M2-atx hard off when turning ingnition off
Having really hard time installing my carpc. When turning the ingnition on (acc) m2-atx would start the carpc but while starting the car (ingnition on) would shut down hard. When turning off (from on to acc) again hard off instead of graceful shutdown. Works fine on bench or in the car with a simulated ingnition switch (connects to ground or +12v manually). So i figured it has something to do with the ingnition. Do get 0v in off position and +12v in acc/on. Even works if i disconnect the j3 while it's booting when starting the car. The jumpers are in p1 mode but tried other options and get the same behavior. The only thing i could think of is the automatic shut down when voltage drops below 11v, but it would not explain why it does it when turning off or why it does not when j3 is disconnected. Any help would be highly appreciated.
