Lenovo Z40 review

 

Avoid this budget laptop no matter the cost

Decent performance

Poor build quality ; Short battery life ; Narrow viewing angles

Affordable ; First-class keyboard

Narrow vertical viewing angles ; No touch screen ; Hollow audio ; Brief battery life

Unfortunately, the Lenovo's 4-cell lithium-ion battery was outclassed by the competition: In our grueling battery rundown test, the laptop ran out of steam after a lackluster five hours and ten minutes. The next-shortest-lived contender had two hours'...
