Hi, I think Mike is right. I would call PC service, and give them the model number and serial numbers and ask if they have had problems with those switches. Most manufacturers have component parts subbed out to others, and some times they have defective lots. You could take out those switches, and add a jumper accross the terminals, then plug it in if they run take off the jumper and replace the switch.
Or you could test the switches with an ohmeter with the tools unplugged.
