Windows 7: Microsoft Wireless Keyboard 800 not working.

Microsoft Wireless Keyboard 800 not working.

Hi, I have the Microsoft Wireless Keyboard 800 and Microsoft Wireless Mouse 1000 that both use the same USB receiver. I've had them for over a year with absolutely no problems. However, I unplugged my USB receiver as I have done many times before and then plugged it back in. The mouse carried on working as usual but the keyboard didn't work at all. I tried new USB ports, a different computer and a laptop and nothing works. I have tried new batteries and the little green light in the bottom right comes on but it still doesn't work.

On my Microsoft keyboards when the little green light stays on it indicates weak batteries.
Have you tried rebooting after installing new batteries?
Have you checked Windows Updates. It should look for driver updates for Microsoft hardware.

You say you have unplugged you mouse and keyboard transceiver many times; why would one do that.

Please update your system specs it will help us help you.

System Info - See Your System Specs

Some good information here from Microsoft.

When I type in Word 2010, frequently my keyboard will refuse to type. It will type a couple letters and then I have to wait to get it to go on. Then it will type a few more, etc. Another time it will type without an issue. Very annoying! I have changed the battery. Any suggestions?
