So my computer is reluctant to charge. Some times it does sometimes it doesn't. I figured it can be 1 of 3 issues. The charger it self is starting to go bad.(This has happened before) The computer itself doesn't want to charge any more. The contacts between between the magsafe connector and the computer need to be cleaned. This is an original macbook so it is just shy of 5 years old now. 1) I tried using my friends charger. The first couple of connections didn't want to charge the computer. But every other connection after the first few did charge the computer. After that my original charger did charger the computer. However this morning it wont charge at all no matter how many times I disconnect and reconnect it. 2) Based up on the first scenario it may have been a fluke. I guess I need to borrow an other charger to test again to make sure the computer can still charge. 3) Whats the best way to clean the contacts between the magsafe connector and the computer? Any other ideas I can use to confirm what it may be? At this moment I'm leaning to needing a new power charger, but I want to be sure. I guess this might be forcing my hand to get a new computer. I had hoped to wait another month or two. Edit: When I say charging I mean both charging battery and powering the computer. When I plug the charger in the computer doesn't even recognize it.
