Note:
ACPI is a power management specification that makes hardware status in-
formation available to the operating system. ACPI enables a PC to turn its
peripherals on and off for improved power management. It also allows the
PC to be turned on and off by external devices, so that mouse or keyboard
activity wakes up the computer.
ACPI Suspend Type (S1(POS))
Use this item to define how your system suspends. In the default, S1(POS),
the suspend mode is equivalent to a software power down. If you select S3
(STR), the suspend mode is a suspend to RAM - the system shuts down with
the exception of a refresh current to the system memory.
Power Management Option (User De fine)
This item acts like a master switch for the power-saving modes and hard disk
timeouts. If this item is set to Max Saving, power-saving modes occur after a
short timeout. If this item is set to Min Saving, power-saving modes occur after
a longer timeout. If the item is set to User Define, you can insert your own
timeouts for the power-saving modes.
HDD Power Down (Disable)
The IDE hard drive will spin down if it is not accessed within a specified length
of time. Options are from 1 Min to 15 Min and Disable.
Suspend Mode (Disable)
The CPU clock will be stopped and the video signal will be suspended if no
Power Management events occur for a specified length of time. Full power
function will return when a Power Management event is detected. Options are
from 1 Min to 1 Hour and Disable.
Video Off Option (Suspend --> Off)
This option defines if the video is powered down when the system is put into
s uspend mode.
Video Off Method (DPMS Support)
This item defines how the video is powered down to save power. This item is
set to DPMS (Display Power Management Software) by default.
MODEM Use IRQ (3)
If you want an incoming call on a modem to automatically resume the system
from a power-saving mode, use this item to specify the interrupt request line
(IRQ) that is used by the modem. You might have to connect the fax/modem
to the mainboard Wake On Modem connector for this feature to work.
Soft-Off by PWRBTN (Instant-Off)
Under ACPI (Advanced Configuration and Power management Interface) you
can create a software power down. In a software power down, the system can
be resumed by Wake Up Alarms. This item lets you install a software power
down that is controlled by the power button on your system. If the item is set
to Instant-Off, then the power button causes a software power down. If the
item is set to Delay 4 Sec. then you have to hold the power button down for
four seconds to cause a software power down.
