摘要： Systems and methods are disclosed for positioning an antenna in a portable information handling system. A portable information handling system includes a housing having a first housing portion and a second housing portion. The portable information handling system also includes a hinge assembly rotationally coupling the first and second housing portions. The portable information handling system also includes an antenna disposed within the first housing portion, the antenna operable to transmit radio waves. The portable information handling system further includes an antenna aperture formed within the first housing portion. The second housing portion comprises a radio frequency (RF) permeable region comprising RF permeable material, the RF permeable region located in proximity to the antenna aperture when the portable information handling system is in tablet mode, tablet mode representing the first housing portion rotated approximately 360 degrees from the second housing portion.

摘要： A display in a portable information handling system may have a narrow or no border. A light guide for display light enhancement used to illuminate the display may be formed with concave indentations at a first face that receives light from a light source, such as a string of light emitting diodes. The concave indentations may improve the homogeneity of light transmitted by the light guide. The light guide may further have a light diffusive surface treatment at the first face.

摘要： Methods and systems for securing data processing systems are disclosed. A data processing system may be operably connected to other devices via ports. When operably connected, some devices connected via the ports may cause undesired actions to be performed. To limit physical access to the ports, a security apparatus may be used to lock the ports. The security apparatus may transition between states where it may be inserted into openings for the ports and may be locked to the openings for the ports. When so locked, physical access to the ports may be limited.
