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,  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.

       --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.
