How to wake a computer out of Sleep mode when AC power is restored?

I found a solution.

The four steps below will cause the PC to enter sleep mode when the UPS switches to battery. When AC power is restored, the PC will resume from Sleep. Also, should the PC's power get cut (while in Sleep mode), when power is restored, the BIOS setting ensures
it will power back on.

Step 1:

Make sure your BIOS is set to always turn the system on, should the power ever get cut. Look for "Restore Power After AC loss", or similarly named setting, and set this to On.

Step 2:

Configure the Windows power option to put the computer to sleep after X minutes. Set
Control Panel / Power Options / Put the computer to sleep: 5 minutes.

Step 3:

Change the advanced power options to also put the computer to sleep for Critical and Low battery states.

Step 4:

Under Device Manger, right click on HID UPS Battery and then under the
Power Management tab check Allow this device to wake the computer.

 

How to set Windows 11 to hibernate automatically (hibernate after)

Just to be clear, Windows has two low-power modes:

1. Sleep - All non-essential activities and drivers are stopped and the processor goes into power-conservation mode
   
2. Hibernate - The current system state is stored to hard drive, and the system powers off
   

Sleep is enabled OOTB and can be controlled by control panel.

You can enable hibernate from the advanced power settings in control panel.

In Windows 10, you can set the timeout so that after sleeping for a certain duration, the PC automatically hibernates to go to deep power saving.

Windows 11 seems to be missing the UI feature to set that time out and by default it's set to a very long time (like 16 hours)

Here's how to enable hibernate and set the timeouts by the command line.

1. Open an elevated command prompt (run as administrator)
   
2. Enable hibernate: powercfg /HIBERNATE ON
   
3. Query the current hibernate idle settings: powercfg /Q
   
   Look for a section that looks like:
   
   
   Subgroup GUID: 238c9fa8-0aad-41ed-83f4-97be242c8f20 (Sleep)
   
   GUID Alias: SUB_SLEEP
   
   Power Setting GUID: 9d7815a6-7ee4-497e-8888-515a05f02364 (Hibernate after)
   
   GUID Alias: HIBERNATEIDLE
   
   Minimum Possible Setting: 0x00000000
   
   Maximum Possible Setting: 0xffffffff
   
   Possible Settings increment: 0x00000001
   
   Possible Settings units: Seconds
   
   Current AC Power Setting Index: 0x00000000
   
   Current DC Power Setting Index: 0x00000e10
   
   0x00000e10 = 3600 seconds
   
4. To set the DC power (battery power) timeout: powercfg /x hibernate-timeout-dc 60
   
   This will set it to 60 min or 3600 seconds or 0x00000e10 seconds
   
5. You can even make it work when on AC power (plugged in): powercfg /x hibernate-timeout-ac 60
   

Why Microsoft in their infinite wisdom drops features like this I'll never no, but at least the OS can still do it.
