A1466 - How to identify the Logic Board

In looking to repair an Air, I have determined that somehow someway a liquid got inside the case. It does not charge at all. No green light.

Bought a new battery and installed it, but that did not solve the issue.

So … is this an I/O board issue? Was the logic board fried? How can I identify the specific model of the logic board or the laptop itself? One of the capacitors is marked as “4R7 433 5AM” below what I believe is the wireless card.

Thanks in advance for the reply.

Thanks. I did not look closely enough. That site is a great tool!

Now … time to determine how much this will cost me to repair :-)

The easiest method would be to look up the serial number on the back case of the laptop. Powerbook medic has a search tool for it.
