Abstract
An electronic device (100) includes a network interface controller (102) and an input/output controller (110, 202) having a link layer. A portion of the input/output controller is configured to be powered off during a lower power mode of the electronic device, where the first portion contains the link layer. Wakeup logic (108) separate from the input/output controller receives a wake indication from the network interface controller in response to the physical layer receiving a wake message on the network while the electronic device is in the lower power mode. The wakeup logic activates an indication to awaken the electronic device from the lower power mode in response to the wake indication from the network interface controller.
