Hi, this is my first post. Sorry for any noobyness.
Yeah, my laptop is outdated and lenovo didnt update the Power Management drivers.
I googled around alot but didnt find any solution and read that it is a Windows 8/ Intel's graphic drivers bug.
Brightness adjustment doesnt work. It stays on full.
I tried editing the file BrightnessControl in regedit to 0 and 1. Didnt work.
Help will be appreciated.
