Hi last night I used my MacBook. I put it on charge and went to sleep. I decided I would drive home from college today. I unplugged my MacBook but did not turn it off and put it in My backpack (I hardly ever turn it off. Is that bad?) so I flipped it open and pressed my spacebar to bring up the login screen. Nothing happened. I unplugged it and took the battery out and held power button for 10 seconds nothing. When I push the power button it makes that booting noise (sounds like the hd coming on or fans or something) and the light on the button to open the lid lights up for a second then nothing happens. I called the apple and made a appointment but I wanna know if anyone knows what I can do. also I wanna know if I will lose all of my data. That would suck cause I just bought a drive to back up my Mac the other day but didn't have time yet to do it now this happens Any help would be greatly appreciated. Thanks in advanced.
