hibernate/sleep stoped working

[Akadis]

Hello

I had to deactivate my gfx because it is broken and my pc gets blackscreens and so on

 

BUT I am ok with that even if the resolution isn't too fancy.

 

My Problem is that sice I deactivated i can not select it anymore (Pic1)

 

I already tried powercfg /hibernate on but there I also got an error (Pic2)

On there it says:

Error while changing to hibernate: the task is not supported

 

the change gets blocked by the following elements in the system:

-VgaSave

-hibernation got deactivated by a system component

 

I read that by installing my gfx driver it should work but then my laptop doesn't really work so is there another way to get the same result?
