Compaq laptop nx6325 input problem

I have a Compaq nx6325. The keyboard and the control pad do not function anymore. The usb ports do not work either. I have tried to add a external mouse and keyboard. Took the computer to work to use a docking station and it does work via the docking station. The wifi also works fine.

Does the motherboard on the laptop need replaced? or one of its components?

Thanks,

Gerry.

usb and keyboard, well if they both went at the same time then it will need a new motherboard by the sounds of it
