    M2-ATX shutdown question

    So I've just installed my M10000 and I'm using an M2-ATX power supply. Everything seems to be working correctly in the beginning. I turn on the car and about 5 seconds later the system powers up. Then I turn off the car and about 5 seconds after the car is off, the M2 turns off completely, no nice shutdown of Windows. I have the MB power signals routed to the J8, and like I said it works to turn on OK. It's the hard off instead of shutting down that is odd. The timing jumpers are set to "B". In Windows, the power option is set to "power off" the when the power buton is pressed.

    Any ideas what this could be? Thanks!

    How is your M2-ATX wired to your car's electrical system? Do you have the +12vdc lines reversed? If you're using MODE 1, it should be shutting down fine. I use Hibernate in windows, but the M2 sends the hibernation signal 5 seconds after I turn the car off, and then shuts down completely after 45 seconds. If the power lines are reversed it would (I think) turn on just fine, but the power off would be a hard off as you would be cutting the power immediately.

    I second the reversed +12constant and +12ignition.

    Sounds like a classic problem.

    Just got another chance to work on it. Makes sense what you guys said, but I checked and everything works as it should. The line going to J1 is always on (battery +) and the line going to J3 turns on after I turn the ignition. These are all with reference to J4 (gnd).

    Anyways I fixed it by making one of my buttons trigger the Windows shutdown. I'm just using a character LCD and keypad interface. It works and I'm happy, I'll have to post my pictures when I get a chance. Thanks for the help!

    Cause MODE A does not have any timing, start up or shutdown services.

    What MODE are using based on the Jumpers. Your BIOS is probably set to start the computer upokn power application, so once the M2 powers the ATX connector, it starts up, no matter what happens with the button.

    It is not shutting down properly because your J8 wires are not hooked to the MB ACPI header correctly, or you have a positive switch (not likely).

    Alright, I unhooked the J8 wire from the motherboard and turned the key, the system did not boot. i turned the key off and hooked up the wire to the board, turned the key and 5sec later it booted up.

    The wires should be hooked up correctly to the header unless positive and negative matter, which as far as i know they shouldnt.

    I'll have to check the BIOS again but i'm pretty sure there are no power options.
