"Water Damage - home button no longer works"に関する回答This is what I'm going through right now. The home button works but it's progressively getting worse and now I have to press down hard on it to get it to work. I was wondering, if I take it in to Apple, would they be able to diagnose the issue without me having to pay for it?
"MacBook only boots fully occasionally, otherwise black screen"に関する回答It's probably your logic board. Same thing happened to me a few months ago before taking it in to Apple.
