Section 3 BATTERY POWER & POWER MANAGEMENT
3-7
Using Power Management
Note:
When running
on battery, try to
refrain from
opening too
many applica-
tions at once.
The system uses the following methods to management the
power usage of various hardware subsystems.
Windows offers two types of power management utility:
the Advanced Power Management (APM) or Advanced
Configuration Power Interface (ACPI). In the Windows
Power Management Properties (Start > Settings >
Control Panel > Power Management) dialogue boxes,
you may enter time-out values for monitor and hard disk
drive. Windows power manager saves power by turning
off hard drive after 1 minute of inactivities, for example.
Consult Windows manual for additional details on
Windows power management features.
Suspend Mode
When the battery power reaches critical low (at 3%
remaining),the system can be set to enter either one of the two
suspend modes:
Suspend
In Suspend mode, only few hardware devices, such as display
panel and hard disk, are turned off to conserve energy. The other
devices are put into low-power states.
Save To Disk
In this mode, all system data are saved in the hard disk before
powering down. When this mode is activated, you will see 3
graphic meters indicating the progress of saving data to the
disks. Once the meters reach 100%, the system is completely
shut down. No power is drawn from the battery module under this
mode. Therefore, it saves the most energy.
However, depending on how much RAM that have been installed
on your notebook, the amount of time the system requires to
restore all its previous contents can range from 15 to 30 seconds.
In order to use the Save To Disk feature, a hard disk partition is
required to store the system content. See the next few pages for
instructions on how to create a Save To Disk partition/file.
