Placing a Framework 13 on top of another

When placing a Framework 13 on top of another Framework 13 laptop, the screen will turn off. How come?

I wonder if it's detecting a magnet at the front edge from the closed lid of the notebook underneath, telling the system on top that the lid is closed?
- That sure seems likely. A neodymium waved around in the right place would confirm.
- 95% this. I've done the same thing with my lenovo when I pushed it up against my speaker.
- The magnet on my watch band makes my Framework 13 go to sleep sometimes. It was so annoying I got a different band.
- weird, the laptops I've seen have magnets on the palmrest instead of the bezel, I guess it's just reversed on the framework?
  
  The bezel is attached with magnets so you can change it out for another color (or access the webcam module easily). So that'd probably be why.
The sensor that recognizes if the laptop is closed sits on the left, next to the audio jack. If you get a magnet within 2-3 cm of it, it triggers and the screen turns off. Seems like the magnet in the lid of the other laptop is just close enough.
- Seems like a fun prank. Couple strong magnets under someone's desk and now their desk is cursed. What fun
- Yep, there’s a hall-effect sensor in there. My watch band does the same thing to several laptops. Pretty annoying but not really a problem.
In this thread:
Happens with other laptops i have too. Figuring a magnet or something in the bottom laptop is triggering the top one to think the lid is closed.
Seems to me that it is likely due to the magnets on the hinge of the bottom laptop connecting with the bottom part of the top laptop. The top laptop then treats it as if the lid is closed.
- That make sense. I never knew that's how a laptop knew the lid was closed. TIL!
This is not just a framework thing. Have you ever wondered how a laptop knows that the lid is closed? Its magnets. The laptop has a magnet triggered switch in it that turns off the screen when the lid is closed. When you stack them you put the top laptop in range of the bottoms magnet triggering the reed switch in the top laptop turning off the screen.
🧲, my Samsung tablet does the same thing when flipping the magnetic lid around the back. The screen shuts off and it's annoying and it's the official cover.
Interesting feature!
@meldrik Guessing magnetic lid switch.
- Thanks! Now I feel silly :P
