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 your video
subsystem to set video power management options.
D. Video Off After
This setting determines when the monitor enters power saving mode. As the
function name indicates, the monitor enters the power saving mode after the
chosen event expires. The Power Management function must be enabled to
use this function.
E. Modem Use IRQ
If your computer has an 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 requires an IRQ assignment to wake up the system and perform tasks.
This assignment is compliant with the APM 1.2 specification and is to be used
in coordination with APM 1.2 compliant operating systems.
F. Doze Mode
The Power Management function must not be set to disabled to enable this
function. If no interrupts have occured and the Doze timer expires, system will
enter Doze mode. In Doze mode, the CPU clock runs at a lower speed while
all other devices operate normaly.
@
Power saving modes achieved in lower power saving states will either be
maintained or enter higher power saving modes when switching to higher
power saving states. For example, the CPU clock will not switch back
to normal in Standby mode. It will maintain a decreased rate in Standby
Mode and turn off in Suspend Mode.
G. Standby Mode
The Power Management function must not be set to disabled to enable this
function. If the system runs in Doze mode and the Standby timer expires, the
system will enter Standby mode. In Standby mode, the hard disk drive and the
monitor shut off while all other devices still operate at full speed. Note that
the Video Off and HDD Power Down functions in Figure 3-5 provide the same
power saving options found in Standby mode. The priority for determining which
function controls power saving for the monitor and hard drive is determined
by which timer expires first.
