Setting the Minimum Processor Idle Power Package C-State

Use the Minimum Processor Idle Power Package C-State option to configure the lowest processor idle power state (C-State). The processor automatically transitions into package C-States based on the C-States in which cores on the processor have transitioned. The higher the package C-State, the lower the power usage of that idle package state.
