Apocryphal: user reports laptop frequently crashing. Tech is putting it through paces, can’t make it crash. Tech slides it over and asks user to show them what they do differently. User touches the laptop (before they can do anything with it) and it crashes. I was told about this, I didn’t see it happen.

I’ve heard that some laptops with magnetic closures register lid closes when someone with a magnetic wrist watch puts their hands near the keyboard!
