My Lenovo thinkpad T440s has the next product number:
$ cat /sys/class/dmi/id/product_name 20ARS0LF0A
So all the procedures show here are valid for this product
Fist and if you don’t install thinkfan, lm_sensors and hdapsd before:
$ sudo dnf install thinkfan hdapsd lm_sensors $ sudo sensors-detect $ sudo sh -c "find /sys/devices -type f -name 'temp*_input' | xargs -I {} echo "hwmon {}" >> /etc/thinkfan.conf" $ sudo systemctl enable thinkfan
The next step is install tlp and prepare other tools for manage kernel modules:
sudo dnf install tlp tlp-rdw kernel-devel akmods kmodtool
We need to enable external repositories:
$ sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm $ sudo dnf install http://repo.linrunner.de/fedora/tlp/repos/releases/tlp-release-1.0-0.noarch.rpm
Now this is the last part of the installation, but read carefully this warning:
The next instructions are no recommended, we use the --nogpgcheck
, so we not only use a external repository, we don’t check the sing the packages.
If you are comfortable with this just:
sudo dnf install akmod-tp_smapi akmod-acpi_call --enablerepo tlp-updates-testing --nogpgcheck
The --enablerepo tlp-updates-testing
is necessary for fedora 25+ versions.
Now you can have a very well use and administration of your batteries 🙂
Many thanks to linrunner and the TLP project.
I think you are missing a proper thinkfan configuration: does the output of
thinkfan -n
really show a working configuration? I would expect that you need to add sensors to /etc/thinkfan.conf
That is right, fixed and thanks. 🙂
