Abstract
In a first embodiment, an information handling system (“IHS”) includes a processor. The IHS also includes a power rail coupled to the processor. The power rail supplies power, from a power adapter, to the processor. The IHS further includes a battery, that in response to a voltage fall on the power rail, supplies supplemental power to the power rail. In a second embodiment, an IHS includes a processor. The IHS also includes a power rail coupled to the processor. The power rail supplies power, from a power adapter, to the processor. The IHS further includes a battery, that in response to a voltage rise on the power rail, suppresses or sinks power supplied by the power adapter to the power rail.
