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: 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.

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.

Abstract: A method for reducing video display power usage by dithering the brightness. This method can be used to reduce power consumption without having an effect on the brightness of the display screen as perceived by the user or may further reduce the power consumed with a corresponding reduction of brightness.

Abstract: An information handling system includes a power management apparatus which is capable of selectively coupling to primary and secondary batteries that provide portable and backup power to the information handling system. The power management apparatus senses when the voltage at the power input of the information handling system drops below a predetermined threshold voltage. Respective switching diodes between the primary battery and the power input and the secondary battery and the power input are used as a means of fast hardware connection of the selected battery to the power input. Respective bypass switches are connected in parallel with the switching diodes. Control software instructs the bypass switch across the diode associated with the selected battery to close to prevent diode power loss. In this manner, a selected primary or secondary battery is independently switched to the power input, provided the selected battery exhibits a voltage greater than the predetermined threshold voltage.

Abstract: A computer system that is able to switch processor and bus frequencies, along with processor voltage, when the system is placed into AC from battery power mode, and when the system is placed into battery from AC power mode. The computer system includes transitioning a processor (CPU) into a low performance mode using a clock generator that provides different clock frequencies, a high performance clock frequency and a low performance clock frequency depending on whether battery or AC power is used. The processor and interconnecting busses use the lower clock frequency in order to save battery power.
