IV. BIOS
(Power Management)
Video Off Method (V/H SYNC + Blank)
This field defines the video off features. Three options are available: V/H SYNC +
Blank, DPMS, and Blank Only. The first option, which is the default setting, blanks
the screen and turns off vertical and horizontal scanning; DPMS (Display Power
Management System) allows the BIOS to control the video display card if it sup-
ports the DPMS feature; Blank Screen only blanks the screen. Use the latter for
monitors that do not support the “Green” (no power management) feature. NOTE:
Screen saver software does not work with this feature. While the monitor is shut off,
this software cannot display.
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 drives.
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
sequentially (in the given order) after one minute; at Min Saving after one hour.
