MacBook Air (Mid 2011) doesn't charge

I have the same thing happening on my mid-2011 air. Not cool.

Oh man, this is happening to me, and I'm worried that the problem is with the computer and not the charger. my september 2011 MB air recently started to have this problem, and I switched it up and used a seperate power charger I had around the house, and it seemed to work fine for like a day, now it seems neither of the relatively newish chargers will charge my mac on a consistent basis. However, they both seem to charge my older mid 2009 mbp. Please tell me this isn't happening. I don't have an apple store within 100 miles of me. I'm not thrilled at the prospect of sending my macbook away either. Darn. This is the third mb i've bought out of 4 in the last 5 years that has had this same issue eventually. It has never manifested itself so quickly though.

This is happening to me as well, same model (13"), have had it since Christmas. This happened twice before and unplugging the charger reset it and then it charged. This time, it won't charge no matter what I do... Very dissapointing as the battery is dead, no way to make backups, etc. Off to the apple store to resolve this.

I'm having the same problem with a twist. 11" MacBook Air, mid 2011 model. My original adapter stopped working -- no light, no charging. Tried switching outlets...nada. Tested a 60W charger from a MacBook Pro, and everything worked fine. So I went to the Apple store; they tested the charger (but not the computer), agreed it had failed, and gave me a new one. Problem solved...temporarily.

A week later the new charger is working, but the magsafe light isn't. It occasionally lights up after rebooting, but goes dead within a few minutes. Sometimes works after jiggling the connection, sometimes doesn't. Resetting the SMC has no effect. I'm theorizing that there is a loose connection on the computer end. Will make a return trip to the Apple store when I have the time (or when the charger completely fails..), but am curious whether anyone else has had this experience?

I have the same problem. I figured out why it is a sporadic problem; the problem is only seen if you plug in your charger when the battery charge is below the safe zone and into the red (low battery) warning zone. It works every time if above the warning level and almost never works if you plug it in after it has gone down into the warning level. Thus the computer does not recognize the charger beyond that point. I don't know if a new charger or new software will fix the problem.

What u descirbe is not normal. You should change your charger.

If you look closely at the connector (with the light) it has 4 spring loaded contacts in it. Don't touch these while it is plugged in. If you use a small flat ended prod you can carefully test to see if these contacts move freely. If one or more were to be stuck it would prevent the connector from making proper contact with the charging port on the MBA. Careful manipulation of the spring loaded contact may free it up again. Do not use fluids to clean this connector, it could be fatal to it.

For me the solution was:

* Reset the SMC

* Let the Macbook Air discharge completely (till 0%)

* Reconnect the charger

Not sure if the Reset SMC step is needed or not, maybe just letting the battery discharge is enough in some cases

I had this problem once, and somehow I had managed to get a tiny piece of metal wedged in the laptop where the charger connects.. I could barely see it, but the charger could not fully connect, is took a plastic paper clip and flicked the metal out and no more issues..

Your Magsafe connector and/or adapter is about to die. I had the same issue. I took it in to the local Apple store and they swapped it out with a brand new cord, with no questions asked. The MacBook Air was six months out of warranty.

Doesn't hurt to ask!

Have a nice day.
