When the computer is turned off with the power button on the front panel, the power
consumption falls below 3W, but it is not zero. The special on/off method used by these
computers considerably extends the lifetime of the power supply. To reach zero power
consumption in “off” mode, either unplug the power outlet or use a power block with a switch.
