ABSTRACT:
A computer uses an optical reflective optical sensor to detect the removal of a cover of the computer housing. The reflective optical sensor includes a light emitter and a light detector, and is mounted adjacent a reflective surface on the inner side of the cover when the cover is in place such that the light emitter is reflected by the reflective surface and received by the light detector. When the cover is removed, the intensity of the reflected light received by the light detector drops. The change in the output of the light detector triggers the operating system of the computer to power down the computer.
