win7 keeps turning it self on from sleep mode

[unwashed potato!]

this is happening pretty much every other day now. i put computer to sleep when i go to bed, but then when i get up it's on again. i check when i go to bed that it does indeed shut down but at some point something is brining it out of sleep.

it's prob not a virus but i'd like to know if there is any way to find out what it could be waking it up?

i'ts most annoying as i have my emails synced to this machine so if i check from phone i can't get any as they've been downloaded here

Go to command prompt and type;

powercfg -devicequery wake_armed

and it will tell you what last woke the pc, on mine it was the wireless mouse so I stopped it from being able to wake the computer in device manager.

first post on this forum and it was a winrar! turns out it's my keyboard which may be the R key as that's got issue when pressed it often doesn't do anything.

how can i disable keyboard from waking as it's the mouse that i use any way, plus anyone know what saitek warranties usually ae as i've had this just under 2 years
