MacBook Pro 2012 Battery Not Charging
I have this 1-year old MacBook Pro 13" 2012 model. It was working fine till one day, it decided to die, just like that. Now it shows "Battery Not Chaging, Condition: Replace Now". What do i do? It has done only 200 charge cycles. Resetting SMC/PRAM does not do anything, except that the fans run louder.
What do I do now? Is there any fix (SMC Firmware Upgrade) or do I take it to a Service Center ? I want to avoid paying unnecessary money.

Yes. Take it to an Apple store genius bar and have them check the MBP. The evaluation will be free. If a new battery is required (which the 'Replace Now' indicates), then you should have one installed. Though unlikely, there may be another issue that may not require replacement.
Ciao.

MacBook Pro (2007) battery not charging...
MacBook Pro battery not charging... bought a new one, same problem. Any ideas?
The problem seems to happen to more people at the moment, I know 2 guys who have the same problem.
I guess it might be a software bug in Snow Leopard?
... or it's something like a "time-bomb" to make me buy a new one...I really don't think that the battery is the problem. But I asked them for replacement, just to be sure. I think its a software thing!!!!
I had 2 batteries before and just bought this new third one, because the second wouldn't charge anymore.
Check the stats from my new battery:

Macbook Pro 2011 battery not charging error code
My Macbook Pro just turned 1 year old and the battery might be defective or dead ( Warranty just passed by ) it originally cam with Snow Leopard but I WEB upgraded to Lion (which was far from being easy ... had alot of crashes and hanging happening)
I have the now infamous battery not charging problem. The OSX status bar shows the battery icon with a 'X' meaning no battery. I think the MacBook is not charging the battery because OSX doesn't see a battery.
Today I just noticed that (IMPORTANT) with the power adapter connected, pressing the battery power level button displays a 5 blinks code. Otherwise with power adaptor not connected, the battery seems even too weak to light up even a single LED".
Even though I do a proper shutdown, it is to note that the MacBook Pro starts right away when I plug the power adaptor. I starts right away without me even pressing the power button.
Yerterday I really though the MacBook Pro was not going to work anymore, it kept abruptly shuting down again and again. I couldn't do any of the work I was supposed to.
I did PRAM and SMC resets and eventually I was able to startup the MacBook Pro and do some work but the battery still remains unavailable.
I have 2 of the same 85 Watt charger ( the first one being from a previous MacBook Pro 2008 --- which is waiting to get a repair ) and both performs the same: not charging.
Maybe the battery discharged beyond the point it can be seen my the MacBook Pro and OSX. Just like car battery, if it get discharges way too much, you won't even see the nominal voltage on the terminals even without any load.
EDIT: just noticed that even though it looks like no battery OSX reports that power source IS BATTERY (in the OSX status top bar )It's like mpg for a car. It depends upon how you drive, the weather, the terrain. "7 hours" doesn't mean anything. Your mileage will vary. If I am not doing anything I see 13 hours. As soon as I start surfing or watching a video it changes. Stop obsessing.

Macbook Pro Retina battery not charging
Hello, when I loaded up my Macbook pro Retina today (4 months old) I noticed the battery wasn't charging and the power logo says power source: adaptor, I have tried SMC reset but that hasn't fixed the problem, need some advice as to what to do now?
Thanks
BenWhat % is the battery at? If it's at 95% and above, it won't charge. It must get lower to charge. If it was lower than that and it won't charge no matter what, you'll need to contact AppleCare because you can't service that laptop yourself for this issue if it is a bad battery.

can you please tell me whats wrong with my mbp and how do i resolve itFirst check the connections on the power adapter and the MBP. Make certain that they are clean and see if the spring loaded connectors on the power adapter are not stuck.
Try a SMC reset:

If available, try another power adapter.
If no success, bring the MBP and the power adapter to an Apple store genius bar for a free evaluation.

My brand new MacBook Pro retina display not charging the battery any more after 3 weeks...no green or red Led. Any one now about this problem? Thanks
Either the power brick is damaged, or the charging circuit is on the blink, or both. Either way, a trip to the Apple Store or the Apple Authorized Service Provider is in order, as this ain't no bargain basement toy.
In the meantime, can attempt an SMC Reset to see if it helps. -
My Macbook Pro suddenly will not charge. I tried using 2 different cables and it still will not charge. What should I do??
Look at the power adapter connection on the MBP and make certain that it is clean and not discolored.

