I connected my Sony digital camera with the MacBook and the screen turned black. I wonder why because the Sony camera was not on at the time and technically could not be accessed. So I thought it might be temporary and I turned on my camera.

Well, it did not work, but my MacBook Pro has been dead since then. It will not turn on - when I hold the power button for five seconds, nothing happens. When I connect the charger cable, the green light is very dim and blinks a little (with about 20% illumination).

I wonder what the problem is. I have to call Apple Care, but just so that I know, what could be wrong? Is my MacBook permanently dead? It might be under warranty but I am not sure.
