Battery suddenly stopped charging, magsafe stays green
I am having a very annoying problem.
The battery of my MBP early 2011 suddenly stopped charging. It was all OK until a few days ago when I realised the battery won't charge. The computer works OK (also I feel it is a bit slower than before) when it is plugged to the charger but the magsafe is immediately turning green and nothing happens after that.. no charge. If I unplug it, the computer stops working.
I tried SMC and PRAM reset, removing and re-installing the battery.... I called my local MacBook repair shop and they said they can probably fix it for $350 (australian). I have tried the charger on a friend's computer and it worked fine... Any idea what is going on? I dont want to pay 350$ if I can get a bit of help in here.
I attached a screenshot of coconut battery just in case that helps.
Thanks for your help.
Is this a good question?
