PWRON After PWR-Fail
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 on 3.3V from the Power Supply will be used.
There are 3 options: “Former-Sts”, “On”, “Off”.
“Former”
Means to maintain the last status of the CMOS when
AC power is lost.
“On”
Means always set CMOS to the “On” status when AC
power
is
lost.
“Off” (default)
Means always set CMOS to the “Off” status when AC
power
is
lost.
For example: If set to “Formar-Sts” 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.
