Sleep Manager

Chapter 5 Software 67

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 slide the power
switch, the computer resumes from where you left off.
Sleep Manager allows your computer to perform this
function.
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 hibernation file is valid
❑saving and loading the contents of the hibernation file
when entering to and resuming from hibernation
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 was changed or the hibernation file on the
hard disk was corrupted, Sleep Manager reallocates the
hard disk space for you automatically.
Note: See “Power Management” on page 36 to understand
how your computer saves and manages power.
