New 661-5647 Apple Logic Board For Mac

Dec 18, 2010  It seems clear from all these posts (including mine!) that there are problems associated with both the Nvidia Graphics Chip and the Main Logic board on 3 year old MacBook Pros. It also seems to be a bit of a lottery whether Apple will repair the Nvidia piece FoC or the entire logic board.

I want to replace my logic board on my macbook pro Model Number A1278, Late 2011.

The board I want to replace has a number EMC 2555. I don´t know what this number is for. How do i find the correct apple part number. Where is and where is the MPN number located. I notice vendors on E-Bay use this number

I have another logic board it is a macbook pro model number a1278, late 2011, but is a EMC No. 2554.

Unfortunately, this board does not allow the display data cable to plug in.

Is EMC No. all I need to buy a logic board.

Thank You
