No sleep, not even forced

Did you do a powercfg /requests command?
Which apps or drivers are issuing wake requests?
Hello,
Make sure your BIOS and drivers are all up to date from PC manufacturer's website.
Does it sleep immediately after you run following from admin powershell or command prompt:
More useful information: Sleep Computer in Windows 10Code:rundll32.exe powrprof.dll, SetSuspendState Sleep
Please post the response to this cmd [which can be run in a cmd or a PowerShell window]
DenisCode:powercfg -a
Yes.
The particular sleep mode that it invoked apparently defeats Wake on LAN; the machine no longer is visible.
(Later) : It was hibernation. I know it because I added item Hibernate to Start menu's Power menu, poked item, got same behavior. Notable that hibernation happens even though sleep refuses.
Note that Start menu sleep always worked until recently.
(I am uncertain about timed sleeps.)

Set it to sleep within 5 minutes for testing and see what happens. If it doesn't sleep within 7 minutes, run "powercfg /requests" to see what is preventing it from sleeping and post the output here. Or you can even run the command now to see if anything is going to prevent it from sleeping.
I already had done the time test (one minute). Also powercfg /requests; I will access and post the copied output, at next opportunity.
I would like to understand the notion of sleep prevention by wake requestors. Is the thinking that they preemptively request, as though to warn ACPI "Don't even dare think about sleep" ? Is the thinking that requests are permanent, as though on a sign pounded into the ground? Or repeated at such furious frequency that clicks in Start menu don't stand a chance of getting through? Or that they intercept and destroy initiated sleep commands in flight? We saw that they did not foil rundll32.exe powrprof.dll, SetSuspendState Sleep
If you are watching a YouTube video or listening to music, you don't want the PC to go to sleep since you are using it, even though not touching the mouse or keyboard. Also certain activities like if chkdsk was currently running will prevent the PC from sleeping - those would show up in "powercfg /requests" output - which should normally say NONE for everything if nothing is running to prevent sleep.
If I am watching or listening, and I click Sleep in Start menu, then I DO want the PC to go to sleep. And properly responding PC does so.
