ACPI Suspend Type [S3(STR)]
Use this item to define how your system suspends. In the default, S3 (STR), the
suspend mode is a suspend to RAM, i.e., the system shuts down with the exception
of a refresh current to the system memory. If you select S1 (POS), the suspend
mode is equivalent to a software power down.
Run VGABIOS if S3 Resume [Auto]
This item allows the system to initialize the VGA BIOS from S3 (Suspend to RAM)
sleep state.
Video Off Method [DPMS]
This item defines how the video is powered down to save power. This item is set to
DPMS (Display Power Management Software) by default.
Video Off In Suspend [Yes]
This option defines if the video is powered down when the system is put into suspend
mode.
Suspend Type [Stop Grant]
If this item is set to the default Stop Grant, the CPU will go into Idle Mode during power
saving mode.
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 motherboard Wake
On Modem connector for this feature to work.
Suspend Mode [Disabled]
3-14
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.
HDD Power Down [Disabled]
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.
Soft-Off by PWR-BTTN [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.
Resume by PCI PME [Enabled]
This item specifies whether the system will be awakened from power saving modes
when activity or input signal of the specified hardware peripheral or component is
detected.
Resume by Ring [Disabled]
An input signal on the serial Ring Indicator (RI) line (in other words, an incoming call on
the modem) awakens the system from a soft off state.
Resume by USB(S3) [Disabled]
This option allows the activity of the USB devices (keyboard and mouse) to wake-up
the system from S3 sleep state.
