Chapter 3
Video Off Option
This setting allows you to select the power-saving modes during which the monitor goes
blank.
Video Off Method
This function serves as both a screen saver and power saver for monitors. See the next
function, Video Off After, for setting the video timer.
1. Blank - BIOS will only blank the monitor's screen. The electricity saved in this mode is
negligible and this function is only used as a screen saver to prevent screen damage
while the screen is on but not in use.
2. V/H SYNC+Blank - The system turns off the vertical and horizontal synchronization
ports, writes blanks to the VGA buffer and the monitor's electron gun turns off. This
function requires a monitor with Green features in order to take advantage of the
power saving function. If you enable this function and do not have a Green monitor,
the result will be the same as if you had selected Blank. This function serves as both a
screen saver and a power saver.
3. DPMS Support - Select this option if your video card supports the Display Power
Management Signaling (DPMS) standard (i.e., you have a monitor that supports
Green features). Use software supplied by your video subsystem to set video power
management options.
Modem Use IRQ
If your computer has a modem use this function to tell BIOS which IRQ is being
occupied by the modem card. When the system is in Green mode, the modem requires an
IRQ assignment to wake up the system and perform tasks. This assignment is compliant
with APM 1.2 operating systems.
Soft-Off by PWRBTN
When set to Delay 4 Sec., this function allows the power button to put the system in
Suspend, a power saving mode. When set to Instant-Off the Soft-Off by PWR-BTN
function is disabled and the computer turns completely off when the power button is
pressed.
Run VGABIOS if S3 Resume
Available options: [Auto], [Yes], [No].
Ac Loss Auto Restart
Available options: [Auto], [On], [Off]. Please leave the default setting [Off] for a stable
system operation.
IRQ/Event Activity Detect
1. PS2KB Wakeup Select
When enabled, a PS2 keyboard hot key can turn on the system.
2. PS2KB Wakeup from S3/S4/S5
This function allows the keyboard to activate the system from S3/S4/S5 power saving
modes. Available options: [Ctrl+F1] through [Ctrl+F12], [Power], [Wake], [Any Key].
