The exterior notebook will surprise fans of minimalism and black. The platform is large enough. One part is occupied by the keyboard is slightly recessed into the surface, the other takes the touchpad. The hinge mechanism is shown taut elongate loop, but the Laptop search Lenovo can be opened with one hand. By the way, the maximum opening angle of 130 degrees.

The density of pixels per inch – only 106 ppi.

The situation is aggravated matrix TN, and hence the widespread visibility can only dream of.

Matte screen surface, so that the Laptop search Lenovo B 70-80 can be run at the window, even on a sunny day.
Bad sound – the trouble with many Laptop search Lenovo computers, except, perhaps, the media. However, in terms of acoustics Lenovo B70-80 pleased us: sound is quite loud, distortion is observed.

Marked with white keys and additional functionality, and even painted orange. As for the so-called “hot” keys, they are not out of the general tone of the entire keyboard. So, we have appreciably rounded single-row [Enter], and beneath it – a small [Shift]. Left [Shift] is much larger, and the unit turned dial also rather big and it’s nice. As for the process of typing, it is possible that not everyone it seems comfortable. The fact that the keys are very mild stroke and a low rate of return. However, it should be noted that they are triggered and quiet enough.
Under the touchpad keyboard are slightly offset to the left. He’s a bit rough surface, and clear boundaries. The touchpad is very responsive, the team will perform without delay.
