Hi Peter;
Or alternatively, can this Dell's supposedly blown mobo be repaired by
replacing a known easily damaged part (that I've not found yet)?
If the PS/2 ports stop working, it is very likely the 5V
fuse has been blown. Many mobos have thermal self-resetting
fuses there, you might try that first, just let the machine
cool for a few minutes and try with a different mouse/keyboard.
If not, inspect around the ports for a fuse component. Some
mobos use picofuses, look like 1/4 W resistors, but all green.
