Abstract: A battery pack includes a housing. A first battery is located in the housing, the first battery using a first cell technology. A second battery is located in the housing, the second battery using a second cell technology that is different from the first cell technology. The battery pack can be connected to a portable computer chassis to provide an extended life power source.

Abstract: Audible noise related to power state transitions of an information handling system processing component, such as the central processing unit, is reduced by randomizing the time between power state transitions. Random power state transitions are managed by an operating system module that tracks the transitions and selects random times for subsequent transitions within a predetermined time range. Alternatively, an arbitrating circuit intercepts power state transition commands and arbitrates their communication at random times. Random power state transitions reduces audible noise by spreading the frequency of the noise-causing power transition events over a wider band.

Abstract: Systems and methods for providing an extended battery system for a docking component such as a media slice. The extended battery system may be a high capacity battery system provided to power components of the docking component and to provide a relatively longer battery life than a conventional non-high capacity battery system. The docking component may be configured to be capable of charging the extended battery system, and/or the extended battery system may be configured so that it is also capable of use with a portable information handling system (e.g., notebook computer) that is configured for docking with the docking component. The extended battery may be configured as a frontal extending battery system for use with a docking component and/or portable information handling system.

Abstract: A battery pack includes a housing. A first battery is located in the housing, the first battery using a first cell technology. A second battery is located in the housing, the second battery using a second cell technology that is different from the first cell technology. The battery pack can be connected to a portable computer chassis to provide an extended life power source. Each battery is coupled to an independent battery management unit (BMU). Each BMU shares a common connector.
