On Windows, the hibernate option can be enabled and disabled from an elevated command prompt using:

powercfg -h on
powercfg -h off

It can also be automatically disabled if you've run out of disk space. The easiest way to free up some space (assuming Windows again) is to delete your System Restore history.

If it is not showing up in the power settings where you can set it.You can do a system restore, to when the service was working or if that does not work reset to factory settings after backing up everything.

(Assuming Windows) these options sometimes disappear if your graphics drivers are corrupted or missing. You check those and see if the options return.
