Have you checked for a blown "Pico" type fuse on the motherboard close to
the keyboard connector? It probably looks like a 1/2 W resistor without
the colour bands - but with something like "2A" printed on it. If you don't
spot it right away, you could use an ohmmeter or "beeper" to follow the
traces from the connector - just make sure that it does NOT exceed 5 V. Pull
the plug, and ground yourself to the shiny metal of the power supply box to
avoid static electricity problems.
