Q: Does Mac Book Air has a coin battery like the one you find in the logic board of Desktop computers?
A coin battery normally found in desk top computers. Is there one in Mac Book Air?
My Late 2009 Mac Book Air is not booting.
Is there a coin battery in there, addition to it's recharchable battery?
Regards

you mean a watch battery to keep some rudimentary base ram active, no.
some computers have this, the battery powers a chip called the Real Time Clock (RTC)
it has no bearing on booting however.
