Chapter 3
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 feature allows user to select a suspend type for the operating system to turn off
peripherals devices, such as CD-ROM players, when they are not in use.
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].
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
