Okay so i had a school project to do and stayed up doing it late on my macbook pro... i had to wake up like 2 hours later so i decided just to let my macbook pro sleep instead of shutting it down... fast forward to about 2 hours later and tried to revive my macbook pro from its sleep state but all i see is a black screen. I tried to restart it, took the battery out, etc but no dice. Its weird because when the macbook is open (when you can see the screen itself) i don't know how to explain it but the white light on the macbook pro is very dim.. but when i close the macbook pro the light is bright white... i'm not sure whats happening. Additional details : I don't hear the chime or anything.. i know the cpu is working because i hear a noise.... what should i do? Thanks.
