[conspire] Computer Gremlins -- bad AC power?

[Dana Goyette]

Thanks for the tips about weak neutral!  I told my dad (he owns the place) about it, and he said he'll take care of calling PG&E to have them come check it out.

I had called Comcast out due to the cable being out and after checking it, the tech said that their cable had literally melted off the side of the building.  He said that when he pulled the burnt cable off there was a big spark and he was unable to repair it.  He said he had reported it to PG&E and they would be out sometime that week.  I had also noticed the voltage meter on my UPS showing voltages ranging between 80 and 140 volts!

PG&E had a truck outside and a guy up the pole within the hour!  It turned out to be a faulty ground which was quickly repaired and has been fine ever since.  Comcast came back the next day and replaced their cable which took care of the connectivity problem.
