Hello community,

I have 5 HP Z2 G8 workstations and a problem with Windows 11 24H2. Currently, all 5 workstations have Win 10 22H2, working fine.
I did an in-place upgrade to Win 11 which worked until the first reboot. All 5 systems can't reboot or shutdown. Fans still spinning and devices never shut down. I have to press the power button for 4 seconds to power off the device, wait about 5 seconds and then can turn on the device again. Win 11 is working then but still no reboot or shutdown

 

Things I tried:
1) Updated all drivers and firmware, including latest BIOS update
2) Reset BIOS to Factory defaults
3) Tried with one device: Setup clean Windows 11 24H2 with an USB stick and even there during the OS installation rebooting the device isn't possible

 

I have older workstations with Win 11 24H2 without this problem.

All 5 workstations have certified Nvidia graphic cards.

Any ideas what to try next?
