Chapter 3 BIOS Description
Power Management Setup
ACPI function (Default: Enabled)
ACPI stands for “Advanced Configuration and Power Interface”. ACPI is a
standard that defines power and configuration management interfaces be-
tween an operating system and the BIOS. In other words, it is a standard that
describes how computer components work together to manage system
hardware. In order to use this function the ACPI specification must be sup-
ported by the OS (for example, Windows2000 or WindowsXP). The available
setting values are: Enabled and Disabled.
ACPI Suspend Type (Default: S1(POS))
This option is used to set the energy saving mode of the ACPI function.
When you select “S1 (POS)” mode, the power will not shut off and the
supply status will remain as it is, in S1 mode the computer can be resumed
at any time. When you select “S3 (STR)” mode, the power will be cut off after
a delay period. The status of the computer before it enters STR will be saved
in memory, and the computer can quickly return to the previous status when
the STR function wakes. When you select “S1 & S3” mode, the system
will automatically select the delay time.
Soft-Off by Power Button (Default: Instant-Off)
This option is used to set the power down method. This function is only valid
for systems using an ATX power supply. When “Instant-Off” is selected, press
the power switch to immediately turn off power. When “Delay 4 Sec.” is
selected, press and hold the power button for four seconds to turn off power.
WOL (PME#) From Soft-Off (Default: Disabled)
When set to Enabled, the feature allows your system to be awakened from the
power saving modes through any event on PME (Power Management Event).
