Hello All, I bought an 2010 MBP 17 i7 from eBay which was advertised to have an Applecare plan until Dec 2013 and seller sent me a printout with the MBP showing active Applecare Protection Plan from 'Your Service and Support Coverage' on Apple website with a serial number. However, when I pulled the actual SN of the MBP from 'About this Mac' (also from the bottom case/original box), it was different from the SN shown on the printout. So, I went to the Apple warranty check website (https://selfsolve.apple.com/agreementWarrantyDynamic.do) and typed the actual SN and got an error message below: "We're sorry, but this is a serial number for a product that has been replaced. Please check your information and re-enter your serial number. If your information is correct, you may need to contact us." I contacted the seller and he stated he bought it from a dealer that sold him this MBP and it was a replacement received from Apple after the original MBP failed and this MBP has the Applecare coverage. And he stated if I call Apple, I'll be able to confirm this. I don't think it makes sense and am not sure if this is true. I tried to call Apple to but they are closed now, but cannot wait until tomorrow morning. Can anyone advise?
