I hope I'm in the right place to ask this question. I just installed a new Logitech M310 wireless mouse to my desktop now my keyboard doesn't work but the mouse is working fine. I have a Microsoft 2000 series wireless keyboard and the old mouse was also Microsoft they were bought togrther. I've tried different USB ports, I tried rebooting machine and still the keyboard doesn't work. I hope someone can help me with this problem. Thanks in advance.
Sorry to hear about the problems you are experiencing with the keyboard following the fitting of your new wireless mouse.
It seems that this is not an uncommon problem and unless you are very lucky involves quite a lot of research in order to come to a satisfactory conclusion….
To get you underway so at least the computer is workable try fitting a wired USB or PS2 keyboard.
