Note
The term 'AC power loss' stands for the state when the module looses the standby voltage on the 5V_SB pins. The standby voltage is
continuously monitored after the system is turned off. If the standby voltage is not detected within 30 seconds, this is considered an AC power
loss condition. If the standby voltage remains stable for 30 seconds, it is assumed that the system was switched off properly.
Inexpensive ATX power supplies often have problems with short AC power sags. The system turns off but might not switch back on, even
when the PS_ON# signal is asserted correctly by the module. In this case, the internal circuitry of the ATX power supply has become confused.
Usually, a AC power off/on cycle is necessary to recover from this situation.
