Hi, I have a 2011 MBP 13'. I have problem with my mbp as it will not charge when it's on and will only charge when it's off. Once I switch it back on, it will change back to green light and showing that 'battery is not charging'. Even if it charges when the mbp is off, it will take forever to charge. I left it overnight charging and the power only increase like 10-20%.

I had done the following but none of this work.

Replaced a new battery (however, this already happened with my old battery, and therefore i replaced it hoping for the best)
Tried 3 different chargers
Reset PRAM and SMC
Clean my charging port

Anyone experiencing similar problem before?

I've only encountered battery draining very fast and it resolved after replacing the battery.
If the problem persist, I think you should consider it might be mainboard problem....

Send to Louis Rossman.
Quite costly for Malaysian though.
$300 for anything that's wrong on your board.
If anything breaks after his repair, you can send it back and he will repair FOC

Thanks. I've replaced my battery and problem persists. Ended up there is faulty with my logic board. Replaced mine for 2.1k at Machine

2.1K might as well get base model 2011 Macbook Pro haha

nah, didn't think of that as not too sure where can i still get one but it's working well now so didn't really care anymore
