So, the Macbook won't boot up. Well, it did once but when shut down again to reset the various functions that could fix the problem, it just won't boot up again. It's only about 6 weeks old. That's not really the question though. The concern I have is that about a week after I got the machine, I spilled a little bit of coffee on the left hand side of the keyboard. Minor spill, which I wiped clean and did't think much about it. Aside from a couple of keys sticking for a few days, there were no issues for at least a month or more. I contacted Apple Support. I was honest with them when describing the problem and told them about the minor spill, trying to understand if that could be the problem. It's was pretty funny. I was asked if it was "within the real of possibility" that the spill caused the issue. I suppose it's possible, but not likely. Anyway... We couldn't fix the issue, so I have an appointment at the Genius bar. Does anyone have any experience with Apple's method for determining if the problem is related to liquid spill? Is there a criteria they use? If they determine the issue is caused by the spill, do they charge diagnostic fee? Any chance they would cover the repair anyway? At which point it doesn't make sense to pay for the repair and are there any other ideas or options I should consider at this point?
