H.5 POWER MANAGEMENT AND CONSUMPTION
This controller provides monitor power control for monitors that conform to the VESA display
power management signaling (DPMS) protocol. This protocol defines different power
consumption conditions and uses the HSYNC and VSYNC signals to select a monitor's power
condition. Table H-2 lists the monitor power conditions.

Monitor Power Management Conditions
Power Mode Description
On Monitor is completely powered up. If activated, the inactivity
counter counts down during system inactivity and if allowed to
tiemout, generates an SMI to initiate the Suspend mode.
Suspend Monitor's high voltage section is turned off and CRT heater
(filament) voltage is reduced from 6.6 to 4.4 VDC. The Off mode
inactivity timer counts down from the preset value and if allowed
to timeout, another SMI is generated and serviced, resulting in
the monitor being placed into the Off mode. Wake up from
Suspend mode is typically a few seconds.
Off Monitor's high voltage section and heater circuitry is turned off.
Wake up from Off mode is a little longer than from Suspend.
