Hi, good day!
- Do you use a personal or office computer?
- Have you tried the AI suggested solutions?
- Could you check one of the PCs and tell me the Windows version/build (winver)?
Open and run Command Prompt as administrator
Copy and paste the command below then press Enter
powercfg /a
If it says hibernation is unavailable, that explains why the setting vanished.
I look forward to receiving your update and I'm willing to collaborate with you till we resolve the issue. Do keep me informed by clicking "Add comment" below instead of Yes or No button.
