System unable to hibernate after update
4.5
Hibernation fails or the hiberfil.sys file is deleted/corrupted after an update.
Symptoms
- "Hibernate" missing
- PC crashes when hibernating
- Slow boot
Possible Causes
- Hibernation disabled by OS
- Insufficient disk space
- Incompatible chipset driver
Step-by-Step Fix
1
Re-enable Hibernation
Run "powercfg -h on" in an elevated Command Prompt.
2
Check Disk Space
Hibernation needs space equal to about 75% of your RAM.
3
Update Chipset Drivers
Ensures the OS can correctly signal the hardware to enter a deep sleep state.
When to See a Technician
Major updates often disable hibernation to prevent "resuming" into a mismatched system state.
