OWNER’S HANDBOOK 5/9
In standby mode, the motherboard can reduce power consumption
by spinning down hard drives, and reducing power to or turning off
VESA DPMS-compliant monitors. Power-management mode can
be enabled or disabled in Setup.
While in standby mode, the system retains the ability to respond to
external interrupts and service requests, such as incoming faxes or
network messages. Any keyboard or mouse activity brings the
system out of standby mode and immediately restores power to the
monitor.
The BIOS enables APM by default; but the operating system must
support an APM driver for the power-management features to
work. For example, Windows 95 supports the power-management
features upon detecting that APM is enabled in the BIOS.
Advanced Configuration and Power Interface (ACPI)
ACPI gives the operating system direct control over the power
management and Plug and Play functions of a computer. ACPI
requires an ACPI-aware operating system. ACPI features include:
Plug and Play (including bus and device enumeration) and
APM functionality normally contained in the BIOS
Power management control of individual devices, add-in
boards (some add-in boards may require an ACPI-aware
driver), video monitor, and hard disk drives
Methods for achieving less than 30-watt system operation in
the Power On Suspend sleeping state, and less than 5-watt
system operation in the Suspend to Disk sleeping state
A Soft-off feature that enables the operating system to power
off the computer
Support for multiple wake up events
