2. Addition of Power On Section
The following will be added to Section 1.11.2, Front Panel Connectors:
POWER ON
This header must be connected to a front panel power switch. The switch must pull the SW_ON# pin to
ground for at least 50 ms to signal the power supply to switch on or off. (The time requirement is due to the
motherboard's internal debounce circuitry.) At least two seconds must pass before the motherboard will
recognize another on/off signal. The system will turn on for 300 ms when AC power is first applied to the
board.
CAUTION
If you need to turn off the computer during POST or because of a system lock-up, hold the power
switch in for four seconds; otherwise the computer will not switch off.
