I had a customer bring in a water damaged macbook pro and I told them the water damage had corroded a component on the logic board. I don’t think they want the device anymore so I was going to attempt to replace this component if possible, but I dont know what it is or have any diagrams or schematics. The component says “KNP” vertically and “AO” horizontally. :)
That is Q4262 a dual MOSFET package BSS8402DW
