Have you tried the non-working keyboard on your original CC3 ? and the  
keyboard from that machine on the new machine ? If the problem moves  
then it's a problem with the keyboard, if it stays then a problem with  
the computer :)

If the problem is with the computer, it may be worth checking the  
connectors, and tracks on the board for breaks, possibly re-flowing  
the solder round the keyboard connector.

Another possibility is that the PIA connected to the keyboard is  
faulty, if it's socketed and you have a spare, it may be worth  
swapping it.
