Power Management
You can manage power consumption while maintaining system performance
by setting your computer to one of the available power management modes.
Information on the various types of power management are listed below. If you
want information on how to set the power management options please refer to
the Power Menu in this chapter.
Advanced Power Management (APM 1.2)
To reduce power consumption, the system provides built-in Advanced Power
Management (APM 1.2). The APM function varies depending on your operating
system (OS). Some operating systems, such as Windows NT do not support
APM.
Advanced Configuration and Power Interface
(ACPI)
The ACPI interface provides the computer with enhanced power saving
techniques and gives the operating system (OS) direct control over the power
and thermal states of devices and processors. For example, it enables the
OS to set devices into low-power states based on user settings and informa-
tion from applications.
Global Standby
In the Global Standby mode, the CPU clock will stop and various controllable
peripheral devices will be powered off. If the idle timer preset in the BIOS Setup
Utility expires before any system activity is detected, the system will enter the
Suspend mode from the Standby mode.
Hard Disk Standby
The computer's hard disk drive motor will be turned off if the hard drive has not
been accessed for a specified period of time. If the system reads or writes data
to the hard disk, the motor will be turned back on.
