ABSTRACT:
A pen-based portable personal computer utilizes a passive stylus. In order to conserve battery power, the system automatically goes into a low-power state after a predetermined period of inactivity. In the low-power state, minimal power is provided to a digitizer panel in order to enable the digitizer panel to sense contact by the passive stylus. Once the passive stylus comes in contact with the digitizer panel, the pen-based portable computer system is awakened and placed in a full-power state.
