchmark que são determinados no Cinebench R10 se mantêm dentro da faixa esperada dos CPUs i7-2620M e não demonstram irregularidades com respeito a possíveis afogamentos.

As temperaturas internas do núcleo do processador dual core Core i7 2620M pulam até um máximo de 85 graus Celsius.

Alto falantes A qualidade dos alto falantes não pretende ser valorada como alta em um portátil de escritório para uso profissional como em, por exemplo, um portátil multimídia notebook. De fato, ambos os alto falantes estéreo, à esquerda e direita do teclado, são basicamente adequados para a voz. Não é possível desfrutar da música devido ao com diminuto, pobre em baixos e pesado nos agudos. Fones de alta qualidade, conectados ao conector combinado de áudio de 3,5 mm, podem remediar isto. O sinal é transmitido claramente, sem distorções e sem estática no teste apenas teste de áudio, sem medições.O nosso modelo de teste está no começo com uma bateria de lítio íon de 6 células de 57 Wh neste teste. Uma possibilidade de estender a duração da bateria é fazer o pedido da bateria de 9 células. A outra é o acoplamento de uma bateria de 9 células. De acordo com as especificações do fabricante, é possível uma duração máxima total da bateria de até 30 horas. Em qualquer caso, uma máxima duração de bateria de "apenas" sete horas e meia é possível com a matéria que temos em mãos. O teste BatteryEater's Reader determinou esta duração com brilho mínimo, com o módulo wireless desabilitado e em modo de economia de energia. Este índice é pouco realista para o uso prático devido ao mínimo é inútil brilho mínimo. Nós executamos o teste WLAN som um brilho utilizável, ou seja, desde o nível 12 a 15. Podemos fazer pesquisas na internet para até seis horas, também em perfis de economia de energia, neste cenário de baixa carga sem vídeos flash. A reprodução de um filme acaba depois de um pouco mais de três horas no teste de DVD. Foi executado com brilho máximo e módulos wireless desabilitados, bem como em modo "Vídeo". A duração da bateria cai em picada com aplicativos intensos 3D, brilho máximo, módulos wireless habilitados e modo de desempenho máximo. O teste BatteryEater Classic simula um cálculo OpenGL e registra uma mínima duração de bateria de apenas cerca de uma de Execução da Bateria Ocioso sem WLAN, min brilho 7h 28min Navegar com WLAN 5h 59min Carga máximo brilho 1h 06min O Latitude E6420 claramente tem a liderança nos testes de bateria devido a sua maior bateria de 9 células. As durações de bateria do nosso equipamento são, apesar de tudo, extraordinárias em relação com a capacidade da bateria. Isso se deve especialmente devido ao baixo consumo de energia. É um pouco mais baixo que o do E6420 com 6,8 para 11,5 watts no modo inativo. Surpreendentemente, o máximo consumo de energia não foi tão alto quanto esperávamos no teste de estresse 100% de carga do CPU e GPU. Somente o CPU comprova ter uma perda máxima de energia de 35 watts. No entanto, nossos medidores apenas registraram 28,6 watts para o sistema inteiro. Por isso, verificamos as configurações no PowerManagement da Lenovo em Windows 7 e as configurações do BIOS. Mas não encontramos nada em lugar algum. As configurações para o funcionamento conectado na tomada estão estabelecidas claramente em "Desempenho Máximo" no BIOS. O T420 também está disponível com uma placa de vídeo NVIDIA NVS 4200M dedicada nos EUA. Por isso a Tecnologia Optimus é usada para manter baixo o consumo de energia durante a carga baixa. Como o nosso equipamento de teste E6420 está equipado com a placa de vídeo NVIDIA NVS 4200M e opção Optimus, nosso T420 tem uma evidente vantagem no consumo de energia durante cenários de Thinkpad T420Além do aumento do desempenho esperado devido à nova geração de processadores, muitas coisas experimentadas e testadas foram mantidas. Isto também aplica-se tanto para o case como para as convenientes ferramentas pré-instaladas ThinkVantage. Pequenas modificações e upgrades podem ser encontrados na conectividade. Apesar de tudo, o usuário ainda tem que viver sem o USB Em compensação, uma entrada eSATA/USB foi instalada. A configuração de comunicações do portátil de teste é extensa. Todas as opções disponíveis são aproveitadas módulo de banda larga, Bluetooth versão WLAN com suporte para padrão n e gigabit Ethernet. Gostamos da tela de 14 polegadas que é marginalmente menor que a do T410 diagonal da tela. A disposição do desktop foi mantida, respectivamente inclusive foi melhorada em largura devido a uma resolução de 1600x900. Não há nada que impeça o uso móvel com a tela mate e o bom brilho. No entanto, o T420 apenas oferece valores padrão em termos de reprodução de cores. De acordo com o fabricante, supostamente é possível atingir uma duração de bateria de até 30 horas com a bateria de 9 células do sistema e adicionalmente, com a bateria acoplada de 9 células. Atingimos uma duração de bateria plausível de até 6 horas com nossa bateria de 6 células com uma capacidade de 57 Wh Teste WLAN. O T420 basicamente foi criado para clientes empresários que procuram por um sólido portátil de escritório com um bom desempenho de aplicativos e, apesar de tudo, boas qualidades móveis. Um leve aumento do desempenho em aplicativos 3D pode ser esperado nas configurações com uma placa de vídeo Nvidia NVS 4200M dedicada, que também suporta DirectX 11, listados nos EUA. No entanto, o nosso portátil de teste não sofrerá uma mutação para uma estação de trabalho co gráficos mais potentes mesmo com esta solução gráfica. Por cortesia da...

