Hibernate is missing from the power menu

Troubleshooting guideSources checked: 2026-09-05FaultNote editorial team

What to do first

Hibernate is missing from the power menu. Hibernation may be disabled, free space may be insufficient for hiberfil.sys, or firmware/drivers may restrict available sleep states. Record the current state before changing it, use only the supported Windows path described below, and verify the same operation again after any required restart.

This is a general troubleshooting guide, not an announcement of a current outage.

Affected products and symptoms

Product: Windows power management
Versions and conditions: Windows 11 (confirm the edition and hardware requirements for the feature)
Error codes and identifiers: powercfg

Symptoms

Hibernate is missing from the power menu.
The same condition can persist after a retry or restart.

Causes and conditions

Hibernation may be disabled, free space may be insufficient for hiberfil.sys, or firmware/drivers may restrict available sleep states.

Before you start

Save open documents and allow time for a Windows restart if required.
Run administrative actions only on a personally managed PC or with administrator approval.
Save the diagnostic command output so the before and after states can be compared.

Precautions

Do not bulk-delete registry entries, system folders, credentials, or storage metadata.
Do not run unofficial scripts or unknown drivers with administrator rights.

Step-by-step instructions

01
Distinguish hibernation from sleep
#
Hibernation saves memory contents to the system drive before powering down. Separate a hidden Start > Power entry from a state reported as unavailable by powercfg. Check free space on the system drive as well.
02
Check the state with powercfg
#
In an elevated terminal, check the available sleep states and the reason hibernation is unavailable.
Command or path
```
powercfg /a
```
03
Repair through the supported path
#
If hibernation is merely disabled, enable it with powercfg, then open Control Panel > Power Options > Choose what the power buttons do and make Hibernate visible.
Command or path
```
powercfg /hibernate on
```
04
Show Hibernate in the power menu
#
Under Choose what the power buttons do, select Change settings that are currently unavailable, enable Hibernate under Shutdown settings and save. If powercfg /a reports a hardware or other restriction, repeatedly changing the menu setting will not resolve it.
05
Verify under the same conditions
#
Run powercfg /a and repeat the original operation once under the same conditions. If it succeeds, verify again after a restart and record the setting that changed.
Check that no new critical event with the same timestamp and component appears in Event Viewer.
Command or path
```
powercfg /a
```

Check the result

The feature starts, connects, or completes without the original error.
The verification command reports the expected enabled, healthy, or connected state.
The result remains correct after a Windows restart and no new matching critical event appears.

If the problem continues

If the same code persists, provide the full message, Windows build, command output, and occurrence time to the PC administrator or Microsoft Support.
If hardware requirements, organization policy, or server settings are responsible, ask the owner to make the change instead of bypassing it on the client.

Scope of this guide

Troubleshooting guide — Restore the feature so it starts, connects, or completes normally and passes the same verification after a Windows restart.

Frequently asked questions

Does enabling hibernation consume disk space?

Yes. Windows creates hiberfil.sys on the system drive, so ensure sufficient free space first.

What if powercfg /a says firmware does not support it?

Windows settings cannot add firmware support. Check the PC manufacturer's UEFI and driver guidance.
