Using BIOS
Power Management (User Define)
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.
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 the motherboard Wake On Modem
connector for this feature to work.
Suspend Mode (Disabled)
The CPU clock will be stopped and the video signal will be suspended if no Power Manage-
ment 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.
HDD Off When Suspend (Disabled)
This option defines if the hard disk drive is powered down when the system is put into
suspend mode.
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.
CPU THRM-Throttling (50.0%)
Use this item to specify the CPU speed (at percentage) to slow down the CPU when it reach
the predetermined overheat temperature.
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.
