What appears to be a curious trick – placing an AirPods case near a Chromebook and watching the screen turn off – is in fact a straightforward application of the Hall effect. Modern laptops employ Hall effect sensors near the hinge to detect whether the lid is open or closed. A constant current flows through the sensor, and when a nearby magnet is introduced, its magnetic field deflects the moving charge carriers. This deflection generates a measurable voltage, which the laptop interprets as the lid being closed. In this case, the magnet embedded in the AirPods case mimics the lid magnet, causing the Chromebook to enter sleep mode.

Are you a girl or boy?
99% of this channel are things that I already know. But Im watching it mostly for making support – every view counts, especially when one movie was watched multiple times by one user.
Such basic things should be as a topics in basic schools, but they are not.
Thanks bro
Happened to me accidentally, but i also quickly realized why
one time someone in class had a magnet and they just reached over and put the magnet right next to the sensor, not even a warning
Forbidden Knowledge 🙈
If the intent is to lock the computer Win+L
If the intent is to put laptop to sleep, you can use the sleep button, or change setting to tell simple press on power button goes to sleep
im pretty sure that its the hinge angle that makes a Windows device go to sleep
The way she said "UNLESS" 🥺
LOL 😆
