The next step in the troubleshooting process would be to try and replace the magsafe port, if you indeed know its not the physical charger itself. This sits between your logic board and charger. If you are noticing slow charges and have eliminated the possibility of having a bad charger, it's possible your magsafe port is showing signs of its age. If I am not mistaken this is the part you should be looking for.

Hi

I changed " magesafe DC in power board" but no luck!

please help!

what can I do?

Best Regards

I also have had this problem for quite a while. it isn't the magsafe DC-board so I suppose it's a chip that got short-circuit. But I have no clue where or what needs to be replaced..

Take it in to an ASP and have it tested for this issue:
