The internal charging system can charge a battery that has a higher operating voltage than the voltage provided by the external power source. While charging the battery from the external power source, an internal charge controller can operate and inhibit functions of the device to indicate to user that a charging operation is commencing, and to prevent operation of the device when the battery voltage is too low to support such operation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for operating an internal charger system of a portable electronic device","description":"An internal charging system controls charging of a battery used to power an electronic device when an external power source is connected to the device.
