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
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 or
not after the power has been interrupted. After power is restored, Disabled
leaves your system off and Enabled boots up your system.
PM Timers (Disable)
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 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 period 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: 30 sec, 1 Min, 2
Min, 4 Min, 8 Min, 20 Min, 30 Min, 40 Min, 1 Hour.
