There was a read box over the battery during their diagnostic test (on the display of my MBA).

While at the Apple Genius Bar getting new firmware and software loaded (no CD Drive and Install CD to do this at home), they ran a 'diagnostic test' via there net software and the battery was not detected. So I went to the Apple Genius Bat (trip 1) for help with loading firmware and software. My next focus was to resolve a "flashing question mark on folder when it powered up". Shortly after seeing that the new battery allowed the MBA to power up without the AC charger, I put it on a charger, but did not pay close attention to the charging (or lack thereof) of the MBA or that there was an "X on battery icon". I was able to see that it was a working computer. Here is what I know so far that may be of value to you.:Ī new battery fixed the problem temporarilyĪ new battery from Amazon for ($70 incl tools) had enough juice to allow me to power up the MBA A1370 without the AC charger. However, after a month of research, purchasing of a battery and two trips to the Apple Genius Bar (they are no geniuses BTW), I think I gambled and LOST!!! But I did my research online and on Apple's support/community website to understand how extensive the issue WOULD be to determined if I should gamble and make this purchase with an inexpensive fix. I bought it knowing that it would "not charge" and would "not power on".

I've spent a month on this little Christmas Vacation Project, to get it to work for my son who is in elementary school and needs of a computer for class activity where the chrome book comes up short. Another descriptions with the same symptom/issue is "X on battery icon". I have an Apple MacBook Air A1370 with the same symptoms.
