7 About PowerTOP
PowerTOP can be used to analyze CPU and power usage on a system, and provide suggestions for power management improvements. The statistics that PowerTOP provides include CPU usage and wakeup calls for each process, kernel worker, and device in the system.
PowerTOP can be started in interactive mode by running sudo powertop
without passing any options to the command. In interactive mode, PowerTOP displays the
data in real time in a tabbed interface and lets you make nonpersistent changes to
various power settings for testing purposes. The tabbed interface contains a
Tunables tab that lists recommendations on power-tuning
settings.
Use the powertop command with the --csv and
--html options to generate CSV and HTML reports for reporting and
data analysis.
For more information, see the powertop(8) manual page.

new profile configuration file with the PowerTOP recommendations commented out so
that you can review and decide which ones to include in the new profile.
