A recently encountered problem on a laptop Lenovo, from the range Ideapad, gave us a few headaches.
Symptoms are the following: Low brightness of the display and the impossibility of controlling the intensity of light in any way. Even if the light indicator looks like it is at maximum intensity, pe display Only something can be seen, and the intensity could not be controlled at all. Not even from the keys F11 and F12.
In most situations this problem of reduced brightness of the laptop screen appears as a result of a update de driver al integrated video cards. Intel HD Graphics. In our situation, it was the Intel HD Graphics 4000, which after a driver update, left us a little in “darkness”.

For those who have not yet solved the problem of the low brightness of the Lenovo Z500 screen, you are the guilt of the drivers, but do not wander so much, I don't know if someone has already posted this method, the trouble takes place when the headlights are made or you can touch the adjustment of the brightness with the F-11+F12 keys.
Turn off your PC Restart it by holding down the F12 key which is the most of the brightness, as soon as the writing Lenovo Bella Illuminata appears you can leave the F12 button, and you're done.
Try to believe, a salutone to all
