Abstract
Method and apparatus for transitioning an electronic device operable in a reduced power consumption mode from the reduced power consumption mode to a full power mode immediately before a user attempts to operate the device is disclosed. A hand held intelligent data entry unit (IDEU) of the present invention is provided with a noncontact sensor for detecting the prepense of a user's hand within an predefined actuation region of the IDEU while the IDEU is operating in a low power consumption mode. Responsive such detection, the sensor generates a wake up signal to a microprocessor of the IDEU for causing the IDEU to transition from the low power consumption mode to a full power mode.
