I recently purchased a MacBook, I bought a new battery and charger. Today i received the charger and battery. I charged the battery I was instructed, had used it for maybe an hour and it complete shut off. Now I have no lights, no noise when i boot up, the macbook just won't turn on. Can someone please help me i'm at a loss, this is the first apple product i've owned other than an iPhone and I don't know what to do.
