Plugging in your charging cable and your MacBook battery still not charging can be frustrating. But have no fear, not matter if it's a MacBook Air battery not charging or a MacBook Pro battery not charging, there may be a fix.
Here are a few troubleshooting tips you can try to get your battery back on track.
Just like software apps on your MacBook can get frozen or bugged up, so can the hardware that controls the charging of your MacBook. A simple reboot could reset the hardware controlling MacBook charge and could fix the problem of your battery not charging.
If your MacBook Pro battery isn't charging, the most likely place to check for trouble is in the MagSafe charging cable. It could be frayed, broken, or burned. A simple way to see if it's the problem is by doing a thorough inspection of the entire cable.
Another possible problem could be your MacBook's power port, where the MagSafe cable gets plugged in. It's quite uncommon as Apple went to big lengths to ensure the MagSafe port is protected against accidental yanks and trips over the cable. If it's indeed the problem, could mean a replacement of your laptop - so check to see if it's still under warranty!
Look for any discolorations, burns, or dents inside of the port. If any of these symptoms appear, it could mean your port is damaged.
If your port is damaged, take it into a local Apple authorized computer repair store or an Apple store to get it fixed.
SMC, or the System Management Controller, is a chip controller that is responsible for several operations within MacBook computers.

If non of the above tips worked, the problem could be as simple as overheating. If the top or bottom of your laptop is hot to the touch, then this could be the culprit. Just place a fan near your MacBook to cool it down, or simply turn it off and let it be for an hour or two.
Overheating can stop your MacBook Pro or Air battery from charging if the thermal sensors within the computer detect a drastic rise in temperature, and shut off access to the battery as a safety precaution.
If the problem STILL persists, unfortunately you've got to take your MacBook into a repair store for a fix. Every laptop has it's own quirks and problems, and at this point it's better for a professional to take a look into the problem as more than likely it'll have to be a unique fix.
