Hello .. this is my first post here but I've gotten a lot of answers to other problems in the past. So a HUGE thanks to everyone who contributes, it's much appreciated. Now .. my issue ... A friend had a spillage problem in his A1278 and I was given it to see what I could do .. after a thurough bathing it powered up again. Awesome. Now for the bad part. Whilst on the workbench before reassembly an unknown problem caused the removal of a very tiny piece which was located and then lost again, this time with no chance of finding it. My question is for anyone who knows the logic board .. what is this part that is missing ? See attached pictures for what i'm talking about. Does anyone know what is inscribed on it ? I have someone who is able to repair it but need to know what is missing. Thanks in advance for all of your help.
