It saves a copy of the memory to your swap space and then turns the 
machine off.  When you turn it back on it boots up (I'm guessing it 
boots the kernel) and then restores the memory, hence why everything is 
how you left it.

I used to use Hibernate quite a lot on Windows as it was reasonably 
quick (quicker than booting from scratch) but I find on Linux it works 
out slower.  As a stop gap I generally suspend my laptop when I'm not 
using it although it does use some power to keep it suspended (whereas 
with hibernate it wouldn't use any power, well not if the machine was 
disconnected from the mains).
