ABSTRACT:
The present invention provides a personal computer system for receiving and retaining data and capable of securing data retained within the system against unauthorized access. More particularly, the system includes a computer including a processor and a detachable input/output (I/O) device that functions as a conventional computer interface when docked to the computer and wherein the computer system enters a suspend mode when the detachable I/O device is detached from the computer whereby the system data is secured against unauthorized access. A security module controls access to at least certain levels of data retained within the system by distinguishing between the detachable I/O device docked to the computer and the detachable I/O device detached from the computer. A docking station is coupled to the processor and is detachably coupled to the detachable I/O device. The detachable I/O device is, for example, a detachable trackpad or trackball I/O device and the docking station includes a sensor for detecting when the detachable I/O device is docked to the computer.
