The peculiar thing about having an aluminum cased laptop is that when the ground wires in the power adapter get frayed, or if the electrical circuit is hot garbage, you tend to get a little tingle when you touch the computer. Time to either throw away that adapter or get your wiring checked.
But when you feed bad power into a computer, you get glitches, and quite often this 'haunted' equipment is just running in a bad way. For all we know this woman jiggled a wire and everything is fine.
I've been on the other side of this: IT head says we're gonna swap a server out. It has nothing to do with the workload I/we have today so we say sure. Problem is that it's in the same rack as something with a deadline, and jiggling the wires causes a network connection to go down. I've had this happen three times and we've swapped the cables in each case. Because jiggling an ethernet cable should never be sufficient stress to lose connection.
First time the manager threw the cable away on his own. Second one I had to make him give me the cable because 'it could still be good'. Third one started the same argument, then pulled out wire cutters, cut off the ends, handed them to me to shut me up. Bad equipment goes in the garbage, not into a drawer that means 'ticking time bombs'. Since the connectors are usually why a cable is 'bad', I was mollified.
