ABSTRACT:
A data processing system and method are disclosed for disabling a portable computer in response to the portable computer being moved outside of an authorized area of use. An authorized, geographical area of use is established. The authorized, geographical area is any geographical area capable of being defined. The geographical area is not limited to areas within an enclosure, and is not bounded by a transmitter's broadcast range. A determination is made regarding whether the portable computer is located outside of the authorized area. If the portable computer is moved outside of the authorized area, the portable computer is disabled. The portable computer is inoperable when disabled.
