My computer wakes up randomly in the night, I've always assumed it was due to the mouse moving a pixel from random vibration of my desk.

And, side note, would it be too much to ask that after a billion dev-hours effort in to the most popular consumer OS on earth, that it could figure out that a 1-pixel movement at 3:28 AM does not mean I want my display to light up and stay on for a full 60 seconds? And while we're at it, why is the only way to send Windows to sleep (one of the most common things I do with a hotkey) a four-key combination (win+x,u,s)?
