Power Management
Power management allows the computer to save electricity when it is not in use by
entering increasingly deep power saving modes.
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 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 video subsystem to set video power
management options.
Video off In Suspend
This setting determines when the monitor enters power setting mode. If set Yes, the
monitor enters the power saving mode after the chosen event expires. The Power
Management function must be enabled to use this function.
Suspend Type
Available options: [
Stop Grant
] and [
Pwr-On Suspend
].
