Abstract: The present invention is directed to the detection of faulty CPU heat sink coupling during system power-up. A method in accordance with an embodiment of the present invention includes: monitoring a slope of a CPU temperature rise from initial system power-up; determining if the slope of the CPU temperature rise exceeds an expected value; and in the case that the slope of the CPU temperature rise exceeds the expected value, indicating an existence of a possible fault (PFA) related to a heat sink coupled to the CPU.

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.
