Abstract
A method of controlling power consumption of a power supply of a device may include receiving a control signal that switches the device between first and second modes of operation; and switching the supply between corresponding first and second modes based on the received signal, the supply being configured to draw different amounts of power in the first and second modes. A power supply for supplying electrical power to a device may include power supply mode circuitry configured to place the supply into one of at least two power modes: a first mode in which the supply draws a first amount of power and a second mode in which the supply draws less power. An electronic device may include circuitry that generates a control signal, based on which the power supply mode circuitry selectively places the electrical power supply into one of a plurality of power modes.
