Classification: CPC G  H | IPC G  H

Claim 0:
1. An information handling system comprising:
a housing having first and second housing portions rotationally coupled by a hinge;
a display sized to couple over the second housing portion;
a main board coupled to the second housing portion under the display, the main board having a central processing unit and memory that cooperate to process information and that interfaces with the display to present the information as visual images at the display, the central processing unit operating at a system voltage;
a secondary board coupled to the first housing portion, the secondary board having an embedded controller to manage operating conditions in the housing;
a battery coupled to the first housing portion and having a native voltage having a greatest value at a full charge of the battery equal to a battery full charge voltage and having a decreased value as the battery discharges, the battery interfaced with the secondary board to communicate power to the secondary board at the native voltage; and
a battery cable connected to the main board and the secondary board, the battery cable communicating power from the secondary board to the main board at the battery native voltage, the main board reducing 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.
