Logitech K850 Keyboard Is Not Working But The Mouse Is?

If your Logitech K850 keyboard is not working, resynchronizing it with your computer is often the first step, as wireless keyboards can lose connection or become out of sync, leading to functionality issues. To resync, turn off the keyboard, press the Connect or Reset button on the receiver, and turn the keyboard back on to establish a connection. 

If resyncing doesn’t work, try resetting the keyboard to clear any temporary glitches. Furthermore, deactivate your Windows accessibility features like Filter Keys, which may interfere with normal keyboard functioning, and update the keyboard driver through the Device Manager to resolve compatibility issues. If none of these works, you should consult a professional computer repair technician.
