Check if Hibernation works

If you’re not sure if Hibernation works as planned I might have created a Solution for you!

A Script that monitors all interaction of a User with a Notebook. Starting the Script will set a counter to T + 15 Minutes (or whatever you configure) if no one touches the Device and the Device is set to Hibernate after 15 Minutes the Script should log the Hibernation Process and proof that Hibernation is working.

	.DESCRIPTION
		This Script monitors the Interaction of the User via Mouse, Keyboard and 
		Touch with the Notebook. If any interaction happened the Timer will be reset. 
		The Script should show you if Hibernation works as planned!
