I bought a new Macbook Air a week ago, after two days the Macbook stoped working and would not turn on at all after I tried to restart it. I took it to a certified Apple service provider and they told me that they might need to open it and replace the hard drive. I honestly didn't feel happy about that. Would apple replace it for me if I take to an Apple store? Or can I just return it and get my money back? Thank you.
