Wow. You could probably send it to HP, but most likeley that would cost you more than buying a new one online. You could possibly open it up and see what is wrong with the screen, but I don't think you would be able to fix it. As far as the ketyboard, pop oft the enter key and see if there is any visible damage under it. It may just be in wrong. I remember a similar thing happened to my 810-C....screen problems are not good. Just a random guess, something may be wrong with the touchscreen receiver thingy
(that sheet under the screen...don't remember what it is
) or the wire that connects it, on that portion of the wire.
-Good luck...
