Hey. Um, i totally screwed up and accidentally dropped the MacBook power source/charger. And it seems to me that it isn't working anymore, is it really THAT sensitive? The power's stuck to 96%, and its really scaring me because this belongs to my mom's company. Please reply guys. I'm not really tech-savvy so i really, really need your answer. What should I do other than BUY (oh my) a new one? HELP!!
