Different Serial Number on body case and logic board
I have a problem with my MBP early 2011 and bring it to Authorized Apple store and claim free technical services to fix GPU crash.
When they received my MBP, they scan completely and just GPU has a warning sign on MRi scan. I see on that the same SN.
But after two days, technician call me and said the SN on body case and logic board are different. But I believe, Me or my Partner never bring it to another service center (not Authorized Apple store).
Is it possible if someone change the back body case without change the Logic board SN (in case my partner lie about it).
And they said if it does not match in any way, they cannot fix MBP for free as Apple said they guarantee all GPU (AMD) problems from 2011 production.
If my MBP has ever fix on Authorized dealer, is it possible they're have the history? Similar to Medical Checkup History?
