I had this problem twice (quite some time ago, I think this was PE 1300).
It was exactly the same stroy - identical machines, identical setups, but 
keyboard probs on one of the machines.

I called Dell Support, they changed the mainboard. Things worked fine 
afterwards ...

I don't really know what exactly the problem was. I wasn't really 
interrested, I was happy enough that it worked ... :)
