This evening my magsafe was flickering red and green and when I went to check the connection it felt really hot to the touch. When I pulled the cable it came out leaving the magnet attached to the macbook. The cable is burnt through so it was lucky I was here. After a quick search on the apple site it appears I am not the only one.
If you’ve had any problems with your MagSafe power adapter, Apple has good news for you: They’ll replace it for free. You just need to bring it in to an Apple-Authorized Service Provider or an Apple store for evaluation. If you’re out of warranty, you’re still in luck-they’ll take it back if it’s defective.
Symptoms
You may notice a separation of the white insulation on the magnetic end of the MagSafe adapter. Under continued use, the cable may discolor and the rubber molding may become deformed.Products Affected

You may be eligible for a replacement adapter free of charge provided there are no signs of abuse. Make a reservation at the Genius Bar before visiting your local Apple Retail Store.
