Abstract
Methods and systems are provided for power management in communication devices, particularly based on cable connectivity. In a communication device that includes a communication port, including a first connector and a signal path communicatively coupled to the connector, measurements associated with the signal path may be obtained. Based on the obtained measurements, it may be determined whether an external cable is mated to the connector, and the communication device may be transition to a sleep mode when it is determined that the external cable is not mated to the connector. Determining whether the external cable is mated may be based on detecting presence or absence of a signal on the signal path, based on evaluating signal characteristics of a signal present on the signal path, measuring of voltage or current at the communication port, and/or energy measurements associated with one or more particular frequencies.
