One or both of the machines has a open or faulty ground. Try a continuity
/ low ohms / lamp test between each ground pin on the plug and the system
chassis. Probably a power cord fault, though it could also be a faulty
socket strip.

All machines with switched mode psu's *must* be grounded for safety - they
often have high leakage currents...
