Anyone know what this component is?

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. :)

You can obtain schematics on internet via googling 820-3115B which is the board number for the MacBook Pro 13" mid-2012 logic board.

Board view files arw also obtainable which openboardview can open that file for you.
