Not everyone has tech-savvy friends, hence the reason there are places like best buy and circuit city to fix these problems.
I'd call Gateway, Annie or take it into a computer shop and see what they can do about it, especially if you're not comfortable chaning out laptop keyboards or anything on your own. For a temporary fix, plug a regular keyboard into usb port. Sure it's no practical, but it'll work until a more permanent soloution can be found.
