Abstract

Power supply equipment is provided for supplying an appropriate power adapter identification signal, as well as DC power, to various types, brand and models of electronic devices. The equipment includes a power adapter having conversion circuitry for converting power from an external power source to the DC power utilized by a particular electronic device. The power adapter also includes circuitry to generate a plurality of power adapter identification signals. Selection circuitry, responsive to user selection or to the configuration of a cable, connector or connector adapter included with the power supply equipment, selects a particular one of power adapter identification signals appropriate for the particular electronic device. The selected power adapter identification signal and the DC power are transferred to the power input port of the electronic device.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method of providing power to an electronic device comprising:
 detachably mating an output connector to the electronic device;   selecting a power adapter identification signal generated by one or more power adapter identification circuits, for transmission to the electronic device via the output connector;   sending the selected power adapter identification signal from the power adapter identification circuit to the electronic device via the output connector;   selectively transmitting DC power to the electronic device via the output connector based on the selected power adapter identification signal.   
     
     
         2 . The method of  claim 1 , wherein the power adapter identification signal is selected by the user. 
     
     
         3 . The method of  claim 1 , wherein the power adapter identification signal is selected by the configuration of a cable, output connector, or output connector adapter. 
     
     
         4 . The method of  claim 3 , wherein the configuration of the cable, output connector, or output connector adapter selectively determines the transmission of a code which is sent from the output connector to a switching mechanism in the power adapter identification circuit.
