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 suspend-to-file function is activated by pressing [Fn]+[F4], the most current system status is being saved as a file on the hard disk before the notebook is being turned off. Upon waking up from suspend-to-file, the notebook would recover to exactly the same state prior to the suspend-to-file activity.
