My Macbook air won't charge event though the light on the power adapter is red.

My Macbook is plugged in, and the light on the power adapter comes on. However, I have to jiggle it for it to say it's charging, and then it quits charging after a few seconds. Right now when I get it to charge, the percent on the battery increases like normal, but yesterday it said it was at 0% while charging or the percentage was decreasing. My power adapter is only a few months old, so I don't think that could be the problem.

1 You may need a new charger. Connections should be firm.
2. Reset SMC.     http://support.apple.com/kb/HT3964

My MacBook Air won't charge, what can I do?

My MacBook Air won't charge up at home. Today I brought it to the Apple Store,and it worked OK there. What could be the cause? In the Apple Store, we even used my charger, and it worked. At home now, the green or orange light doesn't come on and the computer loses the little charge it has (4% right now). Very frustrating.

Hi Lisa,
My macbook air has the same issue.
I get no light on the power adaptor (45W) and no charge appearing on the onscreen icon.
This issue seems to happen intermittently and after being fine for the last few months it started again today.
After trawling through a lot of forums I tried a piece of advice which did work and my macbook is now charging.
The advice was to simply heat up the charger a few degrees, which I did by putting a warm fan blower on it. My charger started working within a few minutes.
Hope this may help,
Craig

My MacBook Air won't charge, have tried SMC reset too..

My MacBook Air won't charge using the power cord and it's not the power cord that's malfunctioning. The battery is now exhausted.

My MacBook Air won't charge using the power cord and it's not the power cord that's malfunctioning. I went to Radio Shack and tried two new cords. The battery is now dead. Any thoughts?

Unfortunately, my battery has died as a result of not being able to charge with the power cord. Not sure what an SMC reset is but I have made an appointment to bring my laptop in to the Apple Store. Thank you for your response. Very much appreciated.
Warm Regards,
Carla

I can't turn on my MacBook Air despite trying to hold down the power button and using the SMC method. BTW my battery charger lights up to a green when plugged into the laptop.

Hello cass528,
I would be concerned too if my MacBook Air would not power on. I recommend following the steps in this article when experiencing an issue like this:

Thank you for using Apple Support Communities.

My brand new MacBook Air won't turn on all the way.

Hi my brand new MacBook Air won't turn on all the way. If I try to restart it or shut it down, it will go like it is starting up, but goes to a gray screen and stays there. I can see the mouse and move it, but it won't turn all the way on. What is wrong with it? It had been working fine since I got it, but today it hasn't been.

You may have to see if troubleshooting this issue can help, though the instructions on a process of elimination by symptoms are tedious in the following support article, and are suggested to be performed ahead of trying the process described in the title.
•Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/HT3964
For the actual SMC reset, note subsection in above, instructions click-open on blue text:
>Resetting the SMC on portables with a battery you should not remove on your own
If the computer does not shut down, and just hangs there, try pressing the power button down for 15 seconds. Check the suggestions in the above article to see if any of them can be used, if the computer will power-up.
There is another item that sometimes can help, but the main issue you say could be resolved by the SMC reset; this other thing is involved NVRAM (non-volatile random access memory) so here's an article about it.
•About NVRAM and PRAM:
http://support.apple.com/kb/HT1379
>Resetting NVRAM/PRAM opens in above, click-to-see instructions on how to reset.
You may have to call ahead to the nearest Apple Store for an appointment to see a Genius; or at authorized reseller, their service product specialist who should be trained to understand how to proceed, just in case there is a hardware issue behind the symptoms. When you call, be sure to have the serial number and purchase date available, when you call an official store.
Or use the 'Apple - Support - Contact Apple Support' to start the process...

Hopefully this helps somewhat.
Good luck & happy computing!

My macbook air won't charge

when I plug the charger in it shows the power source as the power adapter .. I've tried switching the sockets and also waiting and doing it again but to no avail.. i haven't bought the macbook from India and i don't know what's wrong .. this has happened a few times

Open System Information>Power and post this from your MBA:
(Make certain that the power adapter is connected.)
Ciao.

