I bought my unibody MBP back in late July from the Apple store here. It's been a great machine. Except all of a sudden my headphone jack won't play sound. I realized this last night as I tried to listen to music on it while surfing the web. I've plugged headphones into it maybe 10 times total. And they worked every time before. If I unplug the headphones and plug them back in repeatedly I can get them to work after about the 4th or 5th time. When they do work, the sound is great. Anyway, I made an appointment with the genius bar this afternoon to show them and see if there is anything they can do. Obviously, after paying $2,500 for a laptop I would expect it to run completely flawlessly. But at the same time, I'm hoping they don't offer to replace it with a refurbished one. In fact, I would prefer to not even get a new one. I love this one, I guess I just hope it's fixable. Any one have any idea of what I can expect to happen? Should I backup my data assuming they will replace it? Should I just expect to have to leave it with them so they can fix it? Will they just say "sorry, tough luck" and send me on my way? I wish I almost wish it was a bigger issue than just the headphone jack. It almost makes it not worth the effort. And before anyone asks: - No it has not been near any water spillage (I imagine they will conclude this when they run the light test in the headphone jack) - It has never been dropped - Yes I have tried 3 different pairs of headphones and gotten the same results.
