ABSTRACT:
A portable computer and method of providing security for an electronic device are described. According to the method of the present invention, a security device disposed within a first electronic device is armed. The security device, which has at least a first mode of operation, detects whether or not a second electronic device is within a selected proximity of the first electronic device. In response to a detection that the second electronic device is not within the selected proximity of the first electronic device, a signal is generated indicating that a security violation has occurred. In one embodiment, wireless signals having an effective range equal to the selected proximity are transmitted from the second electronic device to the first electronic device. The security device determines that the first electronic device is not within the selected proximity of the second electronic device in response to a failure to receive the wireless signals.
