So recently I had repairs done to my MBP. They changed out my logicboard. The tech did something really weird and put in a logic board with the upgraded processor and upgarded video card. I was pretty excited about it. Today I was checking my serial number on my computer and realized the one printed on my computer is different than the one showing up in my system profiler. I also noticed that the serial number that shows up in my system profiler has apple care protection on it. I never purchased applecare, and so naturally, the serial number printed on the computer does not have applecare on it. I'm concerned about this discrepency in serial numbers because I'm unsure as to what will occur next time I take it into to get it worked on. Anyone have any recommendations? Oh, one other piece of information. The reason this sounds like a very untraditional repair is because the tech who worked on my computer was an apple certified technichian on the campus of the school I go to.
