Abstract: A method for performing power management in an electronic system and associated apparatus are provided, where the method is applied to at least one electronic device of a plurality of electronic devices of the electronic system. Based on the method, the electronic system utilizes a control electronic device within the plurality of electronic devices to send a first turning on signal to a first electronic device within the plurality of electronic devices to trigger the first electronic device to turn on, wherein the first electronic device is coupled to the control electronic device. The electronic system utilizes the first electronic device to send a second turning on signal to a second electronic device within the plurality of electronic devices to trigger the second electronic device to turn on, wherein the second electronic device is coupled to the control electronic device through the first electronic device.

Abstract: An electronic device includes a transmission interface and a control circuit. The transmission interface includes a signal reference contact and a signal transmission contact. The control circuit is electrically coupled between the signal reference contact and a ground layer, in which the control circuit is configured to selectively conduct the signal reference contact and the ground layer, and when the signal reference contact and the ground layer are conducted, the signal transmission contact is configured to transmit a first signal, and when the signal reference contact the ground layer are not conducted, the signal reference contact is configured to transmit a second signal. A transmission frequency of the second signal is less than a transmission frequency of the first signal.

Abstract: An electronic device includes a transmission interface, a switch unit and a control unit. The transmission interface includes a signal reference contact and a signal transmission contact. The switch unit is coupled between the signal reference contact and a grounded layer. The control unit is coupled to the switch unit. When the control unit controls the switch unit to connect the signal reference contact and the grounded layer, the signal transmission contact is used to transmit a first signal. When the control unit controls the switch unit to disconnect the signal reference contact from the grounded layer, the signal reference contact is used to transmit a second signal.