SELAMAT DATANG di hargano.com, Semoga Rezeki Kita nambah 1000x lipat ^_^ Jual Laptop Second Lenovo Thinkpad T420 [ Lihat Gambar Lebih Besar Gan] Rp 2.000.000: Lenovo Thinkpad T420 An invariable constant. The tried and tested Thinkpad design has practically remained untouched on the outside. But from now on, the new Sandy Bridge hardware does its job inside the T420. Moreover, the compact office laptop boasts with an excellent communication configuration for the professional has doubtlessly made a name for itself in the business field with the Thinkpad notebooks. The T-series wants to "offer the best security, manageability, services and support" according to Lenovo's homepage, and thus sets itself apart from the top of the significantly stronger W-series. In return, the X-series scores with a greater mobility. Our test device is the 14 incher from the T-series, called T420. Adjacently, the 15 inch model, T520, is also offered and in review at the same time. Essentially, the Tx20 laptops only differ from the previous models, called T410 and T510, by a hardware refresh to the new Sandy Bridge processors. The test device's full name is T420 4236-NGG. Inside an Intel Core i7 2620M CPU does its job. The incorporated graphics chip, Intel HD Graphics 3000, is exclusively available for video output in our test model. This configuration is supported by a four gigabyte DDR3 main memory and a fast 500 GB hard disk with a revolution speed of 7200 rpm. Aside from various Core i processors, the T420 is also available with a dedicated NVIDIA NVS 4200M graphics card and Optimus technology – at least in the USA. Consequently, the rating of performance contingent parts is dependent on the real configuration and can't necessarily be applied to other models. The Thinkpad T420 can practically be seen as an immediate opponent of the basically similarly configurable Latitude E6420 from Dell. While Dell has opted for a completely new design, Lenovo contrarily sticks to the tested and tried Thinkpad design for the Thinkpad T420. We will show to what extent both vying notebooks differ in or 15 inch, the looks have been maintainedAt first glance, The T420 doesn't seem to differ from the T410 much. But this is deceptive. For one thing, the display's diagonal has slightly shrunk from inches to 14 inches. The same applies for the laptop's height and width, whereas the depth has interestingly gained a bit. The measurements for comparison for the T420 and 32x336x239 for the T410. Albeit, as we will see in a moment, quite a few changes have been made on connectivity, Lenovo sticks to the proven, light clamshell design. No modifications can be found in color or material choice, either. The almost completely black case has been made from plastic. The haptics correspond to the choice of materials. However, the matt and slightly roughened surfaces don't feel unpleasant. The case's stability is basically satisfying. But it still shows the same weaknesses known from the T400. So, in the Ultra Bay slot's area and on the plastic cover above the keyboard. The case can yield somewhat and creak under selective display components stand up well to our warp and pressure tests. It hardly bends when the case is lifted up at its edges. The hinges are first give in before image distortions turn up under selective pressure. In return, the display bezel yields evidently when pressure is applied and allows image deviations to become visible. We like the metallic hinges that hardly teeter after adjusting the opening angle. Surprisingly, they don't cope well in shaky work conditions train journey. Since they are smooth and the base unit is sufficiently heavy, both single-handed opening and closing are possible. The maximum opening angle of even a bit more than 100 degrees doesn't cause any restrictions in any case. In addition to the clamshell design, the ramshorn hook contributes to safety during transportation. It keeps the device securely closed and can be opened easily with the slider on the front edge. Let's start with a tour around the device itself. We notice that the positioning favors right handed users a bit. Depending on the utilization of single ports, a few cables can gather on the left, which may considerably obstruct the work area on the laptop's left. Two of the five USB ports, the display port, the VGA and the RJ45 are found on the left's center edge. In opposition, Lenovo has taken care to place potentially permanently occupied ports, such as the other two USB ports and the eSATA/USB combo port, in the right's rear area in the interface arrangement. In addition, the right accommodates, from front to back, a combo audio socket, the optical drive in an Ultra Bay slot, a 4in1 cardreader that supports SD, MM, SDHC, SDXC, and an ExpressCard34 port. The rear is completed by a powered USB port and a RJ11 modem socket. The power adapter is also connected on the case's rear. To our regret, Lenovo forgets, like Dell in its E6420, to install a USB port in the course of the refresh. Although the eSATA interface also bids a higher data transfer rate than USB increasingly more external mass memories are being offered with USB ports and eSATA is disappearing little by little from the market. In comparison to the competition, we also notice that Dell relies on the utilization of a HDMI port in the E6420 and thus accepts the according restrictions. In opposition, Lenovo remains resolute in installing a display port directly on the device. Compared with its predecessor, the T410, hardly anything of significance has been changed. Merely a powered USB interface has been added. Moreover, the interface layout has been revised, but not really improved. So, if you find cables in the work area beside the laptop disturbing, or if you don't want to re-connect all the cables after mobile use, you can make use of a docking solution. The correlating docking port is, as usual, on the notebook's about docking stations – it remains interesting to see which docking solutions will find their way to Europe. Currently, two