Method and apparatus for reducing power consumption for power supplied by a voltage adapter

An apparatus for reducing power consumption of a voltage adapter connected to a power source, the apparatus comprising:

• a voltage adapter;
• and
• control circuitry, wherein the control circuitry is operable to measure a load current supplied by the voltage adapter and an output voltage of the voltage adapter and selectively disconnect the voltage adapter from the power source by a control device of the control circuitry, wherein the disconnecting is responsive to the control circuitry inferring from the measured current and voltage that the load is low based on output voltage and load current thresholds.

A computer program product for reducing power consumption of a voltage adapter connected to a power source, the computer program product comprising:

• instructions for causing control circuitry of the voltage adapter to read a first control circuitry input signal, the first control circuitry input signal being responsive to measuring a load current supplied by the voltage adapter, and to read a second control circuitry input signal, the second control circuitry input signal being responsive to measuring an output voltage of the voltage adapter;
• and
• instructions for causing the control circuitry to selectively disconnect the voltage adapter from the power source, wherein the disconnecting is responsive to the control circuitry inferring from the measured current and voltage that the load is low based on output voltage and load current thresholds.
