Introducing Power Management

The Power Management feature of your notebook helps conserve
power. The followings briefly describe the features. To establish
Power Management, run the SCU program. (See "Power Menu" in
Chapter 5 for instructions.)

Automatic Power Management

Local Power Management
Local Power Management controls notebook subsystems. When a
subsystem is inactive for a period of time, called "time-out," it is
automatically shut down or slowed down to reduce power
consumption. The subsystem will be active again when next
accessed.
The subsystems under power management are:
Hard Disk Drive
Floppy Disk Drive
CD-ROM/DVD-ROM/CD-RW Drive
The above components will power down after the pre-set timing.
Global Power Management
Global Power Management automatically puts the notebook into
suspend mode when the notebook is inactive for a period of time,
called "time-out." The notebook will wake up whenever an activity is
detected (e.g. pressing a key).
The time-out settings for suspend mode can be set up in the SCU
program. The notebook suspends to RAM or disk depending on the
"Suspend Data to" setting in the SCU program.

Manual Power Management

You can manually initiate Suspend mode at any time in one of these
ways:
By pressing the hot key [Fn]+[F4].
By closing the top cover.
Note that this works only if the "Cover Close" item is set to
Suspend in the SCU program.
For information on Suspend-to-File mode, see the following section.

Suspend-to-File

When the notebook suspends to file, the system preserves all the
running application programs as a file in a "suspend-to-file partition"
on the hard disk. The notebook then turns off automatically. When
you next turn on the notebook, it reads the file from the
suspend-to-file partition back into memory, so that your notebook is
