i need a simple automatic power switch that works for all pcs. it should turn on pc again after power failure.
this function is of course in bios too but i have about 100 boards that do not switch on reliably with bios setting only.
perhaps with monostable trigger circuit or any other flip flop circuit.
the simple solution with a capcitor on power on pins do not work for my boards, because there is at least 470uF neccessary and some boards already got killed by this large capacitor. ( i als tried with resistors parallel to cap.)
pls let me know your technology suggestion when you bid.
You need a small PCB with MCU to turn on the Mother board again after power lost.
I have this board done before please check you PMB,see if it works for you.
