Issues after replacing swollen battery
I recently replaced swollen battery on my 2018 15” MacBook Pro. After replacement there is a problem, sometimes charging adapter is not charging (the charging icon appears for a second and disappears), but this problem is not permanent.
The charging adapter starts working if I plug it to an other MacBook Pro, or after waiting for a while, or if an other charging adapter is plugged in.
Third-party service said that the problem could be caused with a faulty charging adapter and recommended to replace charging adapter.
I didn't replace the charging adapter yet, because I'm a little bit confused.
Please help me, what should i do? I don't know why my MacBook’s battery is swelled.
If you need more details, i can answer to your questions.
