Keyboard working but caps lock light wont come on or Num lock wont turn off

Hi 

I have recently recieved a new work laptop, the keyboad is working correctly but the caps lock light wont come on or the num lock light wont turn off. I have updated all the drivers and completed a hardware test everything has passed.  

I have also tried using the FN button but it makes no difference. Any help would be great , thanks
