Abstract: A security mechanism is provided, for use with portable equipment, such as a “notebook” type portable computer, which is to be coupled for use with stationary equipment, such as a port replicator or docking station. The security mechanism includes locking structures, located in complementary positions on the computer and the port replicator, for engaging each other to prevent theft by removal of the computer from the port replicator. The locking structures on the computer are standardized across a line of different computer models, so that the security mechanism is operative regardless of which of the different computer models is docked. Specifically, the locking structures of the various computers within the line of products are in corresponding positions on the computers, relative to the positions the computers occupy when docked. Therefore, the locking structures engage the same way, regardless of which computer of the line of products is docked.

Abstract: Radio frequency emissions within a computer system having a printed circuit assembly in proximity of a metal surface are reduced by the placement of one or more lossy components electrically connected to a metal plane within the printed circuit assembly. A connector electrically connects the lossy components to the metal surface. In one embodiment, the lossy components include two resistors at opposite ends of an edge of the printed circuit assembly that is closest to the metal surface. In an alternate embodiment, a single lossy component is a resistor placed in the middle of an edge of the printed circuit assembly that is closest to the metal surface.
