Hello, My MBP has been serviced 3 times now, 2 for DVD drive replacement and 1 for keyboard backlight. Last issue was very recent, got it back on this Sunday and now today, it has a burning smell. I purchased it back in August and now I'm worried that I may have problems in the future. It is still under warranty but in 3 weeks I'll be leaving for my home country and they don't have a strong apple service there. I'd have to ship it to US, customs issues...ugh. Electronic devices do break down, but 4 issues in 8~ months sounds like it'll cause problems in the future. Should I ask for a replacement? If I do, think they'd honor? Of course it could be caused by a simple issue but, burning smell, I don't know. This is my 4th MBP and first time going through this many issues. Oh and one more question, I still have my old MBP and I'm planning to format this completely and move all the data to that one. Can I just do that with my time machine HD?
