Keyboards problem

[tali1]

I have a notebook to which via usb added a keyboard - both worked fine.... but now if i remove usb keyboard the notebook KEYBOARD won't work.....and now some of the notebook keys letters have gone all mixed up with numbers- NUM LOCK is not on -which most claim to be prob- tried pressing the key and no lights come on or off
In Device manager i have noticed 3 enrties (2 of which are for the same keyboard- is this problem should i delete one?.I'm a bit wary about doing anything as the keyboards have acted strange and any solution is not a simple tick of a setting.
I don't know if the 2 probs are related
Ideally i would like to remove the usb keyboard and use the original - but computer only wants to recognise USB

Yeah just delete all the keyboard entries in device manager, restart and it will detect and reload the correct drivers.
