How to enable hibernation on Windows Server 2019?

Question

I have Windows Server 2019. By default, hibernation is disabled. To enable it i tried:

powercfg -h on, powercfg -h -size 75%, and powercfg -h -size on.

Nothing worked. I Also tried to edit the registry:
HKLM\SYSTEM\CurrentControlSet\Control\Power

by setting HibernateEnabled to type REG_DWORD and a value of 0. That didn't enable hibernation. the command powercfg \a gives the following result:

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

    Standby (S2)
        The system firmware does not support this standby state.

    Standby (S3)
        The system firmware does not support this standby state.

    Hibernate
        The system firmware does not support hibernation.

    Standby (S0 Low Power Idle)
        The system firmware does not support this standby state.

    Hybrid Sleep
        Standby (S3) is not available.
        Hibernation is not available.

    Fast Startup
        Hibernation is not available.

How to fix that and enable hibernation?

see: [How to disable and re-enable hibernation on a computer that is running Windows (learn.microsoft.com)](https://learn.microsoft.com/en-us/troubleshoot/windows-client/deployment/disable-and-re-enable-hibernation). But with "The system firmware does not support hibernation." you need to look at superuser.com: https://superuser.com/a/1373973/421114 — Luuk, Aug 06 '23 at 07:30

To enable hibernation on Windows Server 2019, follow these steps:

Open the "Start" menu and search for "Command Prompt."

Right-click on "Command Prompt" and select "Run as administrator" to open an elevated Command Prompt.

In the Command Prompt window, type the following command and press Enter:

powercfg /hibernate on

Hibernation is now enabled on your Windows Server 2019.

You can test it by putting the server into hibernation mode using the usual hibernate method (such as selecting "Hibernate" from the Start menu). To wake the server from hibernation, press the power button or any other designated wake-up key.

Please note that hibernation may consume disk space equivalent to the amount of RAM installed on your server, as it saves the system state to the hard drive. Ensure that you have sufficient disk space for hibernation to function properly.
