    Windows will _sometimes_ not sleep - related to pending updates?


    I've been trying to diagnose my PC's insomnia troubles

    Code:
    powercfg /requests
    shows "None" for everything

    Code:
    powercfg /waketimers
    shows a single wake timer for backup scan many weeks in the future.

    Timer set by [SERVICE] \Device\HarddiskVolume3\Windows\System32\svchost.exe (SystemEventsBroker) expires at 2:09:33 PM on 10/23/2019.
    Reason: Windows will execute 'NT TASK\Microsoft\Windows\UpdateOrchestrator\Backup Scan' scheduled task that requested waking the computer.
    This is the same regardless if my PC goes to sleep or not, so I know this is not the problem.

    I've generated energy reports for both when my computer does sleep and the current state it is in now when it will not sleep.

    energy-report-not-sleeping.html.txt
    energy-report-normal-apps.html.txt
    energy-report-fresh-boot.html.txt

    Nothing really sticks out to me. In my current "energy-report-not-sleeping.html" I am actually down 1 USB device as my headphones are unplugged, but everything else is the same and plugged in to the back of my computer where I wouldnt be changing ports.

    So I came here to post and in the box above it says to check my windows version number: 1809 Build 17763.774

    Then I thought, well maybe I'm not on the latest and I go to check windows updates where I have 3 pending install:
    • Defender KB2267602
    • Software Removal Tool KB890830
    • Cumulative Update KB4519338


    Now, I don't think any of those updates have fixes to my problem (as my computer slept fine before these appeared) however given I cannot find anything else I am wondering if by chance a "Pending install" could be a reason my computer is not sleeping.

    I know without a shadow of a doubt if I update and reboot my PC will sleep again, so I'd prefer to keep it in its current state to try and diagnose what is keeping it up at night or if my current guess is correct

    Try

    powercfg /a

    See what is reports

    Have you looked at devices in Device Manager, any reporting an error?

    Did this just start recently. View update history, particularly driver updates.

    No yellow or red flags in the device manager list

    Code:
    powercfg /a
    The following sleep states are available on this system:
        Standby (S3)
        Hibernate
        Hybrid Sleep
        Fast Startup
    
    The following sleep states are not available on this system:
        Standby (S1)
            The system firmware does not support this standby state.
    
        Standby (S2)
            The system firmware does not support this standby state.
    
        Standby (S0 Low Power Idle)
            The system firmware does not support this standby state.
    Looks like last update was 9/29 for a bunch of windows/.net udpates

    Nvidia was updated on 10/1

    Does the nvidia data align with when problem started?

    I don't believe so, but hard to say.

    The problem happened again and I have both pending installs on windows updates and there is a new nvidia driver released today, which has not been installed.

    I guess I'll complete the pending installs on windows, leave nvidia alone for now, and see if the problem goes away again

    - - - Updated - - -

    Welp I guess it is the pending installs after all. I installed them all and did the reboot, still have same programs and powercfg results, and nvidia is still unchanged.

    Sorry not following.

    After bringing your machine up to date is it now sleeping consistently?

    oh ya, guess my wording wasnt correct above. it sleeps again after updating windows.

    so at this point a "pending install" in windows update prevents the computer from sleeping as that is the only thing that consistently changes and affects the sleep
