I was sitting refinishing the living room table tonight and suddenly my Macbook Pro (2.33 17" x1600), which I had left charging on the couch, began making loud clicking noises. I then jumped up, opened it and was greeted by a frozen screensaver, so I did a forced restart. However, my machine just hangs now and will not boot. All I get is a solid sleep light, a black screen, and a little bit of disk noise (No startup chime, no lit keyboard, no usb, etc.). I'm not really sure what could have happened.
