! PM Control by APM — This selection, when enabled, allows operating systems with power
management support to control the modes required for safe operation of shutdown occurrences.
The default setting is Yes (Enabled).
! Video Off Option — This selection sets the conditions under which the BIOS powers down the
video (assuming your video interface supports power management).
– DPMS – Select this option only if your monitor supports the VESA Display Power Management
Signaling standard.
– H/H Sync+Blank – This options turns off the horizontal and vertical sync signals and blanks the
video buffer.
– Blank Screen – This option only blanks the video buffer.
! Power Management Timers — These timing modes are only configurable if the Power
Management option is set to User Defined. Each timer sets the amount of idle time before the
system enters the specified power-saving mode. These modes are:
– Doze Mode — This mode reduces the CPU clock speed after a set time of system inactivity, when
it is enabled. Other devices remain active.
– Standby Mode — This mode reduces the CPU clock speed and shuts down the disk drives and
video monitor after a set time of system inactivity, when it is enabled. Other devices remain
active.
– Suspend Mode — This mode shuts down all activities except DRAM refresh after a set time of
system inactivity,.
– HDD Power Down — This mode shuts down the hard disk drives after a set time of system
inactivity, when it is enabled. All other devices remain active.
– Throttle Duty Cycle — This mode selects a percentage of time the CPU runs in Doze Mode.
– PCI/VGA Active Monitor — This mode restarts the Standby Mode timer, if there is any video
activity, when enabled.
– Soft-Off by PWR-BUTTN — This mode enables the PWR-BUTTN (Power Button) input. A 4
second signal from this input will cause a power-down of all on-board systems. External power is
not controlled. The CPU fan may still run.
– Power-On by Ring (also Resume by Ring) — The mode uses a ring to power on the board, but is
Disabled by default. When power is suspended to the board, Windows shuts down and power is
removed from the ring input. This also causes the ring input to act as a startup event if a ring
occurs, which will restart the board.
– IRQ 8 Break Suspend — This mode uses the RTC Interrupt to cause the power management
mode to exit.
– CPU Fan Off in Suspend — This feature turns off the CPU Fan in suspend mode, or keeps the
fan running, allowing it to cool off the CPU.
! Reload Global Timer Events — Any of the Reload Global Timer Events will cause the Standby
Mode timer to be restarted when the event is detected.
