Trying to prevent Windows from hibernating/sleeping automatically
- by user328821
My Dell XPS 8700 (Win 7) suddenly began putting itself to sleep at 6pm daily, even if I'm typing. I don't know what caused this to occur, except possibly a windows update that took place in the middle of the night. I initially went into settings for power and saw 2 plans set up, one from Dell and the other window's Power saver plan. I set both to never for sleep and hibernate yet it still occurred. I have current drivers and a fairly new UPS that has software to set to shutdown only after power loss.
Dell is of little help, can anyone point me in the right direction?
I did do the powerdfg -energy program and came up with this:
