I have an alum MB with boot camp installed with Vista. I have set the power options in Vista to turn off the display and go to sleep. The only problem is that it doesn't do either in Vista with the power cord plugged in. I've gone away for hours and the computer is still "awake" even though it's supposed to go to sleep after 1 hour. Also the external monitor is still on showing the background image even though the display is supposed to go off after 15 min. Anyone else having this issue?
