Cordless Keyboard keeps dying
 

The problem I have is that I can be typing something and then all of a sudden what I'm typing isn't being shown on the screen. Underneath my keyboard there is a button, which if I press it will start to show what I'm typing on the screen. This is happening every couple of minutes and of course is driving me up the wall. Can anyone suggest a solution please. Thanks.

That little button is probably the PAIRING Button, sounds like the Keyboard is losing pairing with the receiver.

Try moving the receiver to another USB connector. Did any software come with it??? Reinstall. Or go to the manufactures website and download and install the latest driver for it.

Really sound like a pairing issue. Are the battery fresh?
