Power Management Setup
The Power Management Setup allows you to configure you system to most
effectively save energy while operating in a manner consistent with your own
style of computer use.
IPCA 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. Settings: Enabled and Disabled.
ACPI Suspend Type
This item specifies the power saving modes for ACPI function. Options are:
S1 (POS) The S1 sleep mode is a low power state. In this state, no
system context (CPU or chipset) is lost and hardware
maintains all system context.
S3 (STR) The S3 sleep mode is a power-down state in which power
is supplied only to essential components such as main
memory and wake-capable devices and all system con-
text is saved to main memory. The information stored in
memory will be used to restore the PC to the previous
state when an “wake up” event occurs.
S1 & S3 Both S1 & S3 modes will be adopted.
