Magsafe Charger not charging - when it lights up may not work

Question

I started experiencing this a few weeks ago. Since then I have gone through 2 adapters.
The magnet works and everything, but it doesnt light up, and where that battery is up there it doesn't show any signs of recognition.
I have to wiggle it a little bit and apply some pressure to get it working.
Even then, it still sometimes doesn't work. It'll be green and say "Not Charging".
It doesn't always do that though. Sometimes it will charge. I have a new battery (from around christmas time) so it cant be the battery... i wouldn't think anyways.
Another thing, is when I get it charging, I have to lay it perfectly still. One little tiny bump or something will cause the light to go off and stop charging. I've cleaned the magsafe part and the part it lpugs into the computer. I have the same problem.

Answer 1

I had the same pin problem as many here. My neutral pin (outer most) stop pushing out, I can turn the plug upside down and the pin falls into place. Take a bit of wiggling to get it to charge the computer. This is a new magsafe, only 4 weeks old. I had to have my other one replaced because the exact same pin did the exact same thing again.
