(Power Management)
Video Off Method (DPMS OFF)
This field defines the video off features. The following options are available: DPMS
OFF, DPMS Reduce ON, Blank Screen, V/H SYNC+Blank, DPMS Standby, and
DPMS Suspend. The DPMS (Display Power Management System) features allow
the BIOS to control the video display card if it supports the DPMS feature. Blank
Screen only blanks the screen (use this for monitors without power management or
“green” features. If set up in your system, your screen saver will not display with
Blank Screen selected). V/H SYNC+Blank blanks the screen and turns off vertical
and horizontal scanning.
PWR Button < 4 Secs (Soft Off)
The default of Soft Off allows the ATX switch to function as a normal system power-
off button when pressed for less than 4 seconds. Suspend setting allows the button to
have a dual function where less than 4 seconds will place the system in sleep mode.
No Function disables the ATX switch of any functions under 4 seconds. Regardless
of the setting, holding the ATX switch for more than 4 seconds will power off the
system.
PWR Up On Modem Act (Enabled)
This allows the settings of Enabled or Disabled for powering up the computer (turns
the ATX power supply on) when the modem begins receiving or transmitting data
while the computer is off.
AC PWR Loss Restart (Disabled)
This item allows you to set whether you want your system to boot up after the power
has been interrupted. Disabled leaves your system off after reapplying power and
Enabled boots up your system after replying power.
PM Timers (Disabled)
This section controls the time-out settings for the Power Management scheme. The
fields included in this section are “HDD Power Down”, which places the hard disk
into its lowest power consumption mode, and the Doze, Standby and Suspend sys-
tem inactivation modes.
The system automatically “wakes up” from any power saving mode when there is
system activity such as when a key is pressed from the keyboard, or when there is
activity detected from the enabled IRQ channels.
HDD Power Down shuts down any IDE hard disk drives in the system after a pe-
riod of inactivity. This time period is user-configurable to 1-15 Mins or Disable.
This feature does not affect SCSI hard disks.
The Doze Mode, Standby Mode, and Suspend Mode fields set the period of time
after which each of these modes activate. At Max Saving, these modes activate se-
quentially (in the given order) after 30 seconds; at Min Saving after 40 minutes.
