Guy lives in Oakland. Their power fluctuates pretty badly, late at night, much like Berkeley.
Ours seems to go off same time every two weeks, 7AM for some reason. Wiring in these buildings is from about 1965. Not so good.
I plugged the UPS into the Voltage Regulator.
I think I'll suggest the guy runs a Voltage regulator. Besides literally melting his motherboard, he has also managed to break a UPS. NO led display, no dead battery, just broke it.
