Power adapter connection issues Lately, my Magsafe power adapter has not been connecting properly:


The wires are not worn out as I take good care of them
The issue happens when I try to connect my power adapter to my computer
The LED does not come on and the MacBook does not get charged. I have to unplug and plug the power adapter several times until I can get a connection.
The cord and computer intake seem clean and no pins are pushed down


What can I do?
Even if there isn't any obvious cable damage or bulging, the adapter could be failing. If the adapter is not one of the newer L-Shape Magsafe plugs, the need for a SMC firmware update is moot, but it's helpful to have the system up to date regardless.

Have you confirmed if a second, known-good adapter works on your Mac?

Updated: An SMC reset can also correct magsafe LED issues. http://support.apple.com/kb/HT3964
