1.3 Power Management Functions
Power Management functions of the computer are designed to conserve
power. All Power Management functions can be configured from the
Setup Configuration Utility (SCU), described later in this chapter.
Automatic Power Management
Automatic Power Management operates at two levels as described in the
following paragraphs.
Local Power Management
Local Power Management controls computer subsystems. When a
subsystem is inactive for a period of time, it is automatically shut down
or slowed to reduce power consumption. The subsystem returns to an
active state when it is accessed.
Subsystems under Power Management include:
Hard disk drive
Diskette drive
CD-ROM drive
LCD display panel
Global Power Management
Global Power Management automatically puts the computer into Suspend
mode when the computer is inactive for a period of time. The computer
wakes up whenever activity resumes.
The time-out settings for Suspend mode are set up in the SCU program.
The computer uses Suspend-to-RAM (Standby) or Suspend-to-Disk
(Hibernation) depending on the Suspend Data To setting in the SCU
program.
Manual Power Management
Suspend mode can be initiated at any time in one of two ways:
By pressing Fn + F12.
By closing the top cover, if the Cover Close option is set to Suspend
in the SCU program.
