Claim:
A power control manager comprising: a calculator to determine power available in an electronic device based on a signal to be received regarding a maximum power available from a power source; a first storage area to store information for a plurality of device sub-systems; and a power credit distributor to receive a signal from the calculator regarding the determined power available from the power source, and the power credit distributor to determine one or more power levels for the sub-systems based on the available power received from the calculator and information stored in the first storage area, wherein: the information stored in the first storage area is to indicate power settings for a plurality of different combinations of the sub-systems when concurrently activated, and the power settings for one of the plurality of different combinations of the sub-systems are to include a power setting for a first sub-system and a reduced non-zero power setting for a second sub-system, and the reduced non-zero power setting is to be based on at least one derating value for the second sub-system stored in the first storage area, and the at least one derating value is a specific fractional percentage of a maximum power for the second sub-system to be used in operating the second sub-system for a specific setting.
