    Powering on Lenovo Ideapad s130-14IGM without keyboard

    Hello everyone, I have a Lenovo Ideapad s130-14IGM motherboard with 32 pin JKB1 keyboard connector ( pin 31 +3V, pin 32 gnd ), but no keyboard. Does anyone know which is the pin that goes to the power button and also should be pulled low/gnd or high/+3v?
    The superIO is ITE it8987e and the pinout used for this IC on other devices suggests that pin107 (NBSWON) is for the power switch, but I can not trace that pin to any connector pin on the lenovo board.
    Thanks in advance.

          It is 130. I managed to power it up - shorted pin 31 to gnd, now starts the troubleshooting part.
