Patent ID: 7624287

Claim:
A method of operating a power-consuming device, comprising: selecting one of a plurality of predefined operating parameter sets, each of said operating parameter sets comprising a plurality of operating parameter values for said device defining a power consumption state, wherein said plurality of operating parameters values in each of said predefined operating parameter sets include adjustable operating parameter values and dependent operating parameters dependent on said adjustable operating parameter values; modifying to a new value at least one of said adjustable operating parameter values in said selected set that would prevent said device from meeting current operating demands to meet said current operating demands, wherein said new value of said adjustable operating parameter is taken from another operating parameter set of said plurality of predefined operating parameter sets; and modifying to a new value any dependent operating parameter dependent on said at least one of said adjustable operating parameter values in said selected set, said modifying resulting in a modified set of parameters; and applying said modified set of parameters to said device, to change said current power consumption state of said device.
