I agree with fihart on this one. If it isn't a year old, it should still be covered by the factory warranty. Get in touch with either the manufacturer or the place where you bought it to get the ball rolling on where you'll need to send it in to get it fixed up.
Thanks. will try, but as I am travelling in Oz and bought laptop in Scotland, proving difficult. What I have done is plug in an old keyboard and just sit with it on top of laptop!
