Yeah.
And I can’t tell if the UPS is toast, or if it is just the battery.
I'll never forget the one at my office which passed into the realm of the toasted one Monday morning a couple years ago. We knew there had been a power outage in the building sometime over the weekend, and the phone system was giving us some trouble (which was nothing new) and our office lady and I went into the server room to investigate. She, a middle aged woman of very proper and calm demeanor was standing right next to the UPS at the very moment all of the smoke and flames which are normally kept locked safely in such devices, chose to make a rapid escape.
I saw another side of our lady that day.
