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 con-
     sumption  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, power-
	    top 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 dis-
	    play levels and USB device activities and workloads.

     -C, --csv[=filename]
	    Generate a CSV report.  If a filename is not specified then the  de-
	    fault name powertop.csv is used.  The CSV report can be used for re-
	    porting 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 connect-
	    ing 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  re-
	    port.

     -V, --version
	    Print version information and exit.

     -h, --help
	    Show the help message and exit.

COMMANDS
     In interactive mode, the following key bindings are available:

	    tab(@);  l l.  Tab@Show next tab BackTab@Show previous tab Right Ar-
