Magsafe adapters with stuck pins
Has your magsafe adapter stopped working properly? One of the connector pins might be stuck. Apple has published[1] a support article on troubleshooting stuck pins. If you remove your adapter and see one or more of the pins stuck down (the two outer pins in this picture are affected), Apple suggests you try unplugging and replugging the adapter to allow the pins to reset themselves. If that doesn't work, you can use your finger or a pencil eraser to nudge the pin back into position. If all else fails? Visit your local Apple service provider.
