Doze Mode
After the selected period of system inactivity, the CPU clock
throttles to a small percentage of its duty cycle — between 10
percent and 25 percent for most chipsets. All other devices still
operate at full speed.
Suspend Mode
After the selected period of system inactivity, the chipset enters a
hardware suspend mode, stopping the CPU clock and possibly
causing other system devices to enter power management modes.
HDD Power Down
After the selected period of drive inactivity, any system IDE
devices compatible with the ATA-2 specification or later power
manage themselves, putting themselves into an idle state after the
specified timeout and then waking themselves up when accessed.
MODEM Use IRQ
Name the interrupt request (IRQ) line assigned to the modem (if
any) on your system. Activity of the selected IRQ always awakens
the system.
Throttle Duty Cycle
When the system enters Doze mode, the CPU clock runs only part
of the time. You may select the percent of time that the clock runs.
Soft-Off by PWR-BTTN
When you select Instant Off or Delay 4 Sec., turning the system off
with the on/off button places the system in a very low-power-
usage state, either immediately or after 4 seconds, with only
enough circuitry receiving power to detect power button activity or
Resume by Ring activity.
