Video Off Method (DPMS OFF)

This field defines the video off features. These 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 (or 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.

PM Timers

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 system 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 (Disable)

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 disks.

Doze Mode, Standby Mode, Suspend Mode (Disable)

These 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, and Disable.

Power Up Control

This section determines the ways the system can be controlled when it is started or restarted, when modem activity is detected, or when power to the computer is interrupted and reapplied. The Soft-Off mode refers to powering off the system through a momentary button switch (ATX switch) or through the software as opposed to disconnecting the AC power by way of a rocker switch or other means.

PWR Button < 4 Secs (Soft Off)

When set to Soft Off, the ATX switch can be used as a normal system power-off button when pressed for less than 4 seconds. Suspend allows the button to have a dual function where pressing less than 4 seconds will place the system in sleep mode. No Function disables the ATX switch function when the button is pressed under 4 seconds. Regardless of the setting, holding the ATX switch for more than 4 seconds will power off the system.
