ABSTRACT:
One embodiment of the present invention provides a system for generating an alarm in a portable computer system. In this embodiment, when an owner of a portable computer system determines that the portable computer system is either stolen or missing, the owner activates a remote transmitter. This remote transmitter sends an activation signal to a receiver in the portable computer system. In response to the activation signal, the portable computer system takes at least one theft deterrence action, such as generating an audio alarm. In one embodiment of the present invention, the theft deterrence action includes erasing at least part of the contents of a data storage device in the portable computer system. In another embodiment, the theft deterrence action includes disabling power for the portable computer system. In yet another embodiment, the theft deterrence action includes dialing a telephone number through a mobile telephone coupled with the portable computer system.
