Power Management Option (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.

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.

This option defines if the video is powered down when the system is put into suspend

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.
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.
