Macbook is not charging , plugged in, no light
My school provided 2.4GHz macbook is not charging but the charger is plugged in correctly, I get no light no orange no green absoloutely nothing happens. I tried using a different charger but that again would not work so I'm assuming its a problem with the macbook its self. THe thing is, is that this macbook is merely 1 year old (it's less than 7 - 8 months! ) and yet it already failed me, extremely disappointed, apple. My school wants to charge me $210 just to replace the whole components at the bottom or w/e ...they didnt even check to see if it could be a broken battery inside or something so I tried to do that but stopped since I found ot that the bottom part of it was all covered in the white plastic - i think the term is unibody. What is wrong with it? On another note, I checked the power cycle count with what little battery I had and it was around 2500 - 3000 and I barely had it for a year! Why is it like this? It was also a refurbished macbook I believe...any help would be appreciated, what can I do ? thanks!
