Power Management Setup - American Megatrends Excalibur PCI User Manual

Power Management Setup

The WinBIOS Setup options described in this section are selected by choosing the appropriate high-level icon from
the Power Mgmt Setup screen. Power Mgmt Setup is selected from the Setup section on the WinBIOS Setup main
menu (see page 59). All displayed icons are described in this section, although the screen display is often all you need
to understand how to set the option.
Aux Power Off Timeout
This option specifies the length of time of keyboard, mouse, COM1, and COM2 inactivity that must expire before the
auxiliary power is shut off. Power supplies that support this feature can attach its two-wire cable to P12 and shut off
auxiliary power. The settings are Disabled and 1 Min through 255 Min in one minute intervals. The Optimal and Fail-
Safe settings are Disabled.
Monitor Low Power Mode
This option specifies the length of time of keyboard, mouse, COM1, and COM2 inactivity that must expire before the
motherboard drives the SYNC ENABLE, HSYNC, and VSYNC signals Low through open collector outputs. The 10
to 26-wire cable must be connected between P13 and the VGA adapter card feature connector. The signals on the
feature connector must not be output only. Monitors that support the display power management specification (DPMS)
will switch the power off looking at this condition, thereby saving power. The settings are Disabled or 1 Min through
255 Min in one minute intervals. The Optimal and Fail-Safe settings are Disabled.
