selected Blank. This function serves as both a screen saver and an electricity
saver.
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.
E. 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
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. Soft-Off by PWRBTN
When Enabled, this function allows the power button to put the system in Suspend,
a power saving mode. See section 2-4 for operation instructions of the power
button.
G. HDD Power Down
To enable this function, make sure the Power Management function is not set
to disabled. When the HDD idle time has elapsed, BIOS sends a command to
the hard disk to turn off the motor. Set a time between 1 and 15 to indicate
time required to wait before the hard drive enters a power saving mode. Some
old hard drives may not support this function.
H. Doze Mode
To enable this function, make sure the Power Management function is not set
to disabled. 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.
I. Suspend Mode
To enable this function, make sure the Power Management function is not set
to disabled. If the system runs in Dozemode and the Suspend timer expires, all
devices regulated by power management will shut off and the CPU speed will
be 0 MHz.
