This story has been called in by a very choshuve yid by the name of Shmuel Laniado. His son came over to him and said, “Tatty, my laptop hasn’t been working already for the longest time. When I plug it in, the light doesn’t go on, and it doesn’t work.” R’ Laniado said, “Let me try,” and he tried plugging it in here and he tried plugging it in there, but it seemed like it was simply broken. R’ Laniado said, “Should we get a new one?” Then he said, “There’s no such thing as ‘broken’; let’s just be mechazek and sing together ‘Hakol Yachol.’” R’ Laniado told his son, “Now let’s try again.” They plugged it in, and this time it worked!
