Keyboard wont work

Well there are two things you can test before replacing the keyboard entirely. First thing is if you have a usb keyboard try plugging that in and see if problem repeats itself on that keyboard, second thing is try turning off the computer and reseating the keyboard and see if it repeats the problem. If you have to replace the keyboard, might i suggest the warranty first, asus normally has a pretty good warranty, then try a good shopping search to find replacement.
