BIOS Setup
Power Management Setup
ACPI Function
This item is to activate the ACPI (Advanced Configuration and Power Management
Interface) Function. If your operating system is ACPI-aware, such as Windows 2000/
XP, select [Enabled].
ACPI Standby State
This item specifies the power saving modes for ACPI function. If your operating
system supports ACPI, such as Windows 2000/ XP , you can choose to enter the
Standby mode in S1(POS) or S3(STR) fashion through the setting of this field. Set-
tings are:
[S1]
The S1 sleep mode is a low power state. In this state, no system
context is lost (CPU or chipset) and hardware maintains all system
context.
[S3]
The S3 sleep mode is a lower power state where the in formation of
system configuration and open applications/files is saved to main
memory that remains powered while most other hardware compo-
nents turn off to save energy. The information stored in memory will
be used to restore the system when a
wake up
event occurs.
Important
S3-related functions described in this section are available only when your
BIOS supports S3 sleep mode.
