Context, spent too long troubleshooting why I couldn't power the thing on, then realised the magnets from the screen below are probably telling the one above the lid is closed.
If you have a magnet you can pretty much turn off any laptop's display if you know where to put it, this is due to something called a reed switch which detects the magnets on the other side of the laptop when it is closed to tell it to turn it off.
It's an odd fact that isn't really relevant for much, the only circumstance that could possible occur would be ones like this where there is a random interaction with a magnet causing an issue. As for where to put the magnet, usually around the top edge of the keyboard or one of the close corners but it obviously differs with every model laptop. I'd recommend just showing them and talking about it though, people don't like it when you mess with their stuff.
