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 li ght sleep s ta te, Hib er nat ion shu ts of f all
power after saving the current state of your computer. The next time you slide the
power switch, the computer resumes from where you left off.
Sleep Manager allows your computer to perform these power-saving functions.
Note: See “Power management” on page 36 to understand how your
computer saves and manages power.
Sleep Manager is a utility that works with your computer’s BIOS and Windows
APM (Advanced Power Management) to manage the Hibernation operation. This
includes:
• creating the Hibernation file which contains the current state of the computer
• checking if the Hibernatio n file is valid
• saving and loading the contents of th e Hiber na tion f il e whe n en teri ng i nto and
resuming from Hibernation mode
The Hibernation file resides in a contiguous area on your hard disk.
Sleep Manager can automatically create, recover, and reallocate space for the
Hibernation file. If the system memory size changes or the Hibernation file on the
hard disk is corrupted, Sleep Manage r reallocates the hard disk space for you
automatically.

The computer automatically loads Sleep Manager every time you start
Windows. Sleep Manager resides in the background and the Sleep Manager
