MacBook Air charging light stays amber and does not go green and machine does not boot or even chime
I had a similar thing happen to my old Macbook. I discharged the battery all the way down and then couldn't recharge it for about two days. When I finally could charge it, it wouldn't charge or turn on. It turned out to be the battery. You can probably get a replacement battery from Apple (if it turns out to be the battery), but I found cheaper options on Amazon.
