Why won't my battery charge?

This is a device that I received for free due to the fact that it would not turn on. After further troubleshooting and testing I soon realized that it was water damaged. I've cleaned the board and components, replaced the magsafe board, replaced the LED indicator (it was too far gone), replaced the battery, and I picked up an aftermarket 65 Watt charger because one didn't come with the device.

After these replacements and minor maintenance, the macbook boots and runs normally. However, the battery will not charge and there is a dim green light coming from the magsafe adapter. My battery indicator on the home screen of the macbook displays a lightning bolt over the battery icon as if it were charging, but it states that the battery is not charging and that the power source is the power adapter.

Other Notes:

  • The macbook will not turn on with just the power adapter plugged in and the battery removed. The battery must be connected for the device to even power on.
  • I have tried an SMC reset several times to no avail.
  • I am using a known-good 65W charger from my girlfriend in case the one I received in the mail is faulty


  • Could this be a chip shorted out on the board? If so, there is nothing with visible burn damage. Could someone provide me with a schematic of this particular board with an idea of what chips they think could be the suspect?
  • Could it be that my charger needs to be 85W vs 65W?
  • Could it be a software issue that I'm missing?

Any help is greatly appreciated. Thanks!

Here is a shot of my logic board. I am currently using my macbook so I can not take it out. If what you need to show me is on the other side of the board, then I can take it out and take some more pictures. Thanks guys!

Answer this question I have this problem too

Is this a good question?

Does anyone have any information?


It is actually a 60w charger you need. The 65w might screw with your battery and cause problems.

I made a mistake. It's actually a 60W charger.

@body_caul I'd start by checking the current sensing resistors near U7000 ISL6259 and the traces between them and the U7000 ISL6259. If you post an image of your logicboard we could point those out for you. Use this guide for that. Otherwise you need to scrounge the internet for what I assume is a 820-2879 logicboard schematic. Check yours just to make sure. the 65W charger is okay for your system to use.

Thanks for the reply! I'm going to be out of town for a couple of weeks, but when I return this will be the first thing I'll do.
