Contra
- Display TN de bajo contraste y escaso ángulo de visión
Con el LifeBook U745, Fujitsu tiene un Ultrabook de 14" en su serie. El hardware va dentro de una carcasa presentable y elegante de aluminio y magnesio. Gracias a su procesador Core i5, no le falta potencia de cálculo. Un SSD asegura un sistema rápido. Por lo general, el ordenador funciona prácticamente en silencio y apenas se calienta. Además, tiene buenos dispositivos de entrada. La batería aguanta bien, pero no es nada sobresaliente. Sin embargo, los competidores como el Dell Latitude 14 E7450 y el Acer TravelMate P645-S aguantan bastante más.
Por desgracia, Fujitsu daña la buena impresión del ordenador con la elección del display.
El panel integrado es un display TN de bajo contraste con escaso ángulo de visión, algo inapropiado para este nivel de precios.
