An information handling system includes a printed circuit board, a screw, and a processor. The printed circuit board includes a through hole via. The through hole via includes top and bottom sections plated with a conductive plating material, and a middle section without any conductive plating material. The screw is in physical communication with the top, middle, and bottom sections of the through hole via in the printed circuit board. The processor determines whether an electrical circuit is formed between the screw, the top section of the through hole via, and the bottom section of the through hole via. Based on the determination of the electrical circuit being formed, the processor provides an indication that no intrusion has been made into the information handling system.

An information handling system printed circuit board includes solder pads that accept footprint compatible integrated circuits, such as charger integrated circuits that provide power with different choke circuit supporting components. Solder pads for supporting components include first and second conductive areas sized to accept a first supporting component, each of the first and second conductive areas including an intervening non-conductive area that manages positioning of a smaller second supporting component at solder reflow.

A switching module capable of adjusting a visual angle is disclosed. The switching module includes an edge-type optical substrate, a light source disposed by a side of the edge-type optical substrate, and an optical modulating component disposed between the light source and the edge-type optical substrate. The edge-type optical substrate has an emitting surface. The light source includes a plurality of light units. Each light unit can emit a beam to the edge-type optical substrate according to a predetermined angle. The optical modulating component can modulate divergence of the beam emitted from the light unit, so that the beam can be guided out of the edge-type optical substrate via the emitting surface according to the predetermined angle.
