Power Management Setup
ACPI Function
This item is to activate the ACPI (Advanced Configuration and Power Man-
agement Interface) Function. If your operating system is ACPI-aware, such as
Windows 98SE/2000/ME, select [Enabled].
ACPI Suspend Type
This item specifies the power saving modes for ACPI function. If your op-
erating system supports ACPI, such as Windows 98SE, Windows ME and
Windows 2000, you can choose to enter the Standby mode in S1 (POS) or
S3 (STR) fashion through the setting of this field. Options are:
[S1(POS)] The S1 sleep mode is a low power state. In this state, no system
context is lost (CPU or chipset) and hard-ware maintains all sys-
tem context.
[S3(STR)] The S3 sleep mode is a lower power state where the information
of system configuration and open appli-cations/files is saved to
main memory that remains powered while most other hardware
components turn off to save energy. The information stored in
memory will be used to restore the system when a "wake up"
event occurs.
Soft-Off by PWR-BTTN
This feature allows users to configure the power button function. Settings are:
[Instant-Off] The power button functions as a normal power-on/-off button.
[Delay 4 Sec.] When you press the power button, the computer enters the
suspend/sleep mode, but if the button is pressed for more than four seconds,
the computer is turned off.
Wake-Up By PCI Card
When setting to [Enabled], this setting allows your system to be awakened
from the power saving modes through any event on PCI PME (Power Man-
agement Event).
