A computer plug-in card 20 provides an anti-theft function. Power to the hard-drive 23 is routed through the plug-in card. If programmable security conditions are not met, the power to the hard-drive is cut, and an alarm sounds. Conventional security features, such as a motion-detector, pull-out-cord, etc, can also be included. A battery is provided on the plug-in card, and the security features remain available even when the computer is switched off. |
