SYNOPSIS

powertop [ options ]

DESCRIPTION

powertop is a program that helps to diagnose various issues with power consumption and power management. It also has an interactive mode allowing one to experiment with various power management settings. When invoking powertop without arguments powertop starts in interactive mode.

OPTIONS

--calibrate

runs powertop in calibration mode. When running on battery, powertop can track power consumption as well as system activity. When there are enough measurements, powertop can start to report power estimates. One can get more accurate estimates by using this option to enable a calibration cycle. This will cycle through various display levels and USB device activities and workloads.

--debug
