Option 4: Check Your Battery Health

Checking your battery condition could be significant to avoid charging problem on Mac notebook

To check your battery health, press and hold Option(Alt) button and click the icon of the battery in the Menu bar. You would find your battery condition in the drop down menu. Your battery will be in one of the four states of battery:

Normal: The battery is functioning well.

Replace Soon: The battery is functioning normally but holds less charge than it did when it is new. You could replace it soon.

Replace Now: The battery is functioning normally but holds significantly less charge than it is new. You’d better replace it now, otherwise it might harm your computer in the future.

Service Battery: The battery is not functioning normally and need to be replaced immediately to prevent damaging your computer.

Option 5: Make Sure Your MacBook and Charger isn't Overheating

Apple battery has self-protection function that when temperature gradually grows high like 45 ℃ the battery would stop working. You'd better cool it down to make it work again if you want to charge it. An overheated charger also can not work normally as they are very sensitive to heat.

The simplest way to reduce temperature could be turn off the Mac and let them be for some time. Also you can put a working fan near the computer to cool it down. If you are working outside, put them under the shade rather than exposed to direct sunlight.
