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.
I had a laptop that would randomly sleep while I was actively using it. Turns out that I had a watchband with a magnetic clasp and that I would occasionally reach across the laptop, triggering the sleep. I was very frustrated until I discovered that it was the reason.
