Yeah, my big UPS was throwing all kinds of alarms Monday evening when the storm started. So I quickly brought everything down and then unplugged everything. The UPS was the only device plugged into my house power. Everything else was running off the UPS. The Displayport to HDMI transmitter runs off usb 5 volts, that was coming from my PC, which was powered from the UPS. The POE Injector was being powered from the UPS. The UPS still checks out and is functioning. Can't explain it, except the strikes were definitely on my farm, very close to my house. My house sits on the front edge of the woods, so I do get more than my fair share of close strikes. I have had several large, mature trees, split in half due to lightning strikes in the past 25 years. I have lost several computers in the past due to lightning strikes.
Probably the strangest loss I had was a old HP PC. This was back in the days when ISDN was all the rage. Storm was coming, I was sitting in my mancave, watching TV. Computer wasn't even on. There was no lightning strikes near me, but as I was sitting there, I heard a "Snap" noise emitting from my computer and saw a tiny whisp of smoke emit from my ISDN modem. That's not good. Checked the house phone......dead. Looked at the ISDN modem......dead. Powered on my computer.........dead. A distant lightning strike hit somewhere and came down my ISDN line, arced everything inside the modem and continued into my PC and snapped some IC's on the MB. I lost a couple of TV's a few years ago, too.
