Power Management Setup

ACPI Function
This item is to activate the ACPI (Advanced Configuration and Power Management
Interface) Function.
ACPI Suspend Type
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 or S3 fashion through the setting of this field. 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 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 components turn off to
save energy. The information stored in memory will be used to restore the system
when a "wake up" event occurs.
Power Management
This item is to select Power Management Function.
PME Event Function
You may disable activity monitoring of some common I/O events and interrupt re-
quests so they do not wake up the system. The default wake-up event is keyboard
activity. When On (or named, in the case of LPT & COM), any activity from one of the
listed system peripheral devices or IRQs wakes up the system. A power-manage-
ment (PM) event awakens the system from, or resets activity timers for, Suspend
mode. You can disable monitoring of common interrupt requests so they do not
generate PM events.
