MSDOS command for hibernation

Hello.

First, to activate hibernation, the command is

powercfg -h on

And to disable it

powercfg -h off

Then you can simply create two Batch files

(files with the .BAT extension) containing this:

Hibernation_on.bat
............................................................................
cmd.exe /k
cls
@echo off
powercfg -h on
pause
exit
.............................................................................

Hibernation_off.bat
.............................................................................
cmd.exe /k
cls
@echo off
powercfg -h off
pause
exit
............................................................................

Then you just need to insert these two files into the Task Scheduler.

(Of course, do not include the dashes, it's just to separate).

You can also use the AT command

In the command prompt, type

at /?

to see all its options.

Unfortunately, I fear that this will not work to disable hibernation.
Because in hibernation, Windows is like "turned off"; only the RAM is saved, so the task scheduler will not run and the PC will not wake up from hibernation.

My question would be to find a solution to put a machine into hibernation but have it turn back on by itself at a given time.
Is it possible without Wake On Lan?
