I have a wireless microsoft keyboard 2000 which suddenly stopped typing. The home and calculator button seems to work and was able to type in my password when I start the computer but not when I'm on the internet or in word. I literally had to hold down each letter as I typed but that takes forever to type a sentence. I then decided to buy a new wireless logitech keyboard - same issue. I am currently using the on screen keyboard. What do I need to do to get keyboard working again?
