Abstract:
A handheld computer comprising:a rechargeable battery module to output a source voltage; a regulator coupled to the battery module to regulate the source voltage from the battery module; a plurality of internal components including a processor and a memory component that draw power from the source voltage; a power rail to extend power from the battery module to the plurality of internal components; and wherein in absence of an external charge to recharge the battery module, the regulator reduces a level of the source voltage to an operational level when the source voltage level is greater than a first threshold, and causes the source voltage to pass to the power rail without affecting the level of the source voltage when the source voltage level drops below the first threshold; wherein the level of the source voltage passed to the power rail when the source voltage drops below the first threshold is variable and decreasing; and wherein one or more of the plurality of internal components are, at least while the source voltage is below the first threshold and above a second threshold, functional using the source voltage that is passed to the power rail.
