I hibernate my Windows computer every time I leave it, because I see no reason to keep it running all the time, however I do want to maintain my previous running state when I resume the system.
I've noticed that there are times (and I cannot pinpoint why) my system immediately turns back on after I hibernate it. I'm aware that Hibernation is technically not "off", since things such as WoL and USB can wake the device. What I'm interested in, however, is to completely shut off the power to the system after the hibernation file is saved to disk such that the machine cannot be turned back on in any way other than the mechanical switch on the case.
Given that I'm using Windows 8.1, is there a way to accomplish this?
