Well my macbook is at the service provider and they told me it will need its logic board replaced. Luckily i am in protection plan. I do have a few queries although. 1. Will my mbp retain its serial number? I know its printed on my bottom case but while in osx? 2. Does apple use refurbished boards or new ones? It would be a disappointment to have a refurbished board after spending $$$ on the protection plan. 3. My mbp is the i7 2.8 ghz late 2011 model, do they use the same board or the board of the current model i.e the mid 2012? 4. I read somewhere that a person had issues with his itunes purchases after the logic board being replaced but i could not make sure if its true? 5. Do they format the hard drive during a logic board change? The issue with the laptop was that both keyboard and trackpad were not getting detected by the system they told me that they guess both of them would need to be replaced but can only tell when the logic board arrives. Laptop history:- Display replaced Super drive replaced Magsafe Board replaced Logic Board under replacement I now feel like i may just have got a lemon?
