Hey...I've recently begun having issues with my MagSafe on my MacBook Pro that I got in August. I went to go charge my computer yesterday after watching a movie on the battery with a friend. Rather than get the Amber light, I plugged the computer in and it lit up with a very faint green light. The computer showed that it was operating off of AC power and acted like it, with the screen getting brighter and all. In the battery menu, it read "Calculating....until full" without ever updating. I finally checked the percentage and found my battery was draining! So then I took the battery out to see if the computer would run without the battery in it and just with the MagSafe. Well, interestingly, it does. So, what could be the problem here? Its obviously the MagSafe or the battery, but I have no idea how to find out which one. My OS X install DVDs are elsewhere, so I can't run the hardware diagnostic. I have reset PRAM and the SMC. Your help is appreciated!
