Magsafe adapter not charging unless I manually touch pins

So I came across a very weird issue. I havent used my mac in a little while until today. I went to plug in the charger and it wouldn't charge. There is not light on the connector and the mac was not showing it is connected. Tried resetting SMC but didn't work.

Now, the strange part... I was trying to clean some dust inside the connector port on the mac itself. With my stupidity, I was using the end of a pair of scissors to clean it (metal). I accidentally touched the outer and second outer pins together (ground and V+) and there was a small spark. I figured I probably fried it but I plugged the charger in and viola, the light came on and was charging my battery.

I went to unplug the charger and try it and plug it back in and it wouldn't charge again. I figured I would try to touch the two pins again just to see if it was a coincidence. I touched the pins, a small spark emitted (because of the short), and it worked again. Now two questions. Why does touching those pins make it work and what can I do to permanently fix it? Thanks in advance!

It sounds like the contacts on your macbook and charger could use a good cleaning. I would recommend removing the battery from the macbook, holding the power button for 30 seconds and the using a little electrical contact cleaner to clean the contacts on the make book, ( you could spray a little on a cotton swap and rub ). Unplug your charger from the wall firs then unplug it from the computer to ensure the power drains from it and do the same for it.

Chances are you are just cleaning enough to make a connection but the charger is making it dirty again when connected. If for some reason the cleaning doesn't work then it might be time for a new charger.

I bet if an aftermarket charger is used. The macbook will charge.


What would make the aftermarket charger special? Just curious


Thanks Shelton! Works well for now!
