ABSTRACT:
In electronic devices containing microprocessors, including data processing systems, logic is loaded to storage registers within a microprocessor or other suitable non-volatile storage medium during the manufacturing process. The logic provides for detecting the presence of a battery employed to power an interval timer. Also, the logic provides pre-set time intervals that operate in conjunction with the interval timer and existing or installed device state sensing devices. One time interval provides a warning to a user that the protected device will be deactivated within a specified period of time if a preset authorization code is not entered into the device. Another interval is provided to carry out deactivation if the preset code is not entered. Types of automatic deactivation include: partial deactivation, which comprises allowing communication via modem with a service center to obtain authorization; fully deactivated state requiring entry of a key code to reactivate the device and destructive deactivation which destroys circuits within the device necessary to operation.
