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?

Best Answer

Your issue is not normal obviously but this could be a sign that something is wrong with the hardware.

The best advice is to go to an Apple store or an Apple Authorized Service Provider and let them look at it.

The issue could be your battery, it could be the MagSafe board or it could be the logic board.

I wish I could help you more but without seeing the unit with my own eyes and taking it apart I can't say for certain what it is. I doubt it is software and therefore encourage you to reach out and find someone who is certified to open Macs.
