    ux32vd power failure ?

    The system goes on and after few second goes off, no short on coil, battery charge, 5v and 3v ok.
    I'm try to understand pwrgd signal to identify if there is a failure on pch.
    in the first pics the value on ux32vd board regard pwrgd signal
    in second pics a similar circuit that I have take from an asus k72 schematic to understand how this circuit work and I appreciate if someone can explain how it works
    what is the function of PM_RSMRST#PCH ?

    PM_RSMRST#PCH is a signal from SIO to wake up PCH the value of signal is low voltage=0 if the value is high PCH will never reset or wake up..
    i assuming your prolem is in PCH,mybe you should try to reball PCH chip
