Yesterday, all of a sudden, my macbook pro (15 inch early-2016) started to forget how to charge its battery.

According to the battery icon, almost everything looks great but one thing. It doesn't charge the battery. (I made some pictures so you can get a visual about the issue)
Whats really interesting about this, is that my charger does work with other macbook pros. Some of my colleagues have the very same macbook as I do and the magsafe goes on, starts with green, then changes to amber; the battery status says says charging.
Another interesting habit is, that when the battery charge drops below a certain percentage, it starts to charge itself, but only with other dhargers. Yesterday I discharged the battery until the laptop didn't boot anymore but said there's no charge. I connected the charger of my MBA, nothing happened. I plugged it into my MBA the indicator light started with green, then I plugged it back into the MBP and it started charging. Im sitting now on a charge of 85% but after I disconnected at that point it didn't charge anymore.

The following pictures describe everything I could put into words.

MagSafe plugged in, not charging

Magsafe plugged in, but no lights visible

What I tried so far:

  • I did an SMC/PRAM reset
  • battery discharge
  • plugging the power cord into another MB and then back

Happened to my brother with a brand new original Apple charger. What he did was to remove the charging extension (thicker cable) and plugged the square power box directly into the sliding plug, and it worked. See below:

This worked for him, but might not work for you, let us know! :)

  • It turned out, that something with the SMC (or what) wasn't working well. Apple support told me they would fix this within the next 2 weeks. So its not that bad

Dont have the rep to comment, trying to answer anyhow.

You need to make sure you have the correct wattage on your magsafe adapter. A 15 inch computer requires a 85w magsafe adapter. If you use a 60w adapter it will run the computer but not charge it. It will however run and charge a MacBook Air that only requires a 60w or 45w adapter.

I guess you already tried disconnecting the magsafe adapter from the 110/220v side as well, as resetting the magsafe adapter might be needed, after all, its intelligent. If not, remove 110/220v and computer connection for 10 minutes.

Otherwise i would recommend replacing the Magsafe adapter.

  • thanks for your answer. i tried with both 45 and 85w adapters, the 45w worked at some point, the 85w didn't absolutely. maybe it just died somehow?
