Reed switches are pretty damned huge when working at the scale of a laptop.

Not to mention it would make the case of the computer microphonic — bump it hard enough and that’ll be transmitted through the reed relay.

Yeah, I agree. Reed switches might even resonate with music played through laptop speakers. This needs a no-moving-parts magnetic sensor.
