Hello! I have a late 2011 unibody MB Pro, 15", part number A1286. I believe the GPU on the logic board died - blue screen with vertical lines galore. I want to attempt and replace the logic board but am not sure of the part number. The SN of the unit is C02HL7LZDV7L and I think the proper PN for the board is 661-6081 but would like confirmation. Thanks! Update (02/01/2016) Isn’t the SN C02HL7LZDV7L? The sticker on the RAM slot says the following: SN: C02HL7LZDV7L MLB No: C02215200PGF16HA4 EMC No: 2563 Thanks.
There were actually 2 revisions for this board 661-6081 Board, Logic, 2.2 GHz, Core i7, Rev 1 661-6160 Board, Logic, 2.2 GHz, Core i7, Rev 2 Hope this helps
