My macbook pro early 2011 wont boot my Macbook pro early 2011 wont boot i tried pretty much anything, i changed the hard drive cleared the Pram and SMC and it still wont work. When i turn it on it has the SLR on but Im greeted with a black screen. The fan and SSD turn on.
My first thought is the screen--maybe it's booting but the graphics aren't working or the screen isn't working. I have that periodically with an old ThinkPad running Linux. Try connecting to an external monitor and booting.

Another thought: try booting with an external startup disk.
