Hey, I can't get my Mac Book Pro to boot. It was working fine and I closed it while on the phone, but after returning to it 30 min later it wasn't responding so I attempted to hard boot it. When I tried to turn it on again it wouldn't start. The screen remained black and the apple start up sound was non existent, but there was power as I heard the disc drive make a sound, the HDD spinning and the light on the front glowed dimly. The battery is fully charged and I have tried booting while plugged in to the power adapter as well as just off the battery. I also tried holding down the control key, command key and power key to restart it after I turned it on. Additionally I reset the PRAM and the SMC. I did notice, however, that either after making an attempt to restart using ctrl, cmnd, pwr or after I reset the PRAM it made the the apple start up sound, but nothing further, the grey screen did not appear, it just remained black. I guess I should add that my MBP has 2gigs of RAM, 2.4g Core 2 Duo, and a 180gig HDD. I don't have any additional hardware connected to it, and all components are stock including the RAM. If anyone has any advice, suggestions, experience with this issue, or a solution to my problem it would be greatly appreciated.
