Brightness not working upon waking from sleep
Posted: Sat Mar 05, 2011 11:38 pm
I recently did the windows update to W7 64-bit SP1 and one problem has transpired. I put my X200 to sleep and when I resume the brightness hotkeys have no effect. There is no OSD nor any visible changes in brightness while pressing Fn+brightness up or down. I am consistent in my updates thru "Lenovo update and drivers" and Windows Updates so I'm thinking that SP1 has caused this dilemma.
Is there anyone else who has noticed this problem?
