Information Handling System External Adapter and Battery Source
First Claim
1. A portable information handling system comprising:
- a housing;
a processor disposed in the housing and operable to execute instructions to process information;
a memory disposed in the housing and interfaced with the processor, the memory operable to store the information;
a display disposed in the housing and interfaced with the processor and memory, the display operable to present the information as visual images;
a power controller disposed in the housing and operable to accept external power and provide the external power to the processor, memory and display;
a port interfaced with the power controller and configured to accept a cable having power provided from an external power source;
controller module having a cable configured to couple with the port, the controller module including a power controller circuit operable to coordinate power transfer with the power controller; and
a power source module removeably coupled to the controller module and interfaced with the power controller circuit, the power controller circuit controlling transfer of power between the power source and the port.

Abstract
A portable information handling system power source has plural separate modules that removeably couple to each other to selectively provide external power from battery and AC power sources. A controller module includes logic to coordinate power transfer to and from an information handling system. An AC-to-DC adapter module couples to the controller module to provide power from an AC power source to the information handling system through the controller module, which coordinates power transfer with the information handling system. A battery power source module couples to the controller module to provide battery power, with the battery charged by power from either the information handling system or the AC-to-DC adapter module.
