Using Power Management
The system provides you with various modes to manage its power
consumption while maintaining system performance. Please refer to
Chapter 3: BIOS Utilities, System Configuration Utility, Power Menu for
more information.
Advanced Power Management (APM 1.2)
The system provides built-in Advanced Power Management (APM 1.2)
support to reduce power consumption. APM function varies depending on
the operation system you are using.
Some operation systems do not
support APM, such as Windows NT, and therefore, cannot take
advantage of the system’s capabilities in this area.
Advanced Configuration and Power Interface
(ACPI)
The ACPI interface gives the operation system (OS) direct control over the
power management and Plug and Play functions of a computer. The
operation system can perform the functions covered by the ACPI
specification, such as system power management, device power
management, and thermal management.
Global Standby
In Global Standby mode, the CPU clock will be stopped and most
controllable peripheral devices will be power off. If the idle timer expires
before any system activity is detected, the system will change from
Standby mode into Suspend mode.
Hard Disk Standby
The system will turn off the computer’s hard disk drive motor if it has not
been accessed after a specified period of time. The motor will be turned
back on if the system attempts to read or write data to it.
