I remember seeing in the BIOS on a desktop the ability to remotely wake up a computer in hibernate or something, not sure if it works or is available on laptops.
Would this work?

Not sure if using a power line adapter for ethernet could work?

EDIT: Sorry, only half skimmed at first.
Also, is there an option if your laptop naturally goes to hibernate vs shut down?

Does this work? Not remotely though, looks like you need to be on same wifi?
