User's Manual
E. 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.
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.
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
an electricity saver.
DPMS Supported - 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 your video
subsystem to set video power management options.
F. Modem Use IRQ
If your computer has an 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 the APM 1.2 specification and is to be used
in coordination with APM 1.2 compliant operating systems.
G. Soft-Off by PWR-BTTN
When set to Delay 4 Sec., this function allows the power button to put the
system in Suspend, a power saving mode. See Section 2-4 for operation
instructions of the over-ride power button operation wich puts the system in
Suspend mode. When set to Instant-Off the Soft-Off by PWR-BTTN function
is disabled and the computer turns completely off when the power button is
pressed.
H. HDD Power Down
The Power Management function must not be set to disabled to enable this
function. When the HDD idle time has elapsed, BIOS sends a command to
the hard disk to turn off the motor. Set a time between 1 and 15 to indicate
time required to wait before the hard drive enters a power saving mode. Some
old hard drives may not support this function.
