Windows 10: Windows 11 Sleep turns into abruptly shutdown most of the times

Windows 11 PRO, 23H2In the last couple of weeks, my PC is acting up only 1 year old. The sleep function from window idle after a few minutes, or power->sleep menu turns into an expected shutdown blank screen, shutdown, no sign of anything like normal sleep entry. This happens 9 out of 10 times. Not every single time. Only thing in event log was "the previous system shutdown at xxx was unexpected".Update BIOS, windows to latest already, restored power scheme to default etc. No differences. Nothing else is out of ordinary. Windows runs fine otherwise. Anyway to debug this? I can't find

:)

 

Reminder: Microsoft Windows 7 Beta Automatic Two-Hour Shutdowns Begin Today

Does that work?

 

Surface abruptly shuts down when screen off or sleep  

I confirm that without Power service from msconfig I solved the problem! And I tried to reactivate Power service and... here there is again the shutdown! These are the settings before with the shutdown problem:



These after, without Power service loaded, with NO shutdown:





I'm happy I can finally use the pc without the fear to not make any input. But anyway, is it possible to restore original Power service and settings without the shutdown problem?

HDtune SD: I don't make the health it's a 1TB SD: infinite time...

Tomorrow I'll see OCCT - - - Updated - - - *************** EDIT 21/12 Now this pc is really unusable!! Weeks ago there was only a shutdown when I closed the lid after going to sleep. Now I get random shutdown also when no input for less than 30s!! Too much instable, really unusablem, I fear leaving the touchpad or the keyboard!! 21/12 10:09 shutdwon <30s noInput (on battery, battery still 100%, power mode on battery reduced, screen on, no sleep, only program active: VScode active) 21/12 11:20 shutdwon about 3m noInput (on battery, battery 70%, power mode on battery reduced, screen on, no sleep, only program active: Explorer) 21/12 15:52 shutdwon <30s noInput (on battery, battery still 100%, max power mode, screen on, no sleep, only program active: Explorer) 21/12 15:54 shutdwon after 12s (!!) noInput, no keyboard attached (on battery, battery still 100%, max power mode, screen on, no sleep, only program active: Explorer) 21/12 17:45 shutdwon after 1m noInput, no keyboard attached (on battery, battery 48%, power mode on battery reduced, screen on, no sleep, only program active: Explorer) Here OCCT results, all normal... I think it's the opposite of a stress problem I never had a shutdown when there is activity on the pc... The problems arise only when the pc has no external inputs (or maybe low CPU occupation?) or battery related problem (but I got also with direct plugged in cable, BUT NEVER had a problem with USB-C + plugged .... ??? ):
