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).
