LCD brightness on TC1100
in [Tablet PC]
|
From: OceanRider on 10 Oct 2007 15:19 I remember my screen would change brightness depending on if it was plugged in or not. I don't know when this stopped working but recently I decided to try to figure this out. When I go to Tablet and Pen Settings, Display, the Screen Brightness portion is greyed out. This wasn't always like this. I am running XP SP2. I have done a Windows update so everything seems to be up to date for that. Any help would be greatly appriciated. Thank you
From: Josh Einstein on 11 Oct 2007 20:35 This typically happens if you upgrade to video drivers from Intel or whoever makes your graphics chipset instead of HP's. I don't know much about hardware or driver development but this brightness feature appears to be very fragile and tightly coupled to the specific driver version that came with the tablet.
