Sleep Manager

Most notebook computers feature built-in power-
saving functions. This computer has two power
management modes, standby and hibernation.
While standby puts your computer into a light
sleep state, hibernation shuts off all power after
saving the current state of your computer. The
next time you press the power switch, the
computer resumes from where you left off.
Sleep Manager allows your computer to perform
this function.
Note: To understand how your computer saves
and manages power, see section 2.2.
Sleep Manager is a utility that works with your
computer's BIOS and Windows APM (Advanced
Power Management) to manage the hibernation
