repaired
Hello.
My mac book had returned from repairing.
Its battery was changed.
Before repairing, the battery was swollen. And I was used to seeing it.
So, repaired device looked like dented instead.
I'm glad that I can close laptop completely.
This time, I got advice that it is not good to always use it stay charging.
After now, I am going to use it more carefully and keep using for as long as possible.
