Ummm...hmm...no cursor/mouse movement and no response from keyboard COULD be something else, like a connection problem between these parts and your screen. Could still be a graphics card issue (since the graphics card is responsible for what you see on your screen). Now, I'm not sure of the specs of your laptop, you could have integrated graphics. In that case...that could be responsible for everything. I don't know how much it would cost to repair that. BUT, in these cases, your harddrive should still salvageable, since it's a different compartment, unrelated to these things.
