The electronic apparatus (13) has a detector device for decoupling a signal i.e. synchronization signal, for controlling the apparatus from a control signal (15) of a computer device (10). An electronic switch processes the decoupled signal according to the control signal for controlling a switching device (17), and a time switching device sets time delay for switching on the operating voltage at a port (11) i.e. universal serial bus (USB)port. A display device displays a function status of the electronic apparatus. An independent claim is also included for a method for switching off and switching on operating voltage at a port. |
