Abstract:
1. An information handling system comprising: plural components that consume power to process information, the plural components including at least a central processor unit; a battery that charges to store power and discharges the stored power to provide power to the plural components; a power subsystem operable to provide direct current voltage to the plural components; a power adapter operable to convert alternating current to direct current and to provide the direct current to the power subsystem; an adapter manager integrated with the adapter and operable to adjust the adapter direct current voltage output between a first voltage level and a second voltage level; and a power manager associated with the power subsystem and interfaced with the adapter manager, the power manager operable to issue a general purpose input/output (GPIO) state to command the first direct current voltage if the central processor unit has a first power consumption state in which the central processor unit consumes a first amount of power and the second direct current voltage if the central processor unit has a second power consumption state in which the central processor unit consumes a second amount of power, wherein at least some of the plural components consume power in both the first and second power consumption states.
