IV. BIOS SOFTWARE 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 supports 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 poweroff 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 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 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. At Max Saving, these modes activate sequentially (in the given order) after one minute; at Min Saving after one hour... IV. BIOS (Power Management) ASUS TX97-X User's Manual 49
