3 options to try: 1) Check that correct language keyboard still loaded; 2) Make sure its QWERTY and not DVORAK keyboard setting; 3) Switch off, remove Logitech, plug in an old keyboard and see if problem still there. With old keyboard and no Logitech, delete drivers for Logitech keyboard, switch computer off then back on slowly, reconnect Logitech and see if problem solved.

If the problem persist, swap computer and try, if it does not solve then contact customer service for replacement

Try that keyboard on another laptop or desktop computer. If it reacts the same way then you know for sure the keyboard is bad. If it works on another computer then that means its an issue with the original computer.
Also check to make sure you have fresh batteries inside of the keyboard as well.

Make sure all connections are free of debri....USB connections can become wallerd out so to speak and create the intermittant problem... Built in keyboard could have been loosened underneath the keyboard on notebook is a flexible connection that if pc has been droped or fallen so to speak could be needing to be reseated........
