Hi I bought a macbook pro in China, and it has been 3months, and I have a apple care registered. My Macbook had a lot of problems and even got the main board replaced! There are many problems still such as missing serial number, outside (bottom and top - with apple lighted logo) aluminum, power button not popping out completely (does not match the other parts' height. What should I do? Does it cost to change the bottom and top cover of Aluminum MBP? P.S. I bought it in China and I'm planning to have a repair in South Korea. With the Apple Care.
