I experienced this behavior two days ago (My MacBook Air is late 2011 version (4.2):
- I can still power up my Mac, with or without MacSafe charger connected
- Battery is not charging
- There is no light.
- I tried to reset SMC but it does not help
- Battery condition is normal
- I tried with few different MagSafe charger but still can't charge my MacBook Air
What is the problem and what should I do?