models are available for the T420 in the USA The ThinkPad Mini Dock Plus Series 3 US/Canada/LA -> manufacturer's information for about 250 US dollars. It allows connecting three additional external monitors in addition to the installed display. Secondly, the ThinkPad Port Replicator Series 3 -> manufacturer's information for about 280 Slider for opening Left Fan, VGA, RJ45 LAN, two USB hard disk slot Rear RJ11, powered USB, battery, power socket, fan Right Audio combo socket, optical drive, ExpressCard34, 4in1 cardreader, USB USB/eSATA combo port, Kensington Security slotCommunication Alike the T410, our T420 test sample scores with an extensive communication configuration. Everything that is useful and available is installed. A Bluetooth module version is optional, and installed in our test device. It allows data exchange with small, portable devices, such as PDA or mobile phones. Just as optional is a mobile broadband module F5521gw Mobile Broadband also installed in our Thinkpad. The correlating SIM slot is located in the battery compartment. The matching antenna cables are present so that a UMTS/HSPA module can be retrofitted later. In regards to WLAN, various options are given. An Intel Centrino Ultimate-N 6300 AGN agn module is in the test device. The laptop can be linked to Ethernet networks via the Intel 82579 LM Gigabyte Network Connection. Video conferences aren't a problem anywhere with the optional 720p HD camera and this configuration. Security In addition to the obligatory Kensington Lock, the T420 also has a fingerprint reader, among other things. A splash waterproof keyboard saves data from loss in case of mishaps with liquids. Supplies Besides the necessary paraphernalia, such as power adapter and battery, only a bit of printed information is included in the scope of delivery. The user should create recovery DVDs for the pre-installed Windows Professional 64bit immediately after purchase. This isn't a problem with the convenient ThinkVantage tool, though. Warranty The standard warranty for the T-range is three years in Europe. The basic warranty only includes a one year bring-in service in the USA. Various warranty extensions can be purchased Neither design nor layout has been modified in comparison to the T410. Apart from the exchanged STRG and FN keys, we are dealing with a standard layout with clearly arranged key grouping. The blue ThinkVantage key is again the most striking additional key. It opens the well arranged ThinkVantage tools, respectively a recovery process can be started while booting. Just left of it are a mute button for the speakers and microphone and a rocker for volume control. The keyboard's illumination is integrated in the upper display bezel, as it was in the T410. It can be turned on/off with the FN+PGUP keys. The light can help you find your way around the input devices in complete darkness, but it can't hold a candle to backlit keyboards in our opinion. Prolific typists will find the Thinkpad keyboard very pleasing due to its mechanical qualities, well dosed key drop and clear pressure point. Additionally, concave keys add to typing comfort. Unfortunately, the keyboard gets quite loud especially during energetic typing. Nevertheless, touch-typing isn't a problem right from the start. Touchpad and Trackpoint The similarities to the T410 are just as striking here. The touchpad and trackpoint can be independently disabled and enabled via F8+FN. The touchpad proves to have a pleasantly roughened surface with good gliding traits. The mouse cursor control is, again, accurately possible without problems and the multi-touch features respond as expected. Moreover, scrolling via scroll fields at the touchpad edge is also possible. The touchpad's borders can hardly be distinguished from the surrounding case due to a simple component correlating buttons need a bit of getting used to since they are on the beveled edge. They are smooth, respond well over their entire breadth and don't click too loud, either. Alternately, there is also a red trackpoint. It allows just as precise navigating of the mouse cursor. The correlating buttons are fairly quiet. There are no complaints in regards to functionality, of the 1610 format as in the T410, a 169 aspect ratio is now used. The display diagonal has been marginally reduced from inches to 14 inches. In return, the resolution has been increased from 1440x900 pixels to 1600x900 pixels. Thus, there are now so many pixels in the total height as in the previous model. However, the test device has gained a bit of width. As it isn't expected differently from a business device, the display surface has been AR coated. The device thus not only meets the requirements on display workstations, but also is more suitable for outdoor T420 has generally improved in comparison to the T410 in terms of assessments. It is brighter and illuminated more evenly. Merely the black value is slightly lower than in the prior model. Nevertheless, the better brightness results in a somewhat higher contrast. In contrast, the E6420 scores with a significantly higher maximum brightness of 320 cd/m2 and still cd/m2 on average. In return, Dell's laptop has to admit clear defeat in the field of black value and contrast. 