Windows Insomnia
A surprising number of Windows computers are prone to waking from Sleep Mode without being told to. Windows being Windows, there's a huge and growing list of ways that can happen.

Re: Windows Insomnia
I was having this issue with my computer when I first put it together. I think it was the mouse that was doing it. So now I just can't wake up the computer with my mouse.
