Hey I just want to know if anyone could help me diagnose an issue with my macbook pro (mid 2007 - 2.2 C2D, 4GB RAM) running Snow Leopard. I was using it a minute ago, and the screen just went blank on me. After closing and opening the lid a few times hoping to bring up the password dialogue, I opted for a hard shutdown. I got the usual dong on startup, but with no display. I attempted to plug in an external display, but still get nothing. If I shut the lid, the power light does not flash, indicating that it isn't sleeping. I used target mode and verified the hard disk (a long shot, i know) but it was fine. I guess what I'm asking is if anyone knows a way to figure out which part is wrong with it. I can't see what I'm doing, and the lack of sleep worries me that it isn't even booting the OS. I've also tried resetting the SMC and PRAM with no luck. I've had a horrible month. First my Mac Pro's video card, then one of its displays, and now my laptop.. *sigh* Any and all comments are welcome..
