    摘要： A portable information handling system battery module has a self-contained housing having a battery charger, integrated rechargeable batteries and plural ports to transfer power, such as USB Type C ports having bi-directional power transfer capability. A cable couples first battery module port to a portable information handling system port to provide power to the portable information handling system and accept power from the portable information handling system. Plural additional battery modules daisy chain to the first battery module to accept power from and provide power to the portable information handling system. Power transfer is coordinated with communications through the ports, such as by a USB power transfer protocol supported at the information handling system and each battery module.

    摘要： An information handling system provides power to a peripheral through a peripheral interface, such as a USB interface, by communicating power availability with a primary set of power parameters through a data link and communicating power availability with a secondary set of power parameters through a power link. If a peripheral device has the capability to draw power at the second power parameters, it does so while monitoring for a fold back of host power that indicates power is not available at the second power parameters.

    摘要： 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.

    摘要： Systems and methods for a dynamically reconfigurable touchpad are described. In an illustrative, non-limiting embodiment, an Information Handling System (IHS) may include processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the IHS to: receive a configuration parameter from a user; and modify a touchpad by applying the configuration parameter to the operation of proximity sensors disposed under a non-display surface of the IHS.
