Soft-Off by PWRBTN
Pressing the power button for more than 4 seconds forces the system to enter the
Soft-Off state when the system has "hung".
The Choices: Delay 4 Sec, Instant-Off (default).
State After Power Failure
This field determines the action the system will automatically take when power is
restored to a system that had lost power previously without any subsequent
manual intervention. There are 3 sources that provide current to the CMOS area
that retains these Power-On instructions; the motherboard battery (3V), the Power
Supply (5VSB), and the Power Supply (3.3V). While AC is not supplying power,
the motherboard uses the motherboard battery (3V). If AC power is supplied and
the Power Supply is not turned on, 5VSB from the Power Supply is used. When
the Power Supply is eventually turned on 3.3V from the Power Supply will be
used.
There are 3 options: "Auto", "On", "Off".
"Auto"
"On"
"Off" (default)
For example: If set to "Auto" and AC power is lost when system is live, then after
AC power is restored, the system will automatically power on. If AC power is lost
when system is not live, system will remain powered 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.
Disabled (default)
1Min, 2Min, 3Min, 4Min, 5Min, 6Min, 7Min, 8Min, 9Min,
10Min, 11Min, 12Min, 13Min, 14Min, 15Min.
Means to maintain the last status of the
CMOS when AC power is lost.
Means always set CMOS to the "On" status
when AC power is lost
Means always set CMOS to the "Off" status
when AC power is lost.
