Method and apparatus allowing a battery to regain charge in a handheld device without an applied external charge while still supplying power selected designated components

摘要

An embodiment includes a power management method for regulating power to a handheld computer. A source voltage is received from a battery module. The source voltage is regulated to power a plurality of internal components, including a processor and a memory. If the source voltage is detected to be less than a designated threshold, the plurality of internal components powered by the source voltage are reduced to allow a charge of the battery module to increase in absence of an external charge.
