I have XPS9100 DELL desktop computer awakes out of the sleep mode without me prompting it. I have 64 bit OS Before I go to sleep I put that in sleep mode but in the morning I see its awake and I try every setting possible but could not help I have tried this command and here is what I got and I am not sure what to do. C:\Users\NAME>powercfg -lastwake Wake History Count - 1 Wake History [0] Wake Source Count - 1 Wake Source [0] Type: Wake Timer Owner: [SERVICE] \Device\HarddiskVolume3\Windows\System32\svchost.exe (wuauserv)
