Abstract

An information handling system is described having a power supply (16) having a switching circuit (24) that switches a plurality of energy sources (20) and (22) between series and parallel couplings. Associated with the switching circuit (24) is a voltage level detecting circuit (18) for monitoring the voltage level of the energy sources (20) and (22). A processor (12) for controlling the information handling system (10) responds to the voltage level detecting circuit (18) and in the event of a low voltage condition, the processor (12) activates the switching circuit (24) to switch the energy sources (20) and (22) from a series to a parallel coupling. Alternatively, processor (12) responds to other inputs or conditions for actuating switching circuit (24).