197cd/m²190cd/m²214cd/m²213cd/m²223cd/m²221cd/m²210cd/m²198cd/m²194cd/m² Distribution of brightnessLEN40A1Gossen Mavo-MonitorMaximum 223 cd/m² Nits Average cd/m²Brightness Distribution 85 %Contrast 1621 Black cd/m² AdobeRGB 1998 Argyll 3D61% sRGB Argyll 3D Display P3 Argyll 3DAs you can see in the comparison pictures, which have been made with various ICC color profiles, The T420 hasn't been designed for professional image editing. AdobeRGB and sRGB aren't covered. Thus, it is in the same league as Dell's E6420 with the same display size and resolution. Differences in view of color reproduction become visible in comparison with especially high quality screens. They can be found, for example, in Apple's MacBook Pro 13 or in Dell's XPS 15. Even the T420's bigger brother, the T520, scores better an anti-reflective surface and an average brightness of over 200 cd/m2, which is also available in battery mode, the test model is pretty suitable for outdoor use. The display content even stays fairly legible in direct last point we look at for rating a screen is its viewing angle stability. It turns out to our satisfaction horizontally and the image can be recognized even in very narrow angles without ado. As usual in the majority of laptops, the viewing angles along the vertical plane are considerably lower in the T420. Consequently, you can take it for granted that frequent viewing angle adjusting will be necessary to ensure a well legible image, especially during outdoor use. When several people are looking at the screen at the same time, their eyes should be at about the same angles Lenovo Thinkpad T420 4236-NGGCurrently, various models with Core i5 or i7 of the second generation are being offered. To be exact, our test model was equipped with an Intel Core i7 2620M Sandy Bridge CPU. It is presently the fastest dual core processor from the Sandy Bridge family that was introduced at the beginning of 2011. It can process up to four threads at the same time thanks to Hyper Threading. The Turbo Boost technology allows single cores to overclock dynamically from GHz up to GHz, depending on load and cooling capacity. In comparison to the Arrandale processors, the turbo function has been improved among other information Lenovo Thinkpad T420 4236-NGG The DirectX 10 capable Intel HD Graphics 3000 chip incorporated directly in the processor is available for the video output in our test device. Thus, the graphics performance is about on par with an Nvidia Geforce 310M entry level card. Alike the Latitude E6420, models with an NVIDIA NVS 4200M and Optimus technology are listed in the USA. Our T420 has a four gigabyte DDR3 RAM available for the main memory. They are located on one single, inaccessible for the user, chip. Only a second, still unoccupied bank is accessible via the maintenance cover. An intended upgrade can easily be accomplished by the customer. Due to the 64bit Windows 7 Professional operating system, the four gigabyte of main memory can be exploited efficiently, in contrast to a 32 bit version, and there's nothing standing in the way of a RAM upgrade. The processor's memory controller can address a maximum of up to eight gigabyte of DDR3-1066/1333 7 Experience IndexProcessorCalculations per RAMMemory operations per performance for Windows graphics3D business and gaming hard diskDisk data transfer R10 Rendering Single CPUs 64Bit5438 Points Cinebench R10 Rendering Multiple CPUs 64Bit11507 Points Cinebench R10 Shading 64Bit5566 Points Help PCMark Vantage Result 7845 pointsHelp Both the processor as well as the application performance is unsurprisingly a bit higher than the E6420 equipped with a Core i3-2310M. The performance rates are according to the expectations on this hardware configuration. Our test candidate achieved a total score of 7845 points, which is especially due to its high communication sub score, in the PCMark Vantage test for rating the overall performance. Thus, it's even on par with stronger gaming machines, like the Asus G73SW GeForce GTX 460M, Intel Core i7 2630QM, in terms of application Performance Verdict The test device still can keep up with gaming machines like the Asus G73SW in regards to application performance. However, in view of the graphics hardware, it doesn't stand a chance in 3D performance as we expected right from the start. That is confirmed by the results in the Cinebench Shading Test and the various 3DMark benchmarks. Unfortunately, the test results are beneath those that would be expected for a HD Graphics 3000. However, since the power measurements always remain under par, we have to reckon with a defective device. Another indication for this is that the device detection of the ThinkVantage Tools fails regularly. In order to exclude a problem in the settings we checked the BIOS and the energy settings in Windows 7. We will attempt to attain a replacement device for an update review. We would refer to our detailed test of the Intel HD Graphics 3000 chip and to the HD Graphics 3000's spec sheet for more information. 3DMark 05 Standard 6131 points3DMark 06 Standard Score 3381 points3DMark Vantage P Result 1696 pointsHelp Transfer Rate Minimum MB/s Transfer Rate Maximum 102 MB/s Transfer Rate Average MB/s Our test device's hard disk is a ST9500420AS from Seagate. It has a gross capacity of 500 GBs, whereas a part is used as a hidden recovery partition. It achieves according results in HDTune and in CrystalDiskMark tests with a revolution speed of 7200 rpm. A DVD burner is also available as another mass storage device. To be precise, it is an Optiarc DVD RW Noise The T420 always remains fairly quiet regardless of the load. The system noise is a constant dBA in low load. The hard disk is slightly louder with dBA during test laptop just only reaches a maximum noise level of dBA during our stress test GPU and CPU in full load. The operating noise thus always stays at an acceptable level. The power consumption assessments 28W max however indicate that the processor doesn't exploit its maximum possible capacity even during the stress test. Monitoring the processor clock rate with the CPUZ tool recorded the default clock rate of GHz for the CPU in the stress test. This means, no overclocking of all four cores and the installed GPU during load. The CPU clocks with GHz when only Prime95 is activated. When Furmark is added, the system throttles down to GHz. We can also only record a maximum of GHz in Cinebench R10 Single Core rendering. The clock rate meter stays at the same level in multi core rendering. The i7-2620M's maximum possible clock rate of GHz is consequently not exploited in any tested state. Nevertheless, the benchmark results that are determined in Cinebench R10 stay within the i7-2620M CPU's expected range and don't show any irregularities in regards to a possible throttling.

