Abstract: An improved bezel release mechanism for a computer includes wedges, which move laterally over clips on the bezel and apply a downward force on clips when a button coupled to the wedges is pushed. The downward force releases the clips from features on the chassis, disengaging the bezel. In this manner, the bezel release mechanism is toolless and allow for the efficient removal and recoupling of the bezel. Since the bezel release mechanism resides within the chassis and requires the removal of a side door to access it, it also provides protection against accidental or malicious operation.

Abstract: A computer has at least one adapter card slot for receiving an optional adapter card. A cover plate is rotatable hinged and has open and closed positions. In the closed position, the cover plate covers the adapter card slot and inhibits the insertion or removal of an adapter card. When the cover plate is raised into the open position, a tab on the back of the cover plate is rotated out of the slot of an optical switch, and the optical switch then signals circuitry to remove power and bus signals from the adapter card slot; thereby permitting the adapter card to be removed from or inserted into the slot without removing power to the entire computer. When the cover plate is returned to the closed position, the tab is reinserted into the slot of the optical switch, which in turn signals the circuitry to return power and bus signals to the adapter card slot.
