How can I find out what's preventing display and sleep timeouts?

    My laptop, running Windows 10 version 2004 (10.0.19041.329), is no longer able to automatically turn off its display or go to sleep. My display timeout (while on AC power) is set to 30 mins, and sleep timeout is set to 60 mins.

    After 30 mins of idle time, it turns off the display - and then turns it back on a minute or two later. This pattern then continues indefinitely, with the screen constantly turning off and then back on every few minutes. It's incredibly frustrating.

    If I manually send the computer to sleep, then it stays asleep, so apparently sleep mode itself is not a problem.

    Running powercfg -requests lists NONE in every category.
    Running powercfg -waketimers shows a few scheduled tasks, but all of them scheduled to run many hours or days in the future.
    Running powercfg -lastwake shows either that the computer never went to sleep, or the last time I woke it from a manually induced sleep.

    I've checked Event Viewer for power management events and couldn't find any indication that the computer even attempted to go to sleep, let alone woke up from it.

    It seems pretty clear that something is preventing the system from continuing to stay idle after it reaches the initial display timeout, but I can't figure out what it is.

    Any ideas? Any tools I could use to figure which apps or drivers may be interrupting the idle timer or interfering with the display/sleep timeouts?

    Take an image of all installed apps from the Control Panel / Programs & Features

    Could you elaborate? Are there specific apps that are known to interfere with idle timers?

    There could be, I wanna see what apps you have installed. for example you can take a screenshot like this:

    Run the Computer in Safe Mode to verify the issue that will tell if that is a O/S or software install problem.
