    Oh.

    Sorry, I haven't got any useful suggestions unless there were any clues on those Kernel-General events [unless they were merely event 12 entries, "The operating system started at system time ..."].


    Best of luck,

    Yes the Kernel-General events were just advising that the system had restarted

    I have disabled ALL tasks in Task Scheduler
    I did not know such a facility existed.
    There is a facility to disable All tasks history but that just prevents their history being available for examination in TS.


    Have you checked the time set for system maintenance?
    Start menu,
    Windows system,
    Control panel,
    [Set View by to large/Small icons, just so you can see everything],
    Security & maintenance,
    Maintenance dropdown arrow,
    Change maintenance settings.

    Check the time and, if relevant, unset the wake the computer checkbox,
    If you change anything, make sure you click on the OK button at the very bottom of the window & give Admin permission to save the change.

    I've checked this. Automatic Maintenance is set to run at 2am daily, and the wake option was already unchecked:

    Have you checked through the various options available such as :
    settings>system>power>power & sleep>additional power settings and
    settings>update & security>troubleshoot>additional troubleshooters>power.

    Thanks for the suggestion. I've just had a look at those areas, but I don't see anything that would trigger waking from sleep mode.

    I wonder if a Task scheduler task might be involved.
    What did you do what you say has disabled all tasks?

    Have you also tried "powercfg waketimers" towards the end of your work session, just in case there is some hidden task ?

    I meant that I had manually disabled everything in Task Scheduler (apart from MicrosoftEdgeUpdateTaskMachineCore1d748b511302c98, which can't be disabled but which is only triggered when a user logs on)

    Aha....I've just run that and it has revealed the item below, which wasn't in the Task Scheduler. I've now disabled the HauppaugeTVServer.exe service, and will see what happens...

    Code:
    C:\WINDOWS\system32>powercfg waketimers
    Timer set by [SERVICE] \Device\HarddiskVolume3\Program Files (x86)\WinTV\TVServer\HauppaugeTVServer.exe (HauppaugeTVServer) expires at 20:00:00 on 09/12/2022.

    Those are a very, very small proportion of TS tasks.
    In TS's left-hand pane, click on the dropdown arrow next to the Task scheduler library entry and you'll be able to browse within the huge TS library of tasks.

    You will not be able to disable them all.

    In TS's opening screen, look in the Task status section. Set its period to last 24 hours. See if any tasks ran when the problem occurred.
    - You'll need to expand each one individually to see its time records.


    All the best,
