about a year and a half ago i bought a 15inch powerbook but no applecare or anything,,just standard 1 year warranty,,,,about 7 months after i bought it, my ac adapter stopped working and i couldnt get it plugged in to charge.....so i went to the apple store, they gave me a brand new one since it was under warranty...now, that adapter is doing hte same thing as the first and isnt working once again, but i dont have apple care and the computer is over warranty...is the adapter covered since its only 7months old though?
