A power controller contains a protective lockout function that might have tripped on that anomaly. This lock out is reset by unplugging long enough for any 'computer off but LED still lit' light to extinguish.The power went out, came back on for about 2 seconds, went out again, came on for a few more seconds and then went off again for a few hours.
Hi dtravis7,
Actually there was no thunderstorm or lightening. Someone apparently ran into a power box......
