Just about every night I put my Windows 7 computer to sleep, and then I turn off the power to my bluetooth keyboard. Almost always, the next morning my computer has woken up, keyboard still off.
I'm using a Microsoft Wireless Desktop 7000 keyboard (no mouse) and the associated USB adapter. Everything is setup so my keyboard can wake up my PC.
Why is my Windows 7 computer waking up after I put it to sleep (without any keyboard input)?
