Utilization of shared wake pins in computing devices

A computer-implemented method, comprising:

• receiving, at a shared wake pin of a computing device that is operably connected to first and second external devices, a wake signal;
• responsive to receipt of the wake signal at the shared wake pin, facilitating, by logic associated with the computing device, transition of the computing device from a first state in which the computing device consumes a first amount of power to a second state in which the computing device consumes a second amount of power that is greater than the first amount of power, wherein the second amount of power is less than a third amount of power consumed by the computing device when in a third state;
• responsive to receipt of the wake signal at the shared wake pin, sending, by the logic associated with a computing device, an instruction to the first external device over a communication bus to which the first external device is connected and the second external device is not;
• and
• determining, by the logic associated with the computing device, whether the first or second external device initiated the wake signal based on a response at the shared wake pin.

A package, comprising:

• one or more processors;
• a memory operably connected to the one or more processors;
• a shared wake pin for operable connection to first and second external devices;
• an inter-integrated circuit bus to which the first external device is operably connected and the second external device is not;
• and
• a logic configured to be operated by the one or more processors to transition a computing device in which the package is installed between a first state in which the computing device uses a first amount of power and a second state in which the computing device uses a second amount of power that is greater than the first amount of power;
• wherein responsive to receipt of a wake signal at the shared wake pin, the logic is configured to transition the computing device from the first state to the second state, send an instruction to the first external device over the inter-integrated circuit bus, and determine whether the first or second external device initiated the wake signal based on a response at the wake pin.

At least one non-transitory computer-readable medium having computer-readable code embodied therein, the computer-readable code configured to enable a computing device, in response to execution of the code, to:

• receive, at a shared wake pin of the computing device that is operably connected to first and second external devices, a wake signal;
• responsive to receipt of the wake signal at the shared wake pin, facilitate transition of the computing device from a first state in which the computing device consumes a first amount of power to a second state in which the computing device consumes a second amount of power that is greater than the first amount of power, wherein the second amount of power is less than a third amount of power consumed by the computing device when in a fully operational third state;
• responsive to receipt of the wake signal at the shared wake pin, send an instruction to the first external device over a communication bus to which the first external device is connected and the second external device is not;
• and
• determine whether the first or second external device initiated the wake signal based on a response at the shared wake pin.
