I have had my MacBook (aluminum) for 6 days, and all of a sudden i go to plug it in to charge (10% left) and the led on the magsafe doesn't come on and the computer doesn't recorgnize the charger (even in system profiler). upon closer inspection i noticed the LED is on on the magsafe, it is just a very faint shade of green. I have tried a charger from a different MacBook but no luck. And i have also tried my charger and a different macbook and it charged it just fine.. so it's probably not my charger. Any ideas?? i know i can go get it replaced.. but i would really like to not have to take a 45 minute drive to the apple store if i can avoid it.. (unless this problem is serious and should be replaced) also, if i get a replacement is it possible for them to just swap my HDD with the new one?
