Shut down PC when power is drawn?

How can I set my notebook to shut down if it is no longer charged / the power to the docking station is switched off?

Maybe you can estimate the time and assign a task.

What?

If it is displayed, load another 2 hours, place the order to shut down Windows after 130 minutes.

I mean when I disconnect the power

That would work with a timer, but all storage media, including USB, can be damaged.

I think we're talking completely past each other

I want to take the power off the docking station and if that happens the laptop should shut down
