Windows – What’s waking up the PC

sleepwindowswindows 7

When I place my PC to sleep, it goes to sleep for 2 min and then wakes up again on its own.

I ran cmd.exe as an admin and then typed powercfg -last wake and -requests and I got nothing really that can direct me to figure this out. Any other suggestions? I've disabled many devices from waking the system up already including the keyboard (but not the mouse).

C:\Windows\system32>powercfg -lastwake
Wake History Count - 1
Wake History [0]
  Wake Source Count - 0

C:\Windows\system32>powercfg -requests
DISPLAY:
None.

SYSTEM:
None.

AWAYMODE:
None.

It could be a Ghost. Or a demon.

Some things that caused this same issue for me were:

  1. I had a very sensitive mouse and even though I was in bed, the mouse would move just very slightly but not noticably, and that woke the PC.
  2. I have also had a problem with USB devices (keyboard/mice/Wireless adapters). Sometimes, and usually over a period of several years, the ports on the PC will become loosened - or something, causing the USB device to move around a little if the desk gets knocked. This caused the PC to play the "USB device removed and inserted" sound and it also caused my PC to wake from sleep.
  3. Check out your Scheduled Tasks. You're bound to have a few if you're not the type to manually delete them all. If updates are cheduled to run in the background this could also be waking your pc. Look out for Google, Apple, Adobe and Java in particular. I always see them in Task Scheduler. And somehow Google update keeps reappearing.
