Abstract:
1. An information handling system comprising: plural electronic components operable to cooperate to process information, the electronic components consuming direct current power at one or more destination voltages; a power supply interfaced with the plural electronic components and operable to accept direct current at a source voltage and supply the direct current to the electronic components at one or more destination voltages associated with the electronic components; a power adapter operable to accept alternating current from an external power source and convert the alternating current to a first or second constant source voltage for use by the power supply, wherein the second constant source voltage is greater than the first constant source voltage; and a power manager interfaced with the power supply and the power adapter, the power manager operable to monitor a power consumption level of the electronic components and to command the first constant source voltage for a first power consumption level and the second constant source voltage for a second power consumption level at a predetermined power consumption threshold, wherein the second power consumption level is greater than the first power consumption level and wherein increasing from the first constant source voltage to the second constant source voltage decreases current provided by the power adapter.
