3-5 Power Management Setup
This section provides information on the Green PC power management functions. By
choosing the Power Management Setup option from the CMOS Setup Utility menu
(Figure 3-1), the screen below is displayed. This sample screen contains the
manufacturer's default values for the motherboard.
ACPI Suspend Type:
This item specifies the power saving modes for ACPI function. Available options are:
1.
S1 (POS) - The S1 state is low power state. In this state, no system context
(CPU or Chipset) is lost and the hardware maintains all system contexts.
2.
S3 (STR) - The S3 state is a lower power state, where the information of
system configuration and opened applications / files are saved to main
memory. The remaining power of other hardware components are turn off to
save energy.
3.
S1&S3 – The S1&S3 state will allow the BIOS to auto detect the
motherboard’s power saving mode between S1 and S3.The information stored
in memory will be used to restore the system when a [ wake up ] event occurs
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 Screen - 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.
