Power goes out at a law firm, and the UPS immediately starts beeping as an alert that it is discharging. One woman working nearby finds the beeping annoying, and she turns off her PC in an effort to make it stop. That does nothing about the beep-beep-beep, of course, but she’s been driven to distraction and starts to shut down everything in the law firm. The beeping continues. So she goes to the source and unplugs the UPS.
Yes, reader, you know the result: beep-beep-beep! But she cannot understand how the UPS can continue howling without a source of power. (Ahem! We are well aware that it has had no external source of power for quite some time at this point, but remember, the beeping is truly driving this poor woman around the bend.) “We thought it was possessed!” she exclaims to pilot fish.
