    M4atx power modes problem

    i just installed the m4atx in my machine. the problem i am facing is with the dip switch modes. in the standard psu mode (p0) it power on the computer, when i change the mode to work it with the ignition (p1 or p2), it doesnt power the mother board. the light on the psu blinks (its different in the p0 mode) at a regular interval but it seems its not sending the power to the motherboard. what could be the problem?

    is there an error code writeup for this psu? may be something to tell what the blinking light means?

    If you disconnect the m4 from the power switch header and manually switch the motherboard on does everything power up? (this would indicate the m4 is powering on all the rails, just not firing the motherboard on pulse)

    The power on connector has polarity, so make sure it is the right way round. (In other words, if it don't work take it off and turn it 180 degrees and try again)


    Also the M4-ATX has to be getting no power when you change the DIP switches.


    Also have you had a read of this thread

    yes this works fine... only when the dip switch is used and the connection is there from the motherboard on/off jumper, it doesnt work.

    i was not aware of the polarity of the on/off switch will try it and see what happens (i think i tried it but dont remember exactly.. was trying all the possible combinations)

    i know if should not be connected to the power source which changing the dip switch but is there some time gap i should use for connecting the power back?

    also can you tell me if i can buy this http://robokits.co.in/shop/index.php...products_id=57 and use it to flash the firmware? my electronics is as bad as my luck