Retina MacBook Pro Late 2013 not charging?
Bought my MacBook about a year ago, and very happy with it.
However just a couple of days ago, it stopped charging? The light wouldn't come on at all..
So I opened up my spare MagSafe 2 charger and tried that in a different power outlet and it still didn't work
I've done some research and I have checked that the battery is still in 'good' condition (checked it in the utilities or something) and that it does not need replacing at the moment
so perhaps something is wrong with the port?
stupidly enough I have not backed up my laptop, and it has plenty of important files
what should I do?Hi ridgeleyy,
If you are having an issue with being unable to charge your MacBook Pro's battery using either power adapter, I would suggest that your next step would be to reset the system management controller. Use the steps in this article -

Bonjour, je rencontre le problème expliqué dans ce forum avec mon macbook pro 2012, quelqu'un a-t-il une solutions ?

MacBook Pro 2007 battery not recognized, not charging but working
I recently bought a new battery for my MacBook Pro 2007. As said in the title, it seems to work alright, but it's not recognized by the computer (X in the battery icon), and I don't think it's charging.
I tried to reset the SMC, no change. Unfortunately, I don't have any other computer to test my battery and my powercord on, to see if it's coming from either one of them. And I don't have an Apple Store around.
Do you have any suggestions ?MacBook, MacBook Pro, MacBook Air: Battery not recognized after being fully drained

2012 Macbook Pro Retina battery loses charge quickly.
Any guesses or fixes? I do not abuse it in any way. Randomly in the last three days the battery has had about half the power it normally does. All I'm currently running on it are Firefox and iTunes, everything else is and has been closed since I noticed the problem.
Hello JLaT,
I definitely understand your concern with your battery on your MacBook Pro. I found a couple of resources that I think might help with this.
The first thing I recommend is resetting the System Management Controller (SMC) when the battery does not appear to be charging properly.:
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 can find the full article here:
Intel-based Macs: Resetting the System Management Controller (SMC)

I also recommend reviewing the following resources for more information about prolonging your battery life:

About a year back i had replaced the MLB of my early 2011 macbook pro and it was all working fine. A month back my battery went dead saying "Battery Not Detected". I went to Ample technologies, Bangalore, India and gave it for diagnosis. Ample technologies are the authorized Apple support service in Bangalore, India. After 3 days and no phone calls they email me that "They feel that the MLB MIGHT be the problem and they want to test it by replacing the MLB and i have to pay for their testing". I had already spent 40k indian rupees ($700) less than a year back to replace an MLB and now they want to replace it again at the cost of 43k ($750) indian rupees. I have no idea what to do now. Spending 80k indian rupees ($1400) in less than a year to replace the MLB twice sounds unfair to me. Can someone help me out here ? Is there a valid warranty period applicable , since i have changed the MLB a year back ?
short of doing a SMC reset, you maybe at their mercy.

Help! MacBook Pro Late 2011 Not Charging
My MacBook Pro Late 2011 is Not Charging. I have tried plugging it into multiple outlets and none have succeeded. He is a screenshot of my System Information>Power: http://grab.by/tkOM. I have no clue what happened. Last night we had a massive storm, but I don't believe there was any thunder or lightning. Whenever I plug the adapter into an outlet, the battery usage in the top right hand corner shows the "plugged in" icon, then it shows the "charging" icon. Then it just goes blank and back to normal. I have tried to restart it and do the SMC or whatever, but nothing seems to work. I have had this charger for a little bit over 1 year. Thanks in advance!
- Sellers C.Hey Angelo_here,
I'd run through these steps:
If your computer won't turn on, try each of these steps:
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.

If you are still unable to start up your computer after trying each of these steps, visit an Apple Store or Apple Authorized Service Provider (AASP) for further diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).Note: Diagnostic fees may apply for issues not covered under warranty or the AppleCare Protection Plan (APP).

New Macbook Pro 2012 Battery health.
Hi all, hope you can give me some advice.
I purchased a New Macbook Pro 13" (2012 model) 3 weeks ago. It has now had 11 charge cycles and the battery health has dropped to 86%. I have gone through the calibration process, reset smc/pram but sitll seems to be dropping.
Is this normal, should i return it to apple and have the machine swapped, should i just leave it and if it gets worse get it repaired under apple care.
Intrestingly, Battery health states the battery is 9.3 months old, from the serial number of the mac I understand that that mac was made in 3rd week of october, I just wonder if that battery has been stood arround semi-charged for 9 months and this has damaged it.
Any help would be great, thanks
PaulI would make an appointment at your local Apple Store or an AASP and have them test the battery. My battery 'life' is right on the manufacturing week of my computer. Something's up with the battery - since you're still under warranty have it checked out now.
Good luck,

And a other strange thing is this is wen disable all devices an can run my system lover then 20W in Bettery Mode, Say me powertop this
The battery reports a discharge rate of 20W
2 System baseline power is estimated at 4.8W
why this happen?When your Macbook is fully charged and plugged in, the charger stops charging and your macbook battery will go down to 95% before the charger kicks in again. This is normal.
Enjoy and have fun with your new Macbook.
