800 G4 on Win 11 will not wake up from sleep after BIOS update

[Marninger]

Hello

After resent BIOS update to my HP EliteDesk 800 G4 I can no longer wake it  up from sleep using the keyboard / mouse / button or WOL magic packet.

I have searched for and tried every advice I have been able to find here or at Microsoft, - but so far not been able to resolve this, now I hope somebody here can help?

I have checked for updates from Microsoft and using HP Assistant, - but everything already seems to be up to date.

System information from HP tool:

Here are some of the things I've tried:

In Device Manager I've made sure the Keyboard, Mouse and Network adaptor may waken the computer. I've also enabled this for any and all USB devises (as keyboard and mouse are connected that way), and for all HID devices.

In the BIOS I've enabled the keyboard to wake the computer.

In Energy settings I have set it to always on and at full power, - yet it rather quickly goes into some kind of sleep mode?

.  . . . I just tested also disabling the screen to be turned of, - and it seems that enables the computer to stay on!

I don't consider this as a fix but it will help further testing, - and I found i now can put it to sleep, and then wake it from power button and from the keyboard.

Hi WAWood,
Thanks for reaching out, unfortunately I've already tried the suggested steps in the video, - to no avail.
