Classification: CPC G  H | IPC G  H

Claim 9:
10. A method for managing power of an information handling system, the method comprising:
coupling a battery to a housing first portion, the battery having a native voltage, the native voltage equal to a full charge voltage of the battery when the battery is fully charged, the native voltage decreasing as the battery discharges to have less than the full charge voltage;
coupling a secondary board to the housing first portion;
interfacing the battery and secondary board to provide power to the secondary board at the native voltage;
coupling a main board to a housing second portion, the main board having a central processing unit and memory, the central processing unit operating at a system voltage, the housing second portion rotationally coupled to the housing first portion by a hinge;
interfacing the secondary board and the main board by a cable;
communicating power from the battery through the secondary board at the native voltage and then to the main board through the cable at the battery native voltage; and
reducing the native voltage at the main board from the native voltage by at least a factor of five to the system voltage;
wherein the main board reduces the native voltage by numerical factors that are based on battery native voltage level changes over time.
