Solved Hibernation not available - solved!

I was using shutdown /h in a shortcut and then I discovered that my laptop was only sleeping - the 'power on' light was flashing.

When I ran powercfg -a only S3 was available.

@zbook suggested I run powercfg /h /type full

I did this and rebooted. Hiberfil.sys is now twice the size and running powercfg -a now gives


The following sleep states are available on this system:

The following sleep states are not available on this system:
Standby (S1)
The system firmware does not support this standby state.

Standby (S2)

I have tested hibernation, and the laptop does now power off!
