I have Windows XP (SP3) running a tablet PC. The PC is configured via the 'Display Properties' ( 'Screen Saver'-> 'Power') to the 'Always On' power scheme.
The issue I am having is that even when the tablet is plugged in the Screen goes blank after 15 minutes, and the entire system goes into standby mode after a hour or so.
Is there some other settings (i.e. group policy) that could be controlling the power behind the scenes?
