    Home Forums AskWoody support Windows Windows 10 Questions: Win10 Can’t sleep

        I’m suddenly having trouble getting my desktop PC to go into sleep mode, which I need from time to time because the fans are noisy. Until recently it wasn’t a problem. But in the past two weeks when I put it into sleep the computer stops for a second, then powers back up.

        I’m running Win10 version 19041, 8GB of RAM, AMD FX processor.

        Have you tried unplugging the various bits from it that you can, like any USB devices (keyboard and mouse) and network cables, then put it to sleep, to see if that stops it? If so, you can use trial and error to see which one is at fault. In my case, when I had this kind of thing happening, it turned out to be network related. Once you have the cause narrowed down, you can better figure out how to fix it!

        If you set Windows to sleep when you press the power button, you can unplug the mouse and keyboard at the same time, otherwise you probably want to do them one by one so you have a way to tell it to sleep, of course.

        The next step (if it still wakes even with all the unpluggable stuff unplugged) would be to go to the system event viewer and see if you can find something unusual in there.

          Or look in Task Manager and see what running that wakes it.

        Being somewhat unskilled, what would I look for in either Task Manager or System Event?

        Also check for updated video drivers.

        Admin elevated Command Prompt > ‘Powercfg /requests’

        Lists the current tasks or processes that are preventing sleep.

        Hi JohnW

        Ran powercfg/requests and the reply to all was “none’

          Then I would follow up with all of the earlier suggestions from Ascaris, and report the results here.

        Two most common reasons I’ve seen for this with Win10 is Windows Updates and video drivers. Check Windows for updates and make sure you have the latest video drivers installed.

        I just ran — powercfg -lastwake — in a regular Cmd Prompt and got — High Definition Audio Controller — as usual. I ran Elev Cmd Prompt — Powercfg /requests — as you did and got 3 lines dealing with a Garmin Express update earlier today – BUT NOT – anything about the Audio Controller.

        So try the “lastawake” phrase; I don’t know a resolution just because it may say HD Audio Controller but report IF you get anything and the others can go from there.

        I may have found the problem: Webex Teams. When I shut it down I can make the computer go to sleep.
