I pushed F2 and it is on full. I unchecked "automatically reduce the brightness of the display before display sleep" in Energy Saver... and the screen itself doesn't go to sleep unless the system is inactive for 15 minutes. When I am using the computer the screen is on full. If I let it sit around for a few minutes it gets dimmer (say 70%)... when I move the mouse it comes back on full. I'm stumped!
