I just got a Dell Latitude D810, and whenever it runs on battery power the display is dimmed. I have looked at/tweaked every power and display setting I can find, and cannot seem to keep the display from dimming when the laptop is unplugged. My video card is an ATI Mobility Radeon X300.
Does anyone know what I can do to keep the display from dimming? I have looked at Control Panel > Power Settings, and all of the tabs in Display Properties > Settings> Advanced. What am I missing?
