Abstract
A system includes a power supply and a power switch to connect an external power source that is external to the system to the power supply. The power switch has an on position and an off position. The power switch if actuated to the off position causes the system to be electrically isolated from the external power source. A control circuit is responsive to actuation of the power switch to provide a signal to cause software control of a power state of the system.
