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

I have noticed today that my MacBook Air won't charge. I changed the socket I was using to a different one in the house.
The charger itself is not hot. Has not been used at all today.
Have followed a link on here and tried an SMC reset to no avail.
This is what my system report has to say: (my charger is attached right now - no light)

11" MacBook Air won't start even after SMC reset attempt

I press the power button on my Air and the Apple sound chimes, a dimmed grey-black screen appears and nothing else. I have combed through the communities and the suggestion was to do a SMC reset. I followed the instructions exactly and nothing changed. I initially plugged into my Thunderbolt monitor and ultimately plugged into power with the standard MagSafe cord. Neither changed the outcome. I have had this Air since November 2014.
One of my questions about the SMC reset was how could the device recognize actions while the computer is powered off?
Please help me!
11" MacBook Air, OS X Yosemite (10.10.2)
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
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.

You have to take the computer to the Apple store to have it checked out.

One of the keys you press when resetting SMC is the power button.

Macbook Air won't turn on after SMC reset

Hello,
The fan on my macbook air had suddenly started becoming very loud intermittently even with no apps running. I tried restarting the computer several times, but the problem persisted for about a week. Looking online, I found an SMC reset might solve the problem. However, after doing the reset, my Macbook now will not turn on at all. There is no startup chime or lights when pressing the startup button. The only thing that happens when I press the power button is that the light on the adapter turns from orange to green for second before turning back to orange.
I have an appointment with the Genius Bar tomorrow, but would like to seen if anyone has any suggestions. Thank You

Try the SMC again:

Then try a Safe Boot;

Any change?
Ciao.

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

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

I have a BTHub4 - My iMac, iPhone, and children's iPads all connect to the internet no problem. I cannot get my 2 MacBook Pros or my partners MacBook Air to connect. Have tried diagnostics - says to change DNS but it is correct.

I have a BTHub4 - My iMac, iPhone, and children's iPads all connect to the internet no problem. I cannot get my 2 MacBook Pros or my partners MacBook Air to connect. Have tried diagnostics - says to change DNS but it is correct. I have re-set both router and all laptops - no joy. They can all see the network but cannot connect.

This is extraordinary. I have moved the router and also tried resetting it to its factory strings. We have had this router for over a year and all our devices have always worked. Now all four laptops will not connect to the internet. Only one oMac and our phones and iPad.
I have had far more devices running at once before but now all laptops are timing out on connection. Some say this iIP address is already being used but if I manually set to a slightly different IP address it does not help, noir if I manually set to the correct IP address. Why would all our laptops (four) suddenly be unable to connect?

Help with BBOD! Can't seem to get to the bottom of it. Have tried SMC reset, PRAM reset, reinstall of Mavericks, Carbon copy clone, checked my CPU, Memory is 500GB and I'm only using 250GB thereabouts.

Here's what I've tried;
SMC reset
Pram reset
Looked at activity monitor - mostly seems OK aside from a kernel task taking up memory (approx 460MB) but CPU is around 96% idle.
Fan seems to be running constantly - heats up noticeably when I close the MBP
Despite a re-install of Mavericks, MBP is running frustratingly slow. Just typing is enough to bring on the beach ball.
Have backed up everything, reinstalled from a clone, checked through Apple Hardware test and carried out a Verify Disk Permission - nothing was reported, erased the drive and set up again - problem still stands.
Memory is running at 3.43 GB without anything really running bar Safari.
A little loath to install SMC fan control without knowing what's wrong.
Checked software updates.
Can anyone tell me what the matter is? Does this have a fix?
Have been reading up various posts but to no avail so have resorted to posting myself.
Does this sound familiar to anyone?
Many, many thanks
Roque

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with "Model Identifier." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

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 & 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 :-(

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 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.

shldr2thewheel wrote:
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.

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:

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 or start.

Adapter doesn't show a light at all. Nearest service center and/or Apple store is 45 minutes away. The computer fell about 2 feet last night, but was working fine until the battery died. Trying to determine if it just needs a new adapter, or if I need to make a drive.

Have you tried a SMC reset?

Cooling fan on OS X 10.7.5 runs at high all the time. Have tried SMC reset, putting it to sleep

Cooling fan on Mac desktop OS X 10.7.5 will not turn off. have tried resetting SMC, putting to sleep and force quit programs. Started after replacement of hard drive and LCD cable. Please help! Thanks!

Take it back to whom replaced it.
If you did it, you may need to take it in for service. You have to be very careful how you put the pieces back together and neither put on too much cooling gel which would make it an insulator, and not too little.

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