The Core i7 2620M dual core processors' core temperatures inside climb to a maximum of 85 degrees Celsius inside. We must point out that the T420 in the configuration at hand hasn't been conceived for graphic-heavy applications, but for office and internet anyway. °C94 °C94 °C87 F °C96 °C96 °C87 F °C89 °C87 °C81 F Maximum °C = 96 FAverage °C = 90 F °C103 °C97 °C89 °C84 °C100 °C101 °C83 °C97 °C96 F Maximum °C = 103 FAverage °C = 95 F Power Supply max. °C = 131 F Room Temperature °C = 71 F Raytek Raynger ST± The average temperature for the upper side under maximal load is °C / 90 F, compared to the average of °C / 85 F for the devices in the class Office.+ The maximum temperature on the upper side is °C / 96 F, compared to the average of °C / 94 F, ranging from to °C for the class Office.+ The bottom heats up to a maximum of °C / 103 F, compared to the average of °C / 98 F+ In idle usage, the average temperature for the upper side is °C / 80 F, compared to the device average of °C / 85 F.+ The palmrests and touchpad are cooler than skin temperature with a maximum of °C / F and are therefore cool to the touch. - The average temperature of the palmrest area of similar devices was °C / 82 F °C / F. Speakers The speakers' quality isn't to be rated as high in an office laptop for professional use as in, for example, a multimedia notebook. In fact both stereo loudspeakers, on the keyboard's left and right, are basically suitable for voice. Music enjoyment doesn't turn up due to the tinny, bass-poor and treble-heavy sound. High quality headphones, connected to the mm audio combo socket, can remedy this. The signal is transmitted clearly, undistorted and static-free in the test audio test only, no measurement.Our test model is at the start with a 57 Wh, 6 cell lithium ion battery in this test. One possibility of extending the battery life is ordering the 9 cell battery. Another is the docking of a 9 cell battery. According to the manufacturer's specs, a total maximum battery life of up to 30 hours is possible. In any case, a maximum battery life short of "only" seven and a half hours is possible with the battery at hand. BatteryEater's Reader's Test determined this runtime in minimum brightness, with disabled wireless module and in energy saving mode. This rate is unrealistic for practical use due to the low and unusable minimum brightness. We execute the WLAN test in a useable brightness, so from level 12 to 15. We can do research on the internet for up to six hours, also in energy saving profiles, in this low load scenario no flash videos. Movie enjoyment ended after a bit less than three hours in the DVD test. It is executed in maximum brightness and disabled wireless modules, as well as in "Video" mode. The battery life nosedives in 3D intensive applications, maximum brightness, enabled wireless modules and maximum performance mode. The BatteryEater Classic test simulates an OpenGL calculation for us and records a minimum battery life of only about an Runtime Idle without WLAN, min brightness 7h 28min WiFi Surfing 5h 59min Load maximum brightness 1h 06min The Latitude E6420 clearly has the lead in the battery tests due to its larger 9 cell battery. Our test laptop's runtimes are nevertheless remarkable in relation to the battery's capacity. That is especially due to the fairly low power consumption. It is a bit lower than that of the E6420 with to watts in idle mode. Surprisingly, the maximum power consumption wasn't as high as expected in the stress test 100% CPU and GPU load. Solely the CPU proves to have a maximum power loss of 35 watts. However, our meters only recorded watts for the entire system. Thus, we checked the setting in Lenovo's PowerManagement in Windows 7 and the BIOS settings. But we didn't find anything in neither place. The settings for mains operation are clearly set to "Maximum Performance" in the BIOS. At any rate, the T420 is also available with a dedicated NVIDIA NVS 4200M graphics card in the USA. The Optimus technology is thus used to keep the power consumption low during low load. Since our E6420 test device is equipped with the NVIDIA NVS 4200M graphics card and Optimus option, our T420 has a clear advantage in power consumption during load Thinkpad T420Apart from the expected performance increase due to the new processor generation, many things tried and tested things have been maintained. This is just as true for the case as for the pre-installed, convenient ThinkVantage tools. Slight modifications and upgrades can be found in the connectivity. Nevertheless, the user still has to live without USB In return, an eSATA/USB port has been installed. The test laptop's communication configuration is comprehensive. All available options are exploited broadband module, Bluetooth version WLAN with standard n support and gigabit Ethernet. We like the 14 inch screen that is marginally smaller than the T410's display diagonal. The desktop's layout has been maintained, respectively even slightly improved in width due to a resolution of 1600x900. There's nothing standing in the way of mobile use with the matt display surface and good brightness. However, the T420 only bids standard fare in terms of color reproduction. According to the manufacturer, a battery life of up to 30 hours are supposed to be possible with the 9 cell system battery and additionally docked 9 cell battery slice. We achieved a plausible battery life of up to 6 hours with our 6 cell battery with a capacity of 57 Wh WLAN test. The T420 has basically been designed for business customers who are looking for a solid office laptop with a good application performance and nevertheless good mobile qualities. A slight performance increase in 3D applications can be expected in the configurations with a dedicated Nvidia NVS 4200M graphics card, which also supports DirectX 11, listed in the USA. However, our test laptop won't mutate to a stronger graphics workstation even with this graphics solution. By courtesy of ...

