I had my Macbook Pro plugged into a wall outlet last night. I had run the battery to about 8% and was just starting to charge it. It was plugged in and then suddenly stopped charging, no green or red light came on on the adapter. I do know that when I started charging it I had the power cord contorted a little just because the outlet was in an awkward spot. Maybe that's what did it. But I've tried charging it in other outlets and it still won't charge, with the battery in and without the battery. I inspected the power cord and have seen no damage or frayed parts to it.

I've noticed when the adapter is plugged into any outlet that it starts making a clicking noise, as if there is a charge going through the plugs into the adapter but it's not working. This clicking noise makes me believe that maybe the adapter is just fried?

Also, I haven't been able to try charging my laptop with another power adapter. If it works, I'll let you know.

Is it possible I just need to buy a new 85 watt magsafe power adapter?

    I literally just had the same problem - clicking and everything. Can anyone help? I can't get a charge at all though.

    Here's an article on troubleshooting MagSafe adaptors:

    Since you were able to charge your Mac with a 60W adaptor, my guess is that your 85W adaptor is dead. The clicking noise makes me think it may have an internal short and you may be hearing a sparking noise. I would unplug it and use it no more.

    If you have access to an Apple Store, you can take in your old adaptor for evaluation. It's possible it sustained damage from normal use, or it's possible that it had a manufacturing defect of some sort. If they feel that it was defective from the factory, you might possibly get a free replacement. No guarantees of course, but there were some faulty original MBP adaptors produced, and you could possibly have one of them.

    Good luck!

    I've also had the exact same problem 2 years ago. I remember I accidentally put my foot on the MagSafe's connector (it was on the ground and I walked there). Like for you, the cable had not visible damage, like the connector. I still don't understand how walking on it made such a problem.
