Contra
O Fujitsu LifeBook U748 é um portátil empresarial sólido, assim como seu antecessor. A atualização da CPU melhora o desempenho a um custo para a duração da bateria, pois consome mais energia. No geral, o LifeBook U748 é um dispositivo impressionante com uma boa tela multi-touch e um teclado decente que é confortável para trabalhar. O ruído do ventilador é gerenciável, mesmo que às vezes possa ser frustrante, enquanto os alto-falantes e a webcam são bastante comuns. Esses dois componentes são frequentemente ignorados nos dispositivos empresariais.
O Fujitsu LifeBook U748 nos conquista com sua boa tela, SSD rápido e muitos recursos de segurança necessários para dispositivos empresariais. Infelizmente, o TouchPad abaixo da média e desatualizado permanece o mesmo do modelo do ano passado.
A Fujitsu equipou o LifeBook U748 com o mesmo, muito criticado TouchPad do seu antecessor. Em contraste, gostamos do design fino e da base estável, que parece e se sente premium. Uma boa seleção de portas completa o pacote, embora teríamos gostado de uma porta Thunderbolt 3.
O Fujitsu LifeBook U748 recebe uma recomendação nossa, pois oferece um bom pacote geral. No entanto, a concorrência continua a melhorar, e assim o LifeBook muitas vezes terá dificuldade em acompanhar o Lenovo ThinkPad T480s.
