PC is "randomly" waking up from sleep. Sometimes it does that 5 hours after i put it in sleep but sometimes it takes just 30 second.
So i ran powercfg -lastwake but it shows nothing :
C:\WINDOWS\system32>powercfg -lastwake
Wake History Count - 1
Wake History [0]
Wake Source Count - 0

-hibernation - disabled
-waking up using network - disabled
-timers - disabled
