1. A method of operating a media equipment device having at least a full-power mode and an off-power mode of operation, the method comprising:

  • receiving by a power supply interface in the media equipment device a voltage supply from a computer-controlled voltage source electrically coupled to the power supply interface of the media equipment device;

    receiving a user-programmable schedule of intended use of the media equipment device;

    detecting that a first threshold condition for automatically transitioning the media equipment device into the off-power mode is met based on the user-programmable schedule indicating that the media equipment device will be unused for at least a threshold duration;

    determining an amount of time for restoring at least a portion of program schedule information to the media equipment device when the voltage supply is reconnected to the media equipment device;

    calculating a scheduled power-up time to be a time at which a next scheduled use of the media equipment device occurs, offset by the amount of time for restoring the portion of the program schedule information;

    storing the scheduled power-up time for automatically restoring power to the media equipment device in the future;

    sending a power-off notification to disconnect the voltage supply to the power supply interface of the media equipment device; and

    automatically disconnecting the voltage supply to the power supply interface of the media equipment device by the computer-controlled power source, thereby transitioning the media equipment device into the off-power mode such that the media equipment device receives substantially no external voltage.
