Vista uses what is called hybrid sleep. It is a combination of sleep and
When you place the computer into sleep mode the hiberfil.sys file is also
written to. If the power goes off while you are in sleep mode (without the
hiberfil.sys active) you loose everything. If you were in the middle of a
term paper it will be gone.
With the hiberfil.sys active, if you lose power, the computer will start up
as if you had placed the computer into hibernation (instead of sleep). Your
desktop and work will be the same as when you put the computer to sleep.
It's a neat combination really and I suggest you leave well enough alone.