Lenovo's ThinkPad T series notebooks have long been the gold standard for mainstream business systems because of their strong performance, superior build quality, and best-in-class keyboards. With the 14-inch ThinkPad T420, Lenovo has made a couple of changes, switching the screen to the now-standard 169 aspect ratio and giving it the latest Intel 2nd Generation Core series CPU. Is the T420, $1,179 as configured, the business notebook to beat?Update Read our review of the ThinkPad T460, the latest version of this computer. DesignThe ThinkPad T420 follows the classic ThinkPad aesthetic business users have come to know and love over the years. The matte black, rubberized lid with its simple silver logo and raven black sides, bottom, and interior are all long-time ThinkPad staples, as is the tiny red TrackPoint pointing stick that sits between the G and H keys. Like previous ThinkPad T Series notebooks, the T420 is designed for durability. The rubberized ABS plastic lid, carbon-reinforced bottom, and internal roll cage help protect against shocks and x 10 x 1 inches and pounds with the high-capacity nine-cell battery, the ThinkPad T420 is a bit larger and heavier than the Toshiba Tecra R840 x x inches, pounds, but it's still lighter than the HP Elitebook 8460p 13 x x inches, pounds and the Dell Latitude E6420 x x inches, pounds with its extended battery. Using the standard six-cell battery cuts the T420's length to 9 inches and its weight to pounds. Lenovo's ThinkPad T420s, designed as a lighter alternative, weighs only 4 pounds and measures only x x inches.[Which ThinkPad is Right for You?]Keyboard, Pointing Stick, TouchPadThe classic, spill-resistant keyboard on the ThinkPad T420 features 7 rows with a full range of keys, even rarely used ones such as scroll lock and pause. Enlarged Esc and Delete keys make it easy to perform these frequent functions. The combination of strong tactile feedback and a smile-shaped key surface allowed us to achieve an 86 word-per-minute score with a 1-percent error rate on the Ten Thumbs Typing Tutor test, well above our 80 wpm average. However, the typing experience on the 13-inch ThinkPad X1 remains the industry's best because of that notebook's soft-touch palm rest and even more responsive other ThinkPads, the T420 has both a TrackPoint pointing stick and a touchpad. We're huge fans of the TrackPoint because it provides the most accurate way to navigate around the desktop short of using a mouse, and it allows you to move the pointer without lifting your fingers off of the home row. If you don't like pointing sticks, the 3 x textured touchpad provides accurate navigation around the desktop, and its two discrete mouse buttons provide just the right amount of feedback. However, multitouch gestures such as pinch-to-zoom are not smooth at ThinkPad T420 stayed pleasantly cool throughout our testing. After streaming video for 15 minutes, the touchpad measured a frigid 82 degrees, the keyboard an icy 81 degrees, and the bottom a cool 87 degrees Fahrenheit. We consider temperatures below 95 degrees and AudioThe 230-nit, matte display provided sharp images and plenty of desktop real estate thanks to its optional 1600 x 900 panel. When we watched a 1080p QuickTime trailer for the movie Point Blank, images were sharp and motion smooth with viewing angles solid up to 45 degrees to the left or right. However, when we streamed a 720p Flash episode of Fringe from the edges of objects seemed a little pixelated, perhaps because the screen had a higher resolution than the video. We highly recommend the 1600 x 900 panel, a $50 option, because it shows a lot more of your favorite web pages and documents without forcing you to not as high fidelity as audio-focused consumer notebooks such as the Dell XPS and the HP Envy series, the Lenovo ThinkPad T420 provides surprisingly good music playback. Whether we were playing Kool and the Gang's jazz-oriented "Summer Madness," the bass-heavy "Between the Sheets" by the Isley Brothers, or Motley Crue's guitar-laden "Looks that Kill," sound was accurate and loud enough to fill a medium-sized room. We could even make out a solid separation of sound between the speakers, which sit on either side of the and WebcamThe ThinkPad T420 has plenty of connectivity options, but it's missing a couple of the obvious ones. On the right side are an Express Card 34 slot, a 4-in-1 memory card reader, a USB port, and a USB/eSATA port. On the back are a FireWire port and a powered USB port that allows you to charge devices with the system off. The left side houses VGA, DisplayPort, Ethernet, and one more USB port for a total of four. Conspicuously absent are USB ports and HDMI-out, neither of which are even available as options. Considering that we've been seeing notebooks with USB for over a year now and that Lenovo offers USB on many other ThinkPads the X1 and W520, for example, this is a pretty glaring 720p webcam provided sharp images even in low-light situations. In our dark living room, fine details of our face were visible when we snapped a picture at 1280 x 720 and chatted on Skype in standard def. However, like with many other webcams, our face appeared shadowy if there was a bright light source directly behind; this occurred when we tried snapping a photo while sitting in front of a window with sunlight coming conferencing software features a unique keyboard noise suppression feature that, on our tests, completely muted the sound of our typing as we chatted on Skype. The software also allows you to configure the dual-array microphones for a single voice or group its Core i5 CPU, 4GB of RAM, an Nvidia NVS 4200M graphics chip, and 7,200-rpm hard drive, the ThinkPad T420 was strong enough for anything we threw at it, from playing 1080p video to spreadsheet crunching and light gaming. On PCMarkVantage, which measures overall performance, the T420 scored a strong 8,197, much higher than the 5,596 thin-and-light notebook category average, the 7,728 turned in by the Toshiba Tecra R840, and the HP EliteBook 8460p both have the same Core i5-2520M CPU.The 500GB, 7,200-rpm hard drive booted into Windows 7 Professional in a speedy 48 seconds, much faster than the 65-second category average. The drive took a modest 3 minutes and 5 seconds to complete the LAPTOP File Transfer test, which involves copying of mixed-media files. That's a rate of MBps, a little higher than the 26 MBps category average but well behind the MBps provided by the Dell Latitude E6420 and its 7,200-rpm Oxelon Media Encoder, the T420 transcoded a 114MB MPEG4 to AVI in 43 seconds, 15 seconds less than the thin-and-light average, and on a par with the Toshiba R840 41 seconds and the HP 8460p 42 seconds.GraphicsOur ThinkPad T420 review unit came with Nvidia NVS 4200M and Intel HD 3000 GPUs and Nvidia's Optimus graphics switching technology to toggle between the two for the best combination of battery life and performance. On 3DMark06, which measures overall graphics prowess, the ThinkPad T420 scored a strong 5,583, well above the 4,006 category average, the 5,060 provided