ABSTRACT:
Systems and methods for interfacing a battery system of a battery-powered keyboard system with main battery components of a battery-powered information handling system to enable a battery charging system of the battery-powered information handling system to charge both the main battery pack of the battery-powered information handling system and the battery pack of the battery-powered keyboard system without the presence of a separate stand-alone battery charger in the battery-powered keyboard system, and/or so that the keyboard battery of the battery-powered keyboard system may be used to supplement the main battery of the battery-powered information handling system such as in case of emergency power loss or to extend total battery life for running the information handling system.
