How old is your macbook?
When did you last put a new battery in it?
When did you last put a new charger on it?

Its an old one thought, about 2-3 year
I havent change the battery or even the charger

If it doesn't work, then why would it overheat when you put it in the bag?

Have you got a model number or anything on a label on it?

Can you try another charger?

What voltage is your battery at? remove it and test it.
