I bought this computer late last year, probably in October or November. Everything was fine until tonight, I was studying and I noticed I was at about 35% so I plugged it in. Soon, I noticed that it wasn't charging. I tried four different outlets in different rooms and two different chargers, so I am quite sure that it is neither a circuit or adapter problem. I tried shutting it off and all that until it finally died, and now it will not turn back on. I made an appointment at my local Genius Bar, but if anyone has a more immediate solution, it would be appreciated as my exam is in the morning. Thank you!
