On some keyboards the keys changed with the Numlock. Your post is not sharing make, model numbers so my guess may be as good as it can be with the missing details.

I have some problems with by keyboard. Yesterday I plugged in an external keyboard to my laptop with Vista Basic. I turned off the computer and unplugged the external keyboard, and afterwards the keyboard didn?t function properly. Most of my keys are alright, but some of them, for example K (I think) became a 0 on the screen instead. But the original zero does also correspond to an actual zero on the screen.
So what do I have to do to fix this problem?
