i've got a Dell laptop so it might be different on mine, but when i was looking at the BIOS yesterday, there was a part of the BIOS that allowed you to control what the power button did when the power supply was plugged in or not. i know you've said you've updated the BIOS but have you seen this in the BIOS.
another one, maybe a little bit stupid, but when you shut your computer down, are you clicking on the power button option, or choosing 'Shut Down' option for the drop down menu. i say this because for the first day or so of using Vista for the first time, i was clicking the button that has the same symbol as the power button on the laptop, and it was just hibernating, rather than turning off.
hope this helps, but i'm just a newbie lol, so someone who knows what they're talking about might have an answer
