Soft-Off by PWR-BTTN
This field defines the power-off mode when using an ATX power supply.
The Instant-Off mode allows powering off immediately upon pressing
the power button. In the Delay 4 Sec mode, the system powers off when
the power button is pressed for more than four seconds or places the
system in a very low-power-usage state, with only enough circuitry
receiving power to detect power button activity or Resume by Ring
activity (see next field) when pressed for less than 4 seconds. The default
value is Instant-Off.
HDD Power Down
When enabled, and after the set time of system inactivity, the hard disk
drive will be powered down while all other devices remain active.
Doze Mode
When enabled, and after the set time of system inactivity, the CPU clock will
run at a slower speed while all other devices still operate at full speed.
