A method of supplying power, data and/or cooling with a single cable, including the steps of:
- using a wall receptacle which has input/output ports for power and data;
- using a multifunction power/data cable to carry power between a wall receptacle and an electronic device via internal power lines which carry power from the wall receptacle to the electronic device;
- and
- using the multifunction power/data cable to carry data between the wall receptacle and the electronic device via internal data lines which carry data between the wall receptacle and the electronic device;
- whereby both electrical power and data is delivered to a wall receptacle and a single power/data cable is used to transfer both the electrical power and the data between the wall receptacle and the electronic device.