by the Dell Latitude E6420 with its Intel HD 3000 integrated graphics, and the 5,032 scored by the HP EliteBook 8460p with its AMD Radeon HD 6470M ThinkPad T420 isn't a gaming system, but its discrete graphics chip is good enough to get decent frame rates on some popular titles. At autodetect settings, the T420 provided a solid 61 frames per second when playing World of Warcraft, a little less than the 86 fps category average, but much higher than the 41 fps that the Dell Latitude E6420 got and the 52 fps scored by the HP EliteBook 8460p, and impressive given that most notebooks in the category have lower resolution screens. With special effects turned up, the rate dropped to a still-solid 32 the more demanding Far Cry 2, the ThinkPad T420 got a solid 37 fps at 1024 x 768 resolution, on a par with the fps category average. When we upped the resolution to 1600 x 900, that rate dropped to a modest 25 fps, which is comfortably above the 20 fps category LifeWith its nine-cell extended battery, the ThinkPad T420 lasts all day and then some. On the LAPTOP Battery Test, which involves continuous surfing over Wi-Fi, the notebook lasted a whopping 10 hours and 36 minutes, more than double the 515 category average and the battery life of the T420s 5 hours. That time is also significantly longer than the HP EliteBook 8460p 601 and the Toshiba Tecra R840 634. Only the Dell Latitude E6420 with its extended battery came close, lasting 8 OptionsThough our review unit carries an MSRP of $1,179, the ThinkPad T420 starts at just $789. For that price, you get a Core i3 CPU, integrated graphics, a 1366 x 768 display, but the same 500GB hard drive and 4GB of RAM as our review unit. If you want discrete graphics, you'll need to buy the $1,089 model that comes with a Core i5 CPU and 1600 x 900 screen, along with its Nvidia NVS 4200 GPU. Configuration options include a choice of storage 320/500GB hard drive or 128/160GB SSD, up to 8GB of RAM, a choice of Core i3, i5, or i7, and several different Wi-Fi cards. Strangely, the webcam and fingerprint reader are not standard, costing $20 and $30 matter what other options you choose, both the 1600 x 900 screen $50 and the nine-cell battery $50 are absolute musts for maximizing your productivity and Fingerprint Reader, and WarrantyLenovo bundles the ThinkPad T420 with the standard set of ThinkVantage utilities. Among these are the ThinkVantage Power manger, which allows you to exert fine control over the system's power profile. We particularly like the Instant Resume feature, which keeps the Wi-Fi card active for 10 or more minutes after you put the notebook to sleep so you don't have to wait for the system to reconnect after you wake utilities include Access Connections from managing your wireless connections, Password Manager, and Rescue and Recovery for Backups. The T420 also comes with Corel DVD Movie Factory for burning ThinkPad T420 comes with a powered fingerprint reader that can read your fingers even when the system is off. Using the bundled security software, we were able to enroll our index finger in just a couple of minutes.

Lenovo ThinkPad T420s MSRP $ “The LenovoT420s is an excellent laptop for business users, and also well worth the consideration of consumers who prefer an excellent keyboard and durable design to flashy aesthetics.” Pros Durable construction High-resolution display Excellent performance Reasonable price Cons Not particularly thin or light Lackluster battery life Display isn’t great for multimedia The ThinkPad T Series is an elder among laptops. IBM introduced the first laptop in the line, the T20, about 12 years ago. Since then the series has been consistently updated and has never once been removed from the market. Only the ThinkPad X Series has enjoyed a similar tenure. IBM’s original T20 was offered only with a display, but over the years the line has expanded. High performance and variants were made available. More recently, Lenovo decided to spin off a thinner, lighter version — resulting in the T420s. Though this is the thin-and-light version of the T420, don’t mistake it for an Ultrabook. The display and maximum thickness of just over one inch seemed modern when the original T400s arrived in 2009, but today it’s merely average. It does allow for a standard Core i5-2520M processor, however, which means performance should be much better than what is provided by today’s thinnest laptops. Lenovo is debuting an Ultrabook version of the T-Series, called the T430u, later this year. Which raises the question Is the T420s a good choice, or is this thin and light losing ground to more modern designs? Let’s find out. Video overview Still in black When Lenovo took over the ThinkPad line from IBM there was widespread fear that the brand would be watered down. Instead, the company has remained shockingly stubborn. This T420s is thin, but its appearance is otherwise not much different than the laptops made ten years ago. From an aesthetic standpoint the use of matte black is a terrible choice, but that’s not the point. Functionality is the focus here. The expanses of non-gloss material ensure that fingerprints are rarely an issue. Dings and scratches also tend to be obscured. While a shiny new consumer laptop may look worse for wear a few years down the road, this laptop will display its scars with pride. The T420s’ designation as a thinner version of the T420 is literal. We’ve had the chance to see both, and the design elements are the same right down to the size of the display bezel, the hinges used and the location of the latch yes, this laptop has a display latch, a feature long gone from consumer products. Connectivity is the only major change. Due to its thinner profile this laptop offers only three USB ports, DisplayPort, VGA, Ethernet and a card reader. That’s down a couple ports to the normal T420, but it’s also much better than what is provided by most laptops of similar size. Better still, the ports are mostly along the rear of the laptop. That’s beneficial because it means peripheral cords are less likely to get in your way. Old-school keyboard Similarities between the T420 and T420s continue with the user interface. The keyboards on both appear to be identical, which means that the thinner model has the same excellent key feel. While most of the competitions — including HP’s own business-oriented Elitebooks — have transitioned over to island-style keyboards, Lenovo has continued on with beveled keys. The result is not as visually attractive, but we think this design is better for high-speed touch typing. Users new to the ThinkPad brand will undoubtedly be tripped up by the location of the function key, which is located where the Ctrl key is on every other keyboard ever produced. This strange layout has been used for years, so it’s unlikely to be changed soon. On the other hand, the T420s offers dedicated buttons for speaker mute, microphone mute and volume as well as double-sized Escape and Delete keys. These enhancements more than make up for the layout’s other oddities. The touchpad is extremely small for