    Computers turn on randomly


    I have two Dells- Optiplex 780 & 790 both running Win10-1903. I usually keep these in "Sleep" or "Hibernate" mode when I'm not using them. Well I've noticed that at random times during the night these computers will start up and run 10 minutes or so then return to Sleep or Hibernate. During this time the harddrive light shows activity of some sort. If I turn the monitor on it just shows the usual log-in screen. Does anybody know what's going on here? Are my computers possessed? Do I need an exorcist?

    :)

    Computer Randomly Turns on From Sleep

    I only saw this thread now, otherwise I would have suggested this sooner.
    I had that same problem you are having, my computer was waking-up from S3 and the culprit was my X7 mouse.
    powercfg -lastwake also listed the HID keyboard device which was an extension of the mouse.
    Besides going in device manager and setting everything to not being able to wake-up the computer from S3, I also did this to the power profiles:

    Worked for me.
     
  3. Windows 10 freezes randomly


    I had already tried turning off fast startup, to no avail.
    Will look at the list you provided, thanks. Hard to do when computer freezes on the Windows loading screen though. *Biggrin
    I had tried that as well... no result.
