*Due to the sensitivity of logic-boards, all boards are returnable for "exchange" only. The board will be tested and if deemed defective by us, then the board will be exchanged only. Please be sure to pick the correct board for your model. If you are uncertain please email us with your serial number to
Replace your failed MacBook Pro Retina (2.8GHz) Logic Board with this part.
Q: How can I determine if this is the correct board to order?
A: The best way to determine this is to email us at email@example.com with your machine serial number, NOT the serial number of the logic board and sales will email you the correct part to order. You can also check your EEE code on your logic board. To be sure you are ordering the correct replacement part for your computer, make sure the EEE code of your existing logic board corresponds to one of the EEE codes listed below in notes.
EEE Code Note: All Apple logic boards have a special three digit "EEE" code embedded in the logic board serial number which positively identifies the part. Please note that this is the serial number of the logic board, NOT the serial number of the machine. The logic board serial number is on a tag which has the format "xxxxxxxEEEx". The "EEE" code is the three letters immediately preceding the last digit of the serial number.
