Windows 11 How to Enable Sleep so system powers on with saved desktop

[Abom1331 0]

Version Win11 25H2 26200.7309
Sorry long post but Complicated and I am Stuck

Hello I have three ASUS H610i-Plus-D4 based PCs with gen 12 intel i3 or i5 CPUs

All three motherboards are on F5 BIOS default settings

All three systems were build from original Win7 licenses then upgraded to win10 and last year to Win11 now at 25H2

All these system have the same working Sleep procedure I require from Sleep:
Warm Start from Sleep (System Still Powered On) Desktop Restores as was.
Cold Start from Sleep (System Powered Off) Desktop Restores as was.
Basically I can put the PC in Sleep state, Power off and when I boot in the morning they are back where they were.


So one of the system I wanted to CPU upgrade so I fitted an i5-14600 and when booted windows crashed and after a couple of tries it would not boot at all.
So after some research it was basically due to BIOS and Intel Management Engine out of date.

So I fitted the original i5-12400 gen-12 CPU brought BIOS up to latest 3810.
Then installed Win10 22H2 and latest Intel ME drive and Engine etc.
Then I let the system install all updates from MS site all the why up to Win11 25H2

So now I have a nice clean stable Win11 install with Warm Start from Sleep (System Still Powered On) working just as expected.

However, and I have tried everything I can to get Cold Start from Sleep (System Powered Off) to work.
Basically the system boots up from Sleep power on to default desktop.

---------- Clue is in the two system where Sleep recovers from power off powercfg reports: ---------

powercfg -availablesleepstates
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.

----- Rebuilt system that does not recover from power off sleep ------

powercfg -availablesleepstates
The following sleep states are available on this system:
Standby (S3)
Hibernate
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.

Hybrid Sleep
The hypervisor does not support this standby state.

-------------------------------

Basically Hybrid Sleep is missing and I have tried everything I can find on the web to fix it and nothing seems to work any ideas PLEASE.

Many thanks in advance imk

PS have been at this for two days working with Copilot and it has just looped, run out of ideas
