NAME

powertop - a power consumption and power management diagnosis tool. 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

--auto-tune

   Set all tunable options to their good setting without interaction.

-c, --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.

-C, --csv[=filename]

   Generate a CSV report. If a filename is not specified then the default name powertop.csv is used. The CSV report can be used for reporting and data analysis.

--debug

   Run in debug mode.

--extech=devnode

   Use the Extech Power Analyzer for measurements. This allows one to specify the serial device node of the serial to USB adaptor connecting to the Extech Power Analyzer, for example /dev/ttyUSB0.

-r, --html[=filename]

   Generate an HTML report. If a filename is not specified then the default name powertop.html is used. The HTML report can be sent to others to help diagnose power issues.

-i, --iteration[=iterations]

   Number of times to run each test.

-q, --quiet

   Suppress stderr output.

-t, --time[=seconds]

   Generate a report for a specified number of seconds.

-w, --workload[=workload]

   Execute workload file as a part of calibration before making a report.

-V, --version

   Print version information and exit.

-h, --help
