text: perhaps your NumLock is on. When the NumLock is on, only the keys that double as numbers will work - for example, J=1, K=2, L=3, etc. You can easily turn off the NumLock by pressing Fn and F3(or whichever key has NumLk on it) at the same time. Try and see if it works, or you can always call Dell services to speak to a Dell specialist.\n\nGood Luck!
