How to find MacBook Pro Logic Board Part Number. I want to replace my logic board on my macbook pro Model Number. Machine by using your serial number.

I recently had the Logic Board in my Retina MBP 15″ 2012 replaced under a warranty extension program and Apple paid for it. I've reinstalled OS X several times and feel things aren't running properly. Also, I also couldn't find a way to merge my Time Machine old backups with new one. The problem I have is confirming that I actually got a new board installed. I have not found a way to confirm this. My Mac help isn't helpful and Google is even less helpful. Why is it so hard to confirm that new hardware is really installed after this repair?

You can compare the serial number on the bottom of the laptop casing to the serial number shown in System Report by going to Apple Menu ->About This Mac. When I worked at Apple, it was known that replacement logic boards would carry the new SN (naturally) and that cases from the old SN would link to the new one. The serial on the laptop itself is the original SN it shipped with (unless the bottom case has also been replaced) and can be found in very small print near the display hinge.

However, the Time Machine change makes me conclude you have a new board. You could try dumping the hardware identity from the Time Machine backup directory: xattr -p com.apple.backupd.BackupMachineAddress /Volumes/yourBackupDrive/Backups.backupdb/yourMacName Since you paid for the repair, Apple should walk you though re-joining the Time Machine over the phone or via internet chat for free post repair. Did you have it serviced via mail in or at an authorized service provider or at a genius bar? The steps to get repair details can change a little - but you could start by calling AppleCare and asking them to read the technician notes that were left by the repair tech. There should be time stamps when it started repair - possibly a list of parts used, probably some test results they ran, etc. Usually a logic board has it's own internal serialization, but you need to open the hardware to see that or have knowledge of revisions on the boards.
