    Lenovo Ideapad 320-17IKB

    Hello a customer of my brought this laptop. The laptop turns on and then quickly shuts down, sometimes the laptop turns on and charge, sometimes only turns on and does not charge, sometimes it will not power on at all. I've changed already AON7408 and AON6414A (seeing this from youtube videos) mosfets but nothing changes. AON6414A gets voltage on the left all the time on the right sides sometimes. Changing mosfets didn't help so the short must be somewhere else

      We can't help you without more informations .
      try another charger , Try another Ram .
      Give Us the voltages taken at all coils ,gives Us the voltages begore/after power button pushing.
      Give us the Impedance on all coils/jumpers checked and see if there is no short.
      visually inspect all the motherboard / IC for corrusion

      Post the schematic
