Surface Book 3 screen shutting off when pen is passed over top bezel

Question

To be more specific, I accidentally discovered that I could cause my screen to shut off by passing the grey eraser end of my Microsoft pen over the top bezel near the camera and other sensors. Since this is a more strongly magnetized part of the pen I assume that it is magnetizing or something to some sensor there. But I believe it's reasonable to expect that the pen doesn't shut my screen off by passing over it in a certain way, especially considering it is to be stored by magnetizing to a different part of the screen. 

If I am being honest, it almost seems intentional. I recreated the shutoff a couple of times, but I am a little afraid of causing damage by doing it, so here is all I found:

-I passed the pen over the top bezel where the camera and stuff is with the flat side facing the screen/bezel, thus the side with the strongest magnetic force to it was sliding against the camera and sensors

-Passing it over makes the screen just go black for a second, then it turns back on to the lock screen, then back off until I touch the touch pad or press the power button. Touching the screen didn't seem to turn it back on.

-I was watching a video on my firefox browser with bluetooth headphones and the audio kept playing, even showing like a media control on the lock screen when it came back on. This is actually kind of awesome, as the only other way I found to keep audio playing with the screen off on this laptop was to change screen timeout settings and wait for it to automatically shut off. If I knew that this couldn't cause harm to my computer, I would use it often.

-It did do sort of glitchy flashing when the screen came back on and flashed red like my theme colour, but it was not that startling a symptom.

I would try with a different magnet but I am sort of afraid to try anything again, nevermind with another magnet. I could almost believe this was intentional, but Microsoft would definitely have let me know about it if it were.

I should put an actual question here: Is this a bad thing to do, like will it ruin my computer?

Answer 1

I just realized what is going on now. I'm so funny.

There is a magnet sensor there that shuts off the screen because that is how the screen shuts off when you close the laptop! There is a magnet just below the touchpad that activates this feature! So, therefore, it is totally safe to do! Exclamation point!

I can not actually confirm it is safe to do but I don't exactly see why it would not be. How do I mark this as solved?
