What is the difference of the Autoshutdown Plugin Explanation of "Shutdown command"

Hello,

I currently use the "Shutdown" command when no device is moving in my network and the server should then go to sleep. When I need the server, I wake it up via WLAN and a WOL command.

What is the difference to the other commands in Autoshutdown Plugin? (Hibernate, Suspend, Hybrid sleep, Suspend then Hibernate)
