Abstract
Methods and systems are provided for power management in communication devices, particularly based on cable connectivity. A communication device that comprise a communication port, comprising a first connector and a signal path communicatively coupled between device components and the connector, may be operable, such as via a power management component in the communication device, to determine whether an external cable is mated to the first connector and to transition the communication device to a sleep mode if it is determined that an external cable is not mated to the first connector.
Claims31
A communication device, comprising:
- a communication port that comprises a connector and a signal path communicatively coupled to the connector;
- and
- a power management component configured to:
- determine whether an external cable is mated to the connector, wherein the power management component is configured to determine whether the external cable is mated to the connector based on launching a probe signal onto the signal path and measuring results of that launched signal on the signal path;
- and
- transition the communication device to a sleep mode when it is determined that the external cable is not mated to the connector.
A method, comprising
- managing power in a communication device that comprises a communication transceiver, the managing comprising:
- providing power to a sensing module;
- determining whether an external cable is mated to a connector that is electrically connected to the communication transceiver, wherein determining whether the external cable is mated to the connector comprises launching a probe signal onto the signal path and measuring results of that launched signal on the signal path;
- and
- transitioning the communication device to a sleep mode when it is determined that the external cable is not mated to the connector.
