Ok, I'm quite new to technology, laptops and forum discussions. I've been living in outback Australia , climbing and being a freespirited bum for the last two years, so bare with me if my question sounds paranoid. What happened, previously, I bought an Apple MacBook Pro (the very first edition) but 5-8 months later it had a kernal panic and the screen when black. All attempts by myself and more computer savvy (apple care) people couldn't fix my problem. SIX weeks later, they resolved my problem by sending me out a new laptop. My original laptop was a 15" 1.8 GHz blah blah. So the model they gave me was a 15" 2.GHz blah blah. It was a bit of an upgrade. I was just happy to get my hands on my assignments/ uni work and files again. Anyway, my question is, after about one or two weeks playing with my laptop, I look at it carefully and realise the casing at the top right hand corner exactly where the 'eject' button is has a slight bend in the surface. I run my finger over it and the surface is definitely not smooth. So I look around again. I see very faint marks which are located about where my old laptop had marks (caused by bumps). I begin to wonder if Apple Care really did give me a new laptop. Anyway, I think to myself, well, each computer must have a unique serial number and checked the serial number on the computer with the box that it originally came in and the old box that I still had at home. Yeap the serial number mached up with the right box. Still, I'm paranoid, so can anyone out there, is there anyway, AppleCare could have scammed me and repaired my old computer and given me the impression that I have a new computer? Thanks in advance for taking the time to read through this post and answering!
