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 XP, you can choose to enter the Standby
mode in S1(POS) or S3(STR) fashion through the setting of this field. Settings 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.
