A system of one embodiment is disclosed that includes a load, a power supply, and a mechanism. The load is operable in a default mode and an alternate mode. The load has better performance in the default mode than in the alternate mode, and consumes less peak power in the alternate mode than in the default mode. The power supply is connectable to an external power source to provide voltage to at least the load. The mechanism causes the load to operate in the alternate mode upon detecting the voltage provided by the power supply dropping below a predetermined threshold level than a predetermined threshold number of times.
