    Won't Enter Sleep - legacy kernel caller

    I built a new PC about two months ago, and up until last week, It went to sleep on its own, of manually via power options. The monitor goes to idle, but immediately comes back to login screen, and PC never enters sleep.
    I've done a number of searches, and most of these errors seem to suggest driver issues. Other than install Logitech software for my joystick, I haven't added anything new to my system, or updated any of its drivers.

    When I run "powercfg -requests" I got Audio stream from Realtek, but after close my browser that would disappear. Now I still get "PERFBOOST: [DRIVER] Legacy Kernel Caller "

    I've run Powercfg -requestsoverride Driver "Legacy Kernel Caller" System, but it does nothing, kernel caller still remains.
    Last night after running "powercfg -requests", it actually was showing nothing running at all, yet the darn thing still won't enter sleep.

  3. Legacy Kernel Caller, cannot be overridden by Requestoverride since Windows 10 version 1809. PC won't goto sleep.

    Hi



    The HW is a TV receiver card, but irrelevant.

    I can trace the frequency of “Legacy Kernel Caller” and any other PowerRequest. When I remove this HW the “Legacy Kernel Caller” disappears, and the PC will go to sleep after the scheduled period.

    So I think we have isolated that “Requestoverride” does not work at least for “Legacy Kernel Caller”.

    The settings were not changed from earlier on 1803, and I could also then trace the frequency of “Legacy Kernel Caller” and any other PowerRequest..

    But then override worked.



    I have tried most of the below, even set the power plan to defaults and recreated the power plan, which was just timing of turn off display and put the computer to sleep.

    The drivers are the newest.

    Why should update from 1803 to 1809 justify a bios upgrade.



    I suggest that you reproduce the error by finding some way to get “Legacy Kernel Caller” and “Requestoverride” it.



    Best regards

    Jens

    [Driver] Legacy Kernel Caller Power Manager

    Hi, thanks for your reply.

    I waited till the indexing was finished and checked CMD with the power request command to see if there was anything new. There was nothing and I proceeded to try to put my pc to rest. It woke up again sadly. Got the same issue as I got at first:

    C:\WINDOWS\system32>powercfg -requests

    DISPLAY:

    None.

    SYSTEM:

    None.

    AWAYMODE:

    None.

    EXECUTION:

    None.

    PERFBOOST:

    [DRIVER] Legacy Kernel Caller

    Power Manager

    ACTIVELOCKSCREEN:

    None.
