Ok, so yesterday I come home from school and see that my macbok's charger's light is a dim green. I didn't think much of it. I drained that battery down to about 50% before plugging it back in. Upon plugging it in, up in the menu bar where it tells you what your battery life is it says "Not Charging". I found this to be a little strange so I unplugged it from my macbook and plugged it back in. Still nothing. I heard some where that if you lick the end of the charger it would get an electoral current going, or something like that. That still didn't work. I finally looked at the magsafe port on my macbook and noticed that of the gold/bronze things in there was a little black in the middle. My charger on the other hand looked fine. This is the second charger I've had to buy and it's worked fine up to this point. Also the magsafe port on my macbook is kinda dirty. The macbook I have is the aluminum unibody from 2008 I think? Sorry if this story was unnecessary or this question has already been ask.
