1. A computing device comprising:
a communication interface configured to receive link pulses from another computing device over a communication link, wherein the link pulses correspond to a burst of pulses transmitted by the other computing device to the computing device;
an energy detection circuit configured to change a state of a link light emitting diode (LED) associated with the computing device in an instance in which an energy of the link pulses is greater than a threshold energy level;
a wake-up detect circuit configured to detect the change in the state of the link LED associated with the computing device, wherein the wake-up detect circuit is configured to:
in response to the detection of the change in the state of the link LED, transmit a wakeup trigger signal to a processor to transit from a sleep mode to a wake-up mode; and
wherein the processor is configured to:
in the wake-up mode, establish a connection between the computing device and the other computing device via the communication link, wherein the other computing device corresponds to a device that has caused the change in the state of the link LED by transmitting the link pulses.
