You'll prob have to send it to the manufacturers.

I was sick on my laptop once upon a time, and the "a" key stopped working after a few days, I took it to PC World (I had insurance with PC World) they said to just send it to Sony under warranty. Sony picked it up by courier and returned it a week later fixed, after I had a bit of debate with them when I refused to install Windows because I said they didn't need to boot the computer up so linux was fine..
