Re: Seen in the wild
Of course, there's the dreaded evil twin of the loose power cable: the power cable that's only just in and which falls out when you adjust a nearby cable.
I've encountered it several times before, including just a few days ago whilst moving power cables into a new UPS, my hand brushed the input for the old UPS.
Cue a slight crackling noise, and the unsettling *clunk* as it tried to power everything from a very poorly battery, ran out of capacity in half a second, and clunked offline.
A quick shove and the power cable was seated properly again (seriously, how did it last 10+ years with the power cable only barely plugged in?), but the damage was done. One old, single PSU'd, machine was already rebooting, causing all sorts of issues.
