I couldn't imagine this happening. Friday was very hot, and our power company decreased the voltage in a "rolling brownout." I took a lot of damage to my appliances. But what totally amazed me is that my video card is now not working, and I am only slightly less amazed that the logic board on my garage-door opener needed to be replaced.
Why is low-voltage equipment not designed to survive an under-voltage? I can understand being fried by a lightning strike, but a ten percent drop in voltage? Can anyone explain to me why electronics aren't built to survive this?
To make matters worse, the computer whose video card failed was on a UPS. I test the UPS monthly. The UPS was alive on Saturday, but has failed since then. Not just a dead battery - it can't pass power through and I had to plug everything into a simple surge preventer.
The good news is that the power company may pay for all the damage. But why on Earth should lower voltage break things? It's like (but, I know, the opposite of) when the Enterprise is hit by enemy fire and sparks shoot out of the console and knock extras unconscious. Haven't they heard of circuit breakers / fuses?
(oh, fooey. My custom smileys are gone. I had one of hitting the computer with a mallet. Imagine it here.)
