Method and system for communication between a secondary processor and an auxiliary display subsystem of a notebook
First Claim
1. A method for communication in a notebook including a secondary processor coupled to a serial bus, and an auxiliary display subsystem, the method including the steps of:
- (a) sending at least one message from the auxiliary display subsystem to the secondary processor over the serial bus; and
(b) sending at least one message from the secondary processor to the auxiliary display subsystem over the serial bus.

Abstract
A method for communication over an SMB, I2C bus, or other serial bus between an auxiliary display subsystem and a secondary processor of a notebook including the auxiliary display subsystem, and systems, circuits and notebooks configured to perform the method. Typically, communication over the serial bus between the auxiliary display subsystem and secondary processor can occur when the notebook is in a standby or other low-power state (e.g., to obtain system status data or cause the notebook to wake up) or a fully-powered normal operating state. Typically, the auxiliary display subsystem is coupled not only to the notebook'"'"'s secondary processor by the serial bus but also to the notebook'"'"'s central processing unit by another link (e.g., a USB).
