POWERTOP(8)			powertop manual			   POWERTOP(8)

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
       --calibrate
	      runs powertop in calibration mode. When running on battery, pow‐
	      ertop 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.

       --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.

       --help
	       show the help message.

       --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.

       --iteration[=iterations]
	      number of times to run each test.

       --quiet
	       supress stderr output.

       --time[=seconds]
	      generate a report for a specified number of seconds.

       --version
	      print version information and exit.
