I haven't done any updates of OS or drivers. I have the Generic PnP driver (which seems right from other threads). Everything was working fine, but today, when I go to dim my monitor with the hotkeys, the display slider shows up and moves as I hit the hotkey, but the monitor stays at full brightness. Also, when I unplug the machine, it also stays at full brightness. I did restart.
