usually its the switch it self, the switch works by connecting a circuit on the mother board, if the switch is defective, the expansion and contraction due to heat can cause it to fire, as well as small pets or any number of other causes.

ACPI is the technical term for power options; most BIOS label it as power management or something similar.

If you know exactly which 2 pins the power switch connects to on sight, you can use any conductive material (screw driver) to momentarily bridge the 2 pins, and this will be as if you pressed the power button. I do it all the time, but I have plenty of practice, if you slip you could do some damage.

Polarity does not matter on the switch, all it does is cross the 2 pins. But make sure that the 2 are connected to the switch, I’ve seen systems that were offset by 1, which caused all kinds of hell, basically one pin from the switch was plugged in to the switch and one into the HD activity LED and it got worse from there. as for the reboot on power failure, some times this gets screwed up and it thinks it was last on and it will boot it self up. Try disabling it. the settings is something you don’t want on anyways for the most part, if you are loosing power, you will probably lose power again soon and you don’t want to lose power when the system is booting (I lost a system to this once, power flickered off, system turned back on, flickered again while it was booting up, OS was toast.)
