Hi,
So this problem occurred after I did a clean install of windows 8 (mine come with Win 7).
I can't adjust the brightness, the hot-key/shortcut didn't work, others are working with no problem at all (Airplane mode, backlit, etc).
Since this is a clean install, I assume everything should work without any problem.
Any of you have this problem? If yes, how to solve the problem?
Thanks!
