Weird is right, doesn't work on my Medion laptop. Just keeps getting
darker. I do have a function
key F7 key combination that adjusts the brightness of the screen. I have
noticed at times when
the PC has been asleep that I have to brighten the screen manually using
those keys to get it
back up to brightness. Both of these issues with my PC happen on 10.04
and 10.10 something
I can live with here.
