BIOS 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 W indows 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 W indows 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 main-
tains all system context.
[S3] The S3 sleep mode is a lower power s tate where the in
formation of system configuration and open applications/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 sys-
tem when a
“wake up” event occurs.
Important
S3-related functions described in this section are available only when your
BIOS supports S3 sleep mode.
