Platform Power Management

Listen to this glossary

Platform Power Management (PPM) refers to the various power management techniques and technologies that are used in a computer system to reduce power consumption and improve energy efficiency.

This can include features such as CPU Enhanced Halt (C1E), Intel Speed Shift Technology, and Advanced Configuration and Power Interface (ACPI) support. PPM can also include hardware and software controls for managing power consumption of other components such as memory, storage devices, and peripherals.

The goal of PPM is to reduce power consumption when the system is idle or under light loads, while still providing full performance when needed. This can help to extend battery life in portable devices and reduce energy costs in enterprise systems.
