    Abstract: An electronic device can include first and second housing components and an electrical grounding feature located therebetween to provide a grounding path. The grounding feature can include an outer portion formed from an electrically conductive material and an internal region containing a removable expansion element. The grounding feature can exert an expansion force against the housing components when the device is assembled and the expansion element remains, and exert no expansion force against the housing components when the expansion element is removed. The device can also include an adhesive coupling the electrical grounding feature to the housing components, which adhesive can be electrically conductive. The expansion element can be deformable and removable from an open end of the grounding feature outer portion, which outer portion can be elastic and can deform to contact more of the housing components when the grounding feature is compressed therebetween.

    Abstract: A portable computing device that includes a base portion that carries an audio module and a display housing that carries a display is disclosed. The display housing is coupled with, and rotatable with respect to, the base portion. The display housing includes a magnet, and the base portion includes a magnetic field sensor that detects an external magnetic field of the magnet. The magnetic field sensor provides a signal that deactivates the display. In order to reduce layout changes in the portable computing device, the magnetic field sensor is positioned in an audio housing that carries the audio module. However, the magnetic field sensor is designed and oriented to detect the magnetic field from the magnet in the display housing and effectively ignore magnets associated with the audio module. In order to reduce the amount of electrical connections, the magnetic field sensor is electrically coupled to the audio module.