I could not power on my MacBook Air tonight until I held down the power button and accidentally hit the F12 key. It is 2 1/2 weeks old and I downloaded Mountain Lion 2 days ago. Help!

I could not start up my MacBook Air tonight, even after making sure the battery was fully charged. I have had it for 2 1/2 weeks and downloaded Mountain Lion 2 days ago. This has never happened before. It started when I held down the power button and accidentally hit the F12 Key. Is this a problem and what should I do about it?

call AppleCare.

Macbook Air won't charge or power on

My MacBook Air is 18 months old and won't charge or power on. Technicians diagnosed logic board needs replacing at a massive cost. Has anyone had similar issues or taken this up with Apple. They refuse to assist as warranty expired.

You are going to have to take the machine apart, and see what damage was done to the board that the MagSafe receptacle is attached to. Might be a single, broken connection. Might be much worse.

MacBook Air Won't Charge to 100%?

I have consistently plugged in my MBA and it won't charge all the way to 100%, is there a reason for this or do they all do this? It goes from (Charged) to (99%) immediately after I unplug it.

sudo -intellect, read the article you linked the OP to. It specifically states that all MacBook Air's have pre-calibrted batteries and therefore, do not need to be manually calibrated.
You are right! I stand corrected. Thanks for the correction.

Brand New MacBook Air Won't Charge

I just bought a new Macbook Air 1.8 GHz (the more expensive version) and from the second I opened it, it would not charge. The only way I can use the laptop is if it is plugged in. When I look at the computer's info, it says BATTERY INSTALLED: NO CHARGING: NO CYCLE COUNT:0
What happened? Was it supposed to come with the battery installed? Should I send it back?

if the store is close take it back and ask for replacement, otherwise call and ask for replacement
you could call support and get it fixed under warranty...
U.S. iPod and Mac technical support: 1-800-APL-CARE (1-800-275-2273)
...but if it is brand new you have a reasonable expectation to get what you paid for, so going for replacement is the beter option

Macbook air won't charge

I bought a MacBook Air in November 2011 so I haven't even had it a full year. It does fine when it is plugged in but it has just stopped charging. What could be the issue?

99% of times this is due to a System Management Controller (SMC) problem and you can solve it by reseting it.
Here is how:
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
I hope this solves your problem
Cheers!

Macbook air won't charge & no light on charger

I charged 2011 Macbook Air yesterday and it was fine last night and again this morning. Then, when it was running low on battery today I plugged in the wall charger (which is a new one I got in July) and suddenly my screen went black and the charge light wouldn't come on. So, I unplugged the charger and then my screen came back. Plugged in charger again and screen went black again. I restarted my computer and still same problem. I even shut down and rebooted but same problem. Of course I didn't back up my files so I scrambled to transfer some to our portable hard drive but I was on reserve power and the transfer did not complete. So, now I have a dead computer. I even just tried the charger of a friend with a MB Air but her charger didn't work for me either. So, now I have just plugged my charger in with the hope that it will mysteriously start working again -still no light showing.
And ideas? I live in southern Mexico and closest Apple Store is in Mexico City...not very close to me :-(

... Is there any way to connect the Air to an iMac and try to charge it that way...or connect just to access my files so I can transfer them off.
The only way to charge a Mac is through its charging socket. Without power, you will be unable to read its disk contents either.
I wish I had better news for you but the only option left is to contact Apple and send it to them or an authorized service provider for repair.

MacBook Air won't charge and charger keeps the green light

I have tried a few chargers and it's not a charger problem because none of them has worked.
This is a MacBook Air from 2011.
The mac doesn't hold a charge anymore. Also, when the battery is at 0% the computer has turned extremely slow. At very few random times I goes up to 3% but I have to maintained it plugged in all the time otherwise it will go back to 0 and become unusable anymore.
The light is always green, and I have already tried doing an SMC reset.
Any ideas or has anyone encountered the same problem as I?
Thank you in advance

thanks for the help! here is the info you requested. This is with the charger connected:
