After some research I have found that VirtualBox causes Windows to wake up from sleep mode. At least that is what happens to me.
The following are the steps I've followed:
I regularly let Windows going in sleep mode so o my way back I find everything as it was before including VirtualBox running and its VMs.
After about one minutes of sleeping mode, Windows wakes up again 'autonomously', without my intervention.
On the Command Prompt (executed with admin privileges) I ran the command 'powercfg -lastwake' in order to know what has woken Window up the last time.
The following was the output:
Code: Select all
C:\Windows\system32>powercfg -lastwake
Wake History Count - 1
Wake History [0]
Wake Source Count - 1
Wake Source [0]
Type: Wake Timer
Owner: [PROCESS] \Device\HarddiskVolume4\Program Files\Oracle\VirtualBox\VBoxSVC.exe
At that point Windows didn't wake up 'autonomously' as expected.
Any ideas how to prevent that? or to force VBox to accept the sleep mode from host?
Thank you
P.S.
VirtualBox version: the last plus guest additions
Windows 10.
