PC will not sleep or shut down

[Orionaut]

So,

It Will not attempt to sleep on its own.

If I try to force sleep (By clicking on the win-Power box at bottom left of screen) it just wakes up again to the log on/PIN screen.

If I force a shutdown (As above) it goes through the shutdown sequence, powers down, and 1-2 seconds later restarts to log on screen. (To actually shut down I switch off the Power supply switch during this brief period. It does not however restart when I switch this on again later. I have to push the power button on the case as normal)

I have tried SFC/ Scanow (All OK)

Running powercfg -a Produces this result;

The following sleep states are available on this system:
Standby (S3)
Hibernate
Hybrid Sleep
Fast Startup

The following sleep states are not available on this system:
Standby (S1)
The system firmware does not support this standby state.

Standby (S2)
The system firmware does not support this standby state.

Standby (S0 Low Power Idle)
The system firmware does not support this standby state.

Running powercfg -requests generates this result;

DISPLAY:
None.

SYSTEM:
None.

AWAYMODE:
None.

EXECUTION:

PERFBOOST:

ACTIVELOCKSCREEN:

Running powercfg -lastwake generates this result;

Wake History Count - 1

Wake Source Count - 0

Running powercfg -devicequery wake_armed produces this result;

HID-compliant mouse

Running powercfg -waketimers generates this result;

Timer set by [SERVICE] \Device\HarddiskVolume5\Windows\System32\svchost.exe (SystemEventsBroker) expires at 23:45:30 on 08/12/2019.

Reason: Windows will execute 'NT TASK\Microsoft\Windows\UpdateOrchestrator\Universal Orchestrator Start' scheduled task that requested waking the computer.

And finally, running powercfg -energy resulted in an HTLM file being generated stating this (Long post so hidden in spoiler)

Platform Power Management Capabilities:Supported Sleep States

Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer to resume working quickly. Very few platforms support the S1 or S2 Sleep states.

Now, I get the impression this last info is trying to tell me something, but I am not really sure what exactly!

it used to work fine and then all of a sudden it didn't. :/

If anybody more technically compentant in these matters has any helpful sugestions to offer I would be most grateful.

 

[andicole0]

You may he better off asking on the motherboard manufacturers web forum. It sounds like Windows has lost details of the system. Have you recently updated the Bios or Windows?
Andi.

 

[DoneADougalOnSofa]

Dig around in the BIOS (usually under power/rtc config in a submenu somewhere) and make sure 'Wake on LAN' is disabled.
Probably won't be that, but worth a look.

 

[Django x2]

Out of interest, will it shutdown if you press and hold the shift key whilst clicking on shutdown?

 

[BigBoy]

sounds like the power button on your case is stuck to me...

 

[Dynix]

I've experienced exactly this in the past (PC wouldn't go to sleep or shutdown - it always started back up again) and it is/was all down to Windows. I've dug through my posts and found the "solution" which worked for me so it might be worth trying yourself:

- Open Command Prompt with Administration rights (Windows Key > type command and it should show, right click and 'Run as administrator').
- Type powercfg -requests - is anything listed? On my computer, High Definition Audio Device was always listed. Let me know if anything is listed and I'll tell you how to override it.

- Go to Device Manager and check your Network Adapters and Keyboards/Mice. Do any of them have permission to wake the computer? (Power Management tab)

- Go to Advanced Power Options. Go through the various options and see if 'Allow Wake Timers' is enabled for anything.

- Go to Local Group Policy Editor (Windows Key > Type local and it should show), then Computer Configuration > Administrative Template > Windows Components > Windows Update. Look for 'Enabling Windows Update Power Management...' and disable it.

- Go to Task Scheduler (Windows Key > Type task and it should show), then Task Scheduler Library > Microsoft > Windows > UpdateOrchestrator. Find 'Reboot' > right click Properties > Condition and untick 'Wake the computer to run this task'.

Make sure you restart after doing any of the above.

The first point - "Let me know if anything is listed and I'll tell you how to override it" - don't ask me as I have no idea 3 years on

Hope it helps.

Funny you should say that.

OK, Enlighten me.

 

[Django x2]

Funny you should say that.

OK, Enlighten me.

Holding shift during a restart or shutdown bypasses hybrid sleep. You can completely disable hybrid sleep, or see what is stopping hybrid sleep (although you've gone some way to trying to work that out). By default, W10 never shutsdown or reboots, it just hibernates for fast startup.

Well, Trying to disable hybrid sleep in control panel has no effect (Problem still ocurrs)

However Shift-shutdown does achieve shutdown.

But at least I/we seem to be getting somewhere.

What does shift-shutdown do that disabling hybrid sleep in control panel doesn't do?

And how do I did deeper to find out what is stopping everything from working properly?

Your next step would be to disable Fast Startup in the BIOS. Both Mobo and Win10 can manage hybrid sleep so if your board supports FastBoot/Startup, you want to disable it. This is only for testing purposes, although arguably, with a modern day PC, there is negligible difference to startup. It's more the programs held in cache that will be impacted.
