Why does a laptop need an orientation sensor
Every laptop for the past few decades has an orientation sensor. It's a standard part of the screen, since people generally want their laptops to sleep when you close them.
I think that's usually done with capacitive sensing.
Or hall effect sensors (Lenovo laptops use this, I have set them off a few times with magnetic watch band clasps)
