Often the processor only works with a partial load. In this case, it can be run with a lower frequency. Usually, dynamic frequency scaling controlled by the kernel on-demand governor is the best approach.

Throttling should be used as the last resort, for example, to extend the battery operation time despite a high system load. However, some systems do not run Advanced Configuration ACPI when they are throttled too much.

What is ACPI (Advanced Configuration and Power Interface)? - Definition from

For in-depth information, refer to Section On one hand, the ACPI code of the kernel may contain bugs that were not detected in time. ACPI is in Advanced Configuration ACPI a response to global concerns about energy conservation and environmental control. Based on the collaborative effort of Hewlett-Packard, Intel, Microsoft, Phoenix, and Toshiba, ACPI moves away from power management that simply times out during inactivity to a more sophisticated demand-based power management.

ACPI components Advanced Configuration ACPI information about power consumption from the computer and gives that information to the operating system. The operating system then distributes power to the different computer components on an as-needed basis.

With ACPI, the computer can power itself down to a deep sleep state but still be capable of responding to an incoming phone call or a timed backup procedure. C0 is the operating state.

C1 often known as Halt is a state where the processor is not executing instructions, but can return to an executing state essentially instantaneously. All ACPI-conformant processors Advanced Configuration ACPI support this power state. This processor state is optional.

C3 often Advanced Configuration ACPI as Sleep is a state where the processor does not need to keep its cache coherentbut maintains other state. Additional states are defined by manufacturers for some processors. The idea behind these tables is to enable generic software to support standard intellectual property IP blocks that can be integrated into various platforms in diverse ways.

With the table strategy, the platform-variable attributes of a particular platform are provided in a table, and used by generic software to adapt itself to the specific set of IP blocks integrated into the platform. This software can therefore be written once, thoroughly tested, Advanced Configuration ACPI then optimized over time.

Specifically, this table contains pointers to the following: Indicates that ACPI hardware is not available Advanced Configuration ACPI this platform. Indicates that the platform supports low-power idle states within the ACPI S0 system power state that are Advanced Configuration ACPI energy efficient than any Sx sleep state. If this flag is set, Windows will not try to sleep and resume, but will instead use platform idle states and connected standby. This role influences power management policy for the display and input, and affects the display of on-screen keyboards.
