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
              Show the help message and exit.
