I just got this problem with my Magsafe adapter that came with my Macbook (late 2007). The macbook would charge, but then, the LED light on the adapter would go from bright orange to a dim green. Then, (I think..)the macbook would just stop charging until I unplug it and plug it back in. I searched it up on the web, and found a lot of these problems! Does anyone know how to fix this? What should I do? The Adapter isn't burnt or anything, though. I have had 302 Recharge Cycles, and I have had my macbook for 7 months, and I still can reach at least over 3 hours at 83 percent with screen brightness at medium, wireless on, and bluetooth on, and 5 applications running, so would you think it was the power adapter's problem? Or the macbook? the battery? Please!
