I have no idea what I am going to do with myself. Basically the down button was obviously stuck (even though it didnt feel like it was) and was making everything scroll down, switched it off and back on again and nothing worked, it wouldn't light up and the only thing i can physically do is switch it on and off, not even safe mode works for entering my password. Now im left waiting for a few days for a genius bar appointment and now i'm really fearful that its water damaged and that's what caused it as my hair was wet and perhaps a stray drop somehow ruined my whole keyboard? because I most certainly have never dropped any substantial liquid on it? Any ideas?