a laptop of this size. It’s obvious that you’re expected to use the trackpointer a little red pointing stick in the middle of the keyboard instead. Users who’ve never tackled a trackpointer before are bound to be confused by it, but there are benefits. Once you’ve become accustomed to it you can navigate via mouse without lifting your hands from the keyboard. Great for business, OK for entertainment The T420s is a business laptop, and as such it comes with a matte display, making it possible to use the laptop in many different environments. Even outdoors use is possible with the display’s brightness turned to maximum. Usually the downside to a matte display is less-than-stellar performance in movies and games, and that’s certainly the case here. You don’t get the “pop” of vibrant colors that you receive from a decent glossy laptop display. Performance in movies and games is still adequate, however — and better than matte displays we’ve seen in the past. Part of the reason for this may be the resolution of 1600x 900, which is high for a display. Audio quality has never been a focus of the ThinkPad brand, but the sound the 420s emits is surprisingly adequate. It has all the typical laptop issues with bass and distortion, but maximum volume is sufficiently loud and clear. Cool and quiet At idle, the fan of the T420s isn’t audible. At load, the fan spins up a bit, but still remains quiet. This is one of the least audible cooling systems that we’ve ever heard. You’d think that the low fan speed would result in warm operation, but that’s not the case. At idle most of the laptop’s surfaces are between 70 degrees and 80 degrees Fahrenheit, which is just barely above room temperature. Placing the laptop under load with a stress test did raise temperatures, but almost all surfaces remained under 90 degrees. The only potential source of discomfort is the left rear bottom of the laptop, which is where the exhaust is located. Temperatures here reached 103 degrees, which means that lap use could be uncomfortable if the processor is heavily stressed. That battery goes where? Though built to be thin and light, the T420s isn’t the most portable laptop around. Its 14-inch display puts it at a disadvantage compared to or laptop. The laptop’s weight of about pounds is far from classleading, as well. With that said, the T420s is reasonably small. It will fit in most bags that accommodate a laptop and is light enough to tote around on a regular basis. All ThinkPad T420s laptops come with a standard six-cell battery. In our Battery Eater’s Standard Test it lasted just one hour and nine minutes, but in the Reader’s Test is lasted a reasonable five hours and thirty two minutes. Typical mobile use will result in between four and five hours of endurance. That’s not bad, but it’s not great, either. If you need more life you can buy a three-cell bay battery for $120. This battery replaces the optical drive, which slides out using a fool-proof latch system. With the extended life battery installed, life in the Battery Eater Standard Test goes up to two hours and ten minutes and the Reader’s Test is extended to an impressive eight hours and thirty nine minutes. There’s an optional nine-cell battery for people who need even more life, but it was not provided with our review unit. Software As with other ThinkPads, our T420s came with Lenovo’s bundled ThinkVantage software. It includes a wide variety of software such as ThinkVantage Connections, which is a replacement to the standard Windows wireless manager. Unlike most such bundled solutions, the software offered by Lenovo is actually better than the standard Windows solution. This is also true for the Power Manager. Not everything about the included software is great, however. Lenovo includes advertisements for other ThinkVantage services in portions of the bundled software interface by default, which is annoying. In addition, the Virus Protection section recommends Norton Internet Security. It’d be more useful to recommend Microsoft’s free Security Essentials software. Strong performance Though thin, the T420s is not so thin that it prevents the use of normal Core i5 processors. That’s a major advantage older and thicker ultraportables have over newer Ultrabooks, and its shows in the performance numbers. SiSoft Sandra’s Processor Arithmetic test achieved a combined score of which sets a new record among the laptops we’ve reviewed. The 7-Zip score of 8,247 MIPS is also the highest we’ve yet recorded. Considering the strong processor performance, the score of 2,358 returned by PCMark 7 seems low. The reason for this, as mentioned in other reviews, is that PCMark 7 heavily favors solid state drives. If we take laptops equipped with SSDs out of the running the score of 2,358 is strong. Only the HP Envy 15 scored higher. Nvidia NVS 4200M discrete graphics can be had as an option, but our review unit did not come equipped with it. Instead it relies on Intel’s HD 3000, which can’t run 3DMark 11. 3DMark 06 returned a score of 3,701, which is a bit low for a laptop of this configuration. Combine this with a 1600 x 900 display and you have recipe for terrible gaming performance. Even older 3D games will need to be played with many detail options turned off. No one has ever mistaken a ThinkPad for a gaming laptop, however, so the lack of 3D gaming prowess isn’t a problem. Overall performance from the T420s is extremely strong, held back only by the mechanical hard drive. Solid state drives are available as an option. We highly recommend them if you’re interested in maximum performance. Conclusion The ThinkPad T420s is another example of Lenovo’s stubbornness. Besides the hardware, which is quick, there’s nothing about this laptop that is particularly modern. The entire design philosophy, from the boring matte black surfaces to the beveled key caps, could easily be at home on a laptop built five years ago. But being stubborn isn’t bad when you have it right. This is a laptop built for people who use their laptops for work every day, and for that use the T420s is perfect. It’s simply a miniaturized version of the T420, offering the same performance in a more portable package. While the T420 might be used around an office, the T420s can be taken nearly anywhere. You might expect to pay a higher price for the slimmer chassis, but that doesn’t seem to be the case. Right now our review unit can be yours for just $999, while a similar T420 is $949. That’s not much of a difference. The only weakness of the T420s is battery life. It’s not terrible, but it’s a little below average for a modern ultraportable. The included three-cell extended battery does extend life, but it requires the removal of the optical drive and is an additional cost. It’d be nice if this laptop managed six or seven hours in real-world use without additional juice. One minor disadvantage can’t spoil this party, however. The T420s is an excellent laptop for business users, and also well worth the consideration of consumers who prefer an excellent keyboard and durable design to flashy aesthetics.
