2008 1st gen air not charging
well it has been in a carry case for a while and battery dropped right down to zero.
It now seems only work on mains.
and forgets date/time if turned off.
It was holding charge before storage.
It seems my fiancee signed out rather than turned off when it went to storage.
It has been plugged in for 24hours and charger tip always has green light.
Says 0% not charging on menu bar.
done PRAM and SMC reset.
Has she killed battery?
