Windows 11 Desktop PC with Prime Z690-A will not sleep

[Old_NZ_Parkie]

Hi,

Our desktop PC appears to be functioning normally, but it will not sleep. The dual screens switch off after 5 minutes (as set) and the PC tries to sleep after 10 minutes (as set) but immediately kicks back into life.

Our desktop PC is a 64 bit PC running Windows 11 Home vsn 23H2 OS Build 22631.2861. It has the 12th Gen Intel Core i7-12700K CPU with 64GB of DDR5 memory (four x 16GB G.SKILL Trident Z5) and the Intel UHD Graphics 770.

Our Motherboard is a Prime Z690-A with 2802 BIOS installed and the Intel ME is vsn 16.1.30.2307.

In the BIOS under Advanced à Advanced à Onboard device Configuration the “USB Power Delivery in Soft Off State (S5)” is set to Disabled and the LED Lighting “When System is in sleep, hibernate or soft off states” is set to Aura Off.

I have used the ASUS utility to uninstall Armoury Crate as I thought this may be causing the problem.

I have reset the windows 11 power plan and then set it to balanced with the advanced power option for the Sleep wake timer set to disabled - the PCI Express Power management set to off and the multimedia setting when sharing media set to “Allow the computer to sleep”.

By running the Command Prompt Powercfg /availablesleepstates I’ve confirmed that Standby (S3) is the only sleep state available on the PC.

By running the Command Prompt Powercfg / waketimers I’ve confirmed that there are no active wake timers running on the PC.

By running the Command Prompt Powercfg -requests I’ve confirmed that there are no processes preventing sleep.

By running the Command Prompt Powercfg /requests I’ve confirmed that there are no USB controllers that are preventing our PC from going to sleep.

What else should I try?

Thanking you in advance for your help, Dave

Additionally - If I select  sleep from the power menu (Start --> Power --> Sleep) the same problem occurs - the PC tries to sleep and immediately kicks back into life

Maybe take a look at wake on LAN options as well. If you are using ethernet, perhaps one of those settings is responsible.

Hi, thanks for the suggestion. 

Using Device Manager I have set Disabled the “Wake on Magic Packet”, “Wake on Magic Packet From S5”, “Wake on Pattern Match” and “Allow this device to wake the Computer” for the Intel Ethernet Controller.

In the BIOS I have run the Memtest86 memory test tool and it didn’t find any issues.

And now our PC has gone into sleep mode 3 times!

Many thanks, Dave
