Pro
Contra
O Lifebook U747 é um bom portátil. A Fujitsu dificilmente comete erros. Ele oferece uma excelente tela, boas durações da bateria, e um teclado que permite uma digitação confortável. A carcaça é estável, bem construída, e o seu design combina com o campo empresarial. Isto também pode ser dito sobre a diversidade das interfaces. Embora o Thunderbolt 3 não esteja instalado, isto seria mais um problema de luxo do que um verdadeiro ponto negativo. As temperaturas do modelo de teste permanecem sempre baixas e a ventoinha quase sempre está inativa.
O qual resulta em uma breve lista de desvantagens: Embora a ventoinha seja relativamente silenciosa, ela produz um ruído de alta frequência quando começa a funcionar. Certamente, este não é um motivo para sua exclusão, mas é perturbante. O mesmo acontece com os alto falantes e a webcam instalada. No entanto, não é habitual que estes componentes sejam um pouco ignorados. A maior desvantagem é o substituto do mouse. A Fujitsu não instala um touchpad Precision e por isso é um pouco ultrapassado - e o touchpad, portanto, não é tão bom quanto poderia ser. Infelizmente, as teclas do touchpad também deixam uma impressão muito inferior e imprecisa. Um TrackPoint que poderia ter compensado pelo touchpad não é instalado no Lifebook. Finalmente, o período de garantia é um pouco curto, em comparação com os concorrentes.
A Fujitsu envia um forte participante para competir pela coroa empresarial com o seu Lifebook U747. Infelizmente, o touchpad nada ideal, estraga a boa apresentação do poli funcional empresarial.
Apesar do touchpad, o Lifebook recebe uma recomendação de compra, dado que, no geral, é um aparelho bem concebido. No entanto, a concorrência não facilitará as coisas para a Fujitsu, dado que este setor do mercado é muito competitivo. Um rical muito forte, certamente é o Lenovo ThinkPad T470 que se sai melhor que o Lifebook em muitos aspectos; apenas su atela poderia se considerar pior. O novo Dell Latitude e os novos modelos Elitebook da HP (Latitude 7480 e Elitebook 840 G4) com certeza serão rivais fortes. Os testes correspondentes serão publicados em breve.
