Power Management Functions - Compaq Armada 100 Maintenance And Service Manual

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 Local 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 timeout 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.
AMD PowerNow!
NOTE: This power mode is available only on the Compaq Notebook 100
Personal Computer.
Processor clock speed and voltage are automatically reduced based on an
AMD proprietary weighted average. The "High Performance,"
"Automatic," and "Battery Save" modes can be set up and switched
based on the power source to allow you to customize system
performance and battery life.
