powertop
A Linux tool for diagnosing power consumption issues and optimizing power management settings.
What is powertop?
PowerTOP is a Linux tool designed to diagnose and optimize power consumption on Linux-based systems. It analyzes which hardware components, kernel drivers, and applications are using the most power, and provides an interactive mode to tweak power management settings for improved energy efficiency.
Linux system administrators, developers, and power users who want to extend battery life on laptops, reduce energy usage on servers, or troubleshoot power-related performance issues.
PowerTOP offers deep, system-level visibility into power usage that standard monitoring tools lack, combined with actionable tuning capabilities to implement power-saving settings not enabled by default in many Linux distributions.
