Abstract

A portable information handling system housing biases to the closed position by attracting a piece of ferromagnetic material disposed in a lid housing portion to a magnet in a speaker disposed in a main housing portion. A Hall sensor proximate the ferromagnetic material detects the speaker magnet in the closed position and communicates open or closed position detection through a flexible cable and hinge to an embedded controller in the main housing for execution of logic associated with open and closed positions, such as ACPI sleep and wake states.
