I'm beginning to think I'm gonna have to give this lap top away for someone to play with! Its great in everyway but the number nine digit. Its stopped working, have no idea whats wrong, all the other keys on the lap top are fine. I did get this from Cash Converters 12 months or so ago, never had a moments problem but now I can't use it, wont work. Whats wrong? Is this something that is easily repaired? Or should I pack it in and get another.
