[macfix]

Hello everybody

I m working on can not detect SSD problem macbook air 13" . Not see liquid damage sign, tested known good two different SSD, cleaned connector with degreaser solution , SSD little warming.

PP3V3_S0SW_SSD is ok
Replaced U3710 , U3711 , U3740 nothing changed

Any idea for next step?
