Ideapad z500 brightness can't increase
I work in Bulgarian shop and i sell IT. I got too many mails from my custumers about this problem with te display. Today i try many thinks and i found solution. Its funny but the right way is simple. Just instal the driver for intel vga from the original lenovo support center in section z500. I try many times to instal the proper driver from the original cd that comes with the laptop and im sure that the included driver in this cd not work proper. It cant control the brightnes of the display. Download the correct drivers from here

I install furst intel wireless display driver but im not sure that this step is needed. Try only with "Intel Video Driver for Microsoft Windows 8 (64-bit) - IdeaPad P400 Touch, P500, Z400, Z500" then if you dont have effect try to install "Intel Wireless Display for Windows 8 (64-bit) - IdeaPad P400 Touch, P500, Z400, Z500" too. Wen you finish with the integrated intell controller install the nvidia one "Nvidia Video Driver for Microsoft Windows 8 (64-bit) - IdeaPad P400 Touch, P500, Z400, Z500" it work 100%.
If you want to try clean install and you dont know how to enter bios mode do that:
1. turn off your laptop
2. pres the "novo" button for 5- 6 secounds and you will get choice menu.
3. better turn off uefi boot functions.
