  • Patent number: 10777857
    Abstract: A portable computer may include battery indicator light structures. Battery status information in the portable computer may be presented to a user using an array of light-emitting diodes or other light emitters. Light-emitting diodes may be mounted on a printed circuit board. A stiffener may provide the printed circuit board with rigidity. The printed circuit board may include a connector that allows the board to be connected to a main logic board. A switch on the printed circuit board may be actuated by a power button on the portable computer. An opaque member with an array of holes may be used to reduce light bleed between adjacent light-emitting diodes. Diffusing plastic may be mounted within the array of holes. Bumps in the diffusing plastic may mate with corresponding holes on a portable computer housing.

  • Publication number: 20190220065
    Abstract: This application relates to hidden fasteners within an electronic device. An electronic device can include a top portion and a base portion that includes a housing and a cover attached to the housing by at least one fastener that is not visible through an external surface of the cover. Each fastener includes a receiver housing that retrains spherical components and a pin that can be inserted into an opening in the receiver housing. The pin is retained in the receiver housing by a force imparted against a surface of the pin by the spherical components, which are biased towards an inner surface of the receiver housing sloped towards the opening. The pin can be released when an external magnetic field from a magnet placed proximate the bottom surface of the receiver housing retracts the spherical components away from the opening, thereby reducing the force against the surface of the pin.
