An interlock enables power to a computer component to be disconnected prior to removal of the component from an access port. Actuation of a latch enables an operator to move the interlock away from the access port of a computer housing. Movement of the interlock away from a computer housing removes communication of the interlock with a power switch of the associated access port and thereby removes power to the associated access port. In addition, movement of the interlock away from the housing enables an operator to remove and/or place a component in the access port. Similarly, proper placement of the interlock in front of the access port places the interlock in communication with a power switch of the associated access port and provides power to the associated access port, and prevents actuation of an ejection lever of the access port.

A system for assembling electronic work stations including multiple electronic units. The electronic units are provided as subassemblies, premounted into specially formed trays. Special slide engaging male and female mounting components have one of the components formed into the chassis and the other component formed into the tray. The subassemblies are simply slid into place and various locking means are automatically engaged as the subassemblies are forced into their "home" position. The assembly time is greatly reduced resulting in substantial savings.

A computing device includes a charging coil for producing a charging current when placed in a magnetic field of a wireless power transmitter. A wireless charging operating frequency is associated with wireless charging of a battery of the computing device by the charging coil and the wireless power transmitter. An electrically conductive substrate has a plurality of gaps for reducing eddy currents when the electrically conductive substrate is disposed between the charging coil and the wireless power transmitter during charging of the battery. A plurality of filters each electrically bridge a respective one of the gaps. Each filter attenuates signals within a range of frequencies including the wireless charging operating frequency.
