Abstract
A switching device is provided for determining to which parts of a notebook computer an electrical power is delivered. The switching device is used in a notebook computer having an independently operating media module. The switching device is located at the output terminal of the notebook computer's power supply and, based on a control signal, determines the parts of the notebook computer to be powered. The independently operating media module, under an effect of the switching device, can directly play a video signal on the notebook computer's LCD display and speakers without powering on the notebook computer and booting up its operating system.
