You are right in that most PCs do, in fact, draw a small charge to supply the mobo with enough power to support certain functions - e.g. Wake-on-LAN - but it is not a requirement for Hibernation.
I know this from personal experience - I have put a laptop into hibernation, unplugged it and removed the battery; it still resumed from the point of hibernation when I powered it up again.
Go try it yourself!

Hokay... same tune, different hymnsheets. Yup, I agree that my lappy doesn't require / draw power when hibernating... but all my desktops since about 2000 have, and I ain't found no way of switching that off, even in the BIOS, except by using that wall switch in the kneehole of my desk.
And yes, of course, I agree: switching off at the wall doesn't affect any of the hibernated files - overnight or for ten years, I would guess.
Anyway, watts a couple of whats between friends?
