I never heard about it before I ruined my computer. I am surprised so many people know. I brought it up once on a FR “computer” thread, and, like you, everyone said...oh yea, I unplug my computer! lol
What’s silly is that I always turn the rocker switch off on the surge protectors, too - right before I unplug them! Duh.
When I plug back in and nothing turns on automatically, I always worry for a second - then turn the darn things back on. It’s silly, but I have done it every time.
At least I finally learned to leave the lamp on a separate strip and plug, so I could still see!
