That may have something to do with it.
Nah, it happends when their attached or not.
Perhaps you set it to auto-update the OS at night? I've never heard of that turning on the computer, but I suppose it could happen.
Perhaps try disabling some of the activation features in the BIOS such as the Keyboard input or network wakeup mode.
I've never set it to update vista or ubuntu automatically. Plus, when the computer's off the wifi's off, right?
I'll turn off the keyboard and the network thing, though.
if you mean the monitor, just turn it off.
You clearly have not seem my computer. When I got my case I decided I wanted it to be kick ass. Now it lights up my entire room :D
But I'll try all that tomorrow.
