I was using my new macbook air on battery power today and then all of a sudden, my battery dropped from 60% to 13%, then a few minutes later I got this 0%. I figured that couldn't be right, so I closed the lid and reopened. I then got no battery found? The computer was still working fine, but I figured something was wrong. I then Shut the computer down and then it wouldn't turn back on. I then plugged it back in and it booted up. Has anyone else had this issues? I've uploaded screenshots.
