Let me contribute too!  Some wall sockets are not grounded properly.  So
you might have a three-prong socket on the wall, but it doesn't mean
you've got a grounded three-prong socket on the wall.  Before you
investigate, make sure you trip the breaker for that socket.  Then make
sure the ground on the plug is attached to the bare copper wire from the
power cable.
