Windows – Laptop keeps waking up from sleep (Windows 7)

hibernatepower-managementsleepwake-on-lanwindows 7

Laptop is fully charged before I put it to sleep and when I come back more than 12 hours later and resume it, the computer only has around 10% left.

I have used the powercfg lastwake and powercfg -devicequery wake_armed commands to no avail and have also disabled all the wake on LAN (WOL) options.

I checked the event log and after putting the computer to sleep, 3 hours later it wakes up and loops through a constant cycle of going to sleep and after 29 seconds it resumes. Then 1 minute 46 seconds later it goes back to sleep. It keeps repeating this 2 minute 15 minute cycle over 150 times in the log.

There's also a lot of other events logged, but how would I stop my computer from waking up at all unless I explicitly resume it from sleep?
