I have most of my electronics sitting on UPS. Just a couple of nights ago, I was downstairs watching a movie on Netflix and there was a small bounce in the power. enough that it upset the lights, the clocks on the stove, microwave etc went out. But the TV and AV were not effected and I just got the small annoying beep to tell me that something happened.
