Thinkwatt is a bash script for use with thinkpad laptops.
However, as of v0.2, it works with all kinds of laptops as long as they've got a battery attached.
Thinkwatt can
- record your power consumption,
- calculate an average of that consumption
- and visualize that data in a 2D gnuplot graphic.
usage: thinkwatt -r <seconds> [-o <file>] [-f] [-q]
thinkwatt <-p | -a> <file> [-q]
options:
-r, --record record power consumption and optionally create a graph from the gathered data
-p, --plot create a plot image from one or two specified data files
-a, --average calculate the average power consumption from a specified data file
-q, --quiet makes thinkwatt less chatty
-o, --output the output file. can be prepended by a path.
-f, --force ignores the AC status. output may be useless, as power draw is zero until plugged out (avg is reduced as well)
-h, --help show this help text
examples:
thinkwatt -r -f (will record to a temp file until cancelled, you may record the very events happening at AC removal)
thinkwatt -r 300 -o /foo/bar/consumption.dat (will record for 5 minutes to the specified file)
thinkwatt -p /foo/bar/consumption_bat0.dat /foo/bar/consumption_bat1.dat (will create a graph from the specified files)
Thinkwatt works with all laptops, not just Thinkpads.
If you're running thinkwatt on a Thinkpad it is still recommended to use tp_smapi as it provides more accurate results than the generic acpi.
