Chosen Solution

Hi. I have cleaned everything after someone spilled coca-cola on my macbook air 13" mid 2013. After cleaning all components works, even did a full reinstall of yosemite. But the charging time is extremely long. From 2% to 100% it took over 20 hours. According to batteryhealth it is charging with 2.3 watts. Yes I have tried other chargers with the same result. I changed the I/O board cable and suddently it charged with full power. But the next day when inserting the charger it is charging slow again with 2.3 watts. So… are there any fuses I can change? Or is it the battery that needs to be changed? Battery age 1.7 years, cycles 93, original max 7150mAh, health 95%. But the health got to 99% when the charger was charging full. Now it is back to 95% when charging with 2.3 watts. Taking it to a repair shop wont do any good…because one of the LSI indicators on the logic board is red. Yes I have reset SMC. Update I have bought a new battery and a new I/O board. But it is still charging with 2.3 watts. Anyone know if it is a charge circuit on the logic board? The new battery showing 106% health, Current max: 7608 mAh, original max 7150 mAh. Update

Update (06/19/2016) Now it is only charging with 0.8 watts :/

Mike and Igor, There is probably damage to the charging circuit. Sometimes it is one single component, some other times it is a whole bunch of them. It can be repaired by someone with the right tools, experience, and access to spare parts. However, if the problem resulted from liquid damage and that liquid damage is not addressed properly, there is a high risk of further deterioration of the components and traces on the board. For one, cleaning must be done using a professional ultrasonic and proper cleaning agents. Once done and the board is clean, the charging circuit can be assessed for damage and repaired. If you feel like addressing it yourselves, you have to find the board number, the schematics, and follow the circuit using a multimeter. If you find the culprits, you can proceed to replace them using used parts from donor boards (sometimes necessary, in order for them to be programmed) or new spare parts when possible. If you like to have it repaired for you, check my profile for a link to the nearest qualified board technician that can handle this kind of repair. Many of them on that page repair Mac board, accept mail-in repairs, and offer a valid warranty.

@Mike & @Igor Ivanovski Can you both download this app: CoconutBattery take a screenshot of the console with the system under charge and again running off battery. Post them in an answer so we can see them. Also see if resetting the SMC helps. Follow this Apple T/N: Reset the System Management Controller (SMC) on your Mac Hopefully we can get to the bottom of your problem.

@dan @ Mike at the moment the macbook pro is given to official Apple service for diagnostic . We all know that apple wont make any service on the logic board if the diagnostic find something wrong. As i have seen, small chip for controlling the power for the battery has been probably burned from the water… and if i am right, apple service will only accept to put new logic board which i don’t even want to ask for a price. After i get the results from the “doctor” i will decide if i am going to order that chip and replace on my own , or i will get over it and charge my macbook forever. If anyone has advice for me and Mike, you are more welcome! I will keep updating you p.s. I did SMC, hardware check (nothing shows wrong), i change the charger….. still charging with 2.8 - 3.3w (which takes more then 20h to charge 100%) here is the pic Update (02/29/2016) Snap screen from C Battery

I have the same issue, exept i didnt spill anything on my computer, anyone found a solution to this?

Try This: To address these issues, apply the MacBook SMC Firmware Update 1.4 or the MacBook Pro SMC Firmware Update 1.4 to the affected computer.

Hi All, I noticed the post is a year old but this might help others. I had issues which lead to the final issue of slow charging. Long story short, changed my keyboard with a poor quality one. Some key were not working so I decided to pull the battery connector while under load (while powered on). This shorted my battery showing X on the battery icon. Changed the keyboard with a quality one. I purchased a new battery but was for another Mac model, was still was not working with out Magsafe charger. Having left that battery in appeared to short my Magsafe charger. I purchased a battery and charger which both was said to be genuine, however charging was very slow. Took over a day to charge and would power down in 2-3 hours. I decided to order a top battery, NewerTech which was the one I had before that I shorted. Still having slow charging issues, so I purchased a charger directly from Apple. When connecting the first charger which was said to be genuine, CoconutBattery states charging with 2.98 Watts but when connecting with the charger from Apple it states charging with 5.86 Watts then goes up to 6.08 Watts. I have only installed the new battery in today and started to use the new charger. I am yet to calibrate the battery with the MacBook Pro today. However already showing signs of charging at a faster rate. Maybe purchase a charger directly from Apple, it will be a good investment and might well solve your problem. However, I will feedback my findings once I have calibrated my MacBook Pro. Good luck Mike and Igor Update (12/23/2017) Please check this post Battery Hardware Error Code

I have the same problem and changing the DC-in board did not improve. I’m stuck at around 5 Watts and as we speak, because the computer is doing hard work it’s even on 0.04 Watts. Not OK at all..
