Power Management Setup

The Power Management Setup menu configures the system to most
effectively save energy while operating in a manner consistent with your
own style of computer use.
ACPI Function
Activate the ACPI (Advanced Configuration and Power Management
Interface) Function. If your operating system is ACPI-aware (i.e. Win-
dows 98/98SE/ME/2000/XP) select Enabled. Settings: Enabled
and Disabled.
ACPI Suspend Type
Set the power saving mode for ACPI function. Settings are:
S1/POS - S1/Power On Suspend (POS) is a low power state. In
this state, no system context (CPU or chipset) is lost and hardware
maintains all system context.
S3/STR - S3/Suspend To RAM (STR) is a power-down state. In this
state, power is supplied only to essential components such as main
memory and wakeup-capable devices. The system context is saved
to main memory, and context is restored from the memory when a
"wakeup" event occurs.
PM Control by APM
Specify whether the Power Management function is controled by
APM. Settings: No and Yes.
