This morning when I plugged in my MagSafe Power Adapter to my MacBook Pro, I heard a 'pop' sound. It sounded like fuse going or something. Then I noticed that the Green light was not turning on, nor was the Amber light. I then unplugged everything and let it sit there for about 30 seconds and then plugged everything back in. The Green light then turned on and the MBP recognized it as a power source. The question is should I be worried? AppleCare expires for me in December of this year. Thanks.
