Abstract

A technique is described whereby a mechanical locking mechanism is attached to the rear of a personal computer to prevent unauthorized access. The security lock mechanism provides three functions; a) to prevent turning on power, b) to prevent removal of cover screws, and c) to prevent removal of the monochrome display. Lock frame 10, as shown in Fig. 1, is mounted at the rear of the computer, secured by four screws 11, two cover and two power supply screws, bolted from the inside. Lock cover 12, as shown in Fig. 2, is mounted over lock frame 10, held by lock cover holding screws 13. Key lock 14 is mounted on lock frame 10 so that when lock plate 15 is inserted into slot 16, lock tab 17 is turned by a key to engage into slot 18, preventing removal of the lock plate 15.
