O Lenovo ThinkPad T480 faz muitas coisas bem e não apresenta falhas reais.
A tela que é muito sensível à pressão, bem como o SSD desacelerado, mas ainda poderoso, são os principais pontos de crítica que temos para o ThinkPad T480. De fato, essas questões poderiam ter sido evitadas pelo fabricante em primeiro lugar. Além disso, o comportamento de afogamento estranho que surge sob carga (pesada), bem como a queda inexplicável no desempenho que ocorre durante as sessões de trabalho prolongadas nos deixam bastante confusos e perplexos. Felizmente, esses problemas podem ser resolvidos por meio de uma atualização manual do BIOS (para a versão 1.1).
Neste cenário, temos vários aspectos positivos, como a tela brilhante e rica em contraste, os excelentes dispositivos de entrada, muitos recursos de segurança, a bateria secundária prática e o ótimo desempenho (com algumas limitações). Se você está procurando por um portátil de alta qualidade com muitos recursos de segurança, você não pode errar com o ThinkPad T480, especialmente se você se qualificar para o Programa Campus. O hardware e a placa gráfica dedicada, em particular, garantem que o portátil esteja apto para todos os cenários de uso modernos (embora de forma limitada). Além disso, o T480 ainda é um dispositivo muito móvel, o que o torna um ótimo portátil empresarial que é adequado para muito mais do que apenas um trabalho de escritório.
Mesmo com o preço de desconto de 1399 Euros (~$1725), o nosso dispositivo de avaliação ainda não é uma verdadeira pechincha. Um cliente normal terá que desembolsar uns fantásticos 1700 Euros (~$2096) por este portátil. No entanto, ainda recomendamos, pelo menos após a atualização do BIOS.
