Table 15. Direct Media Interface (DMI) States
State Description
L0 Full on – Active transfer state.
L0s First Active Power Management low-power state – Low exit latency.
L1 Lowest Active Power Management – Longer exit latency.
L3 Lowest power state (power-off) – Longest exit latency.

Processor Core Power Management
While executing code, Enhanced Intel SpeedStep
®
Technology optimizes the
processor’s frequency and core voltage based on workload. Each frequency and
voltage operating point is defined by ACPI as a P-state. When the processor is not
executing code, it is idle. A low-power idle state is defined by ACPI as a C-state. In
general, deeper power C-states have longer entry and exit latencies.
