My macbook late 2008 (aluminum unibody) has stopped charging
It has stopped charging with the "T" power cord it came with. It works with the "L" connecter for the 2009 macbook, but charges much slower. I have checked and my power cord isn't fraying or splitting, but I use it for school so the connector is wrapped up alot. Also, it does say that my battery needs to be serviced, but so far i have noticed no other issues. Suggestions? I have heard that there is a wrong and write way to wrap up the cord. If there is, what is it?
MacBook, OS X Mountain Lion (10.8.4)
