Description
This item is to activate the ACPI (Advanced
Configuration and Power Management Interface)
Function. If your operating system is ACPI
aware, such as Windows 98SE/2000/Me, select
Enabled.
This item specifies the power saving modes for
ACPI function. 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 s power-down state in which power is
supplied only to essential components such as
main memory and wake-capable devices and all
system context 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.
This option is used to set the power down
method. This function is only valid for systems
using an ATX power supply. When ""nstant off" is
selected, press the power switch to immediately
turn off power. When "delay 4 sec" is selected,
press and hole the power button for four seconds
to turn off power.
Use this item to enable or disable a power
management scheme. If you enable power
management, you can use this item below to set
the power management operation.
