NAME

6       powertop - a power consumption and power management diagnosis tool.
7

SYNOPSIS

9       powertop [options]
10

DESCRIPTION

12       powertop  is a program that helps to diagnose various issues with power
13       consumption and power management.  It  also  has  an  interactive  mode
14       allowing  one  to  experiment  with  various power management settings.
15       When invoking powertop without arguments powertop starts in interactive
16       mode.
17

OPTIONS

19       --auto-tune
20              Set  all  tunable options to their good setting without interac‐
21              tion.
22
23       -c, --calibrate
24              Runs powertop in calibration mode.   When  running  on  battery,
25              powertop can track power consumption as well as system activity.
26              When there are enough measurements, powertop can start to report
27              power  estimates.   One can get more accurate estimates by using
28              this option to enable a  calibration  cycle.   This  will  cycle
29              through  various  display  levels  and USB device activities and
30              workloads.
31
32       -C, --csv[=filename]
33              Generate a CSV report.  If a filename is not specified then  the
34              default  name  powertop.csv is used.  The CSV report can be used
35              for reporting and data analysis.
36
37       --debug
38              Run in debug mode.
39
40       --extech=devnode
41              Use the Extech Power Analyzer for measurements.  This allows one
42              to  specify  the serial device node of the serial to USB adaptor
43              connecting  to  the   Extech   Power   Analyzer,   for   example
44              /dev/ttyUSB0.
45
46       -r, --html[=filename]
47              Generate  an  HTML  report.  If a filename is not specified then
48              the default name powertop.html is used.  The HTML report can  be
49              sent to others to help diagnose power issues.
50
51       -i, --iteration[=iterations]
52              Number of times to run each test.
53
54       -q, --quiet
55              Suppress stderr output.
56
57       -t, --time[=seconds]
58              Generate a report for a specified number of seconds.
59
60       -w, --workload[=workload]
61              Execute  workload  file as a part of calibration before making a
62              report.
63
64       -V, --version
65              Print version information and exit.
66
67       -h, --help
68              Show the help message and exit.
