Note

This has been tested on Linux 6.17 but may work on future versions.

1. Install the packages dkms, linux-headers, and unzip.

   sudo pacman -S dkms linux-headers unzip
   

2. Download the librem-ec-dkms project from librem-ec-dkms.

3. Move to the download location (typically ~/Downloads/) and extract the project.

   cd ~/Downloads/
   unzip ./librem-ec-acpi-dkms-master.zip
   

4. Copy the file dkms.conf from the debian/ directory to the root of the source directory.

   cp debian/librem-ec-acpi-dkms.dkms dkms.conf
   

5. Modify the dkms.conf file in a text editor so that PACKAGE_VERSION is set to a value.

   PACKAGE_NAME="librem_ec_acpi"
   PACKAGE_VERSION="1.0"
   BUILT_MODULE_NAME[0]="librem_ec_acpi"
   DEST_MODULE_LOCATION[0]="/updates/dkms"
   AUTOINSTALL="yes"
   

6. Add and build the module using dkms.

   sudo dkms add ./
   sudo dkms build librem_ec_acpi/1.0
   sudo dkms install librem_ec_acpi/1.0
   

7. Reboot your computer.

8. lsmod should show the librem_ec_acpi module.

   lsmod | grep librem_ec_acpi
   librem_ec_acpi         20480  0
   

9. You should also see new files to control the battery:

   • /sys/class/power_supply/BAT0/charge_control_start_threshold

   • /sys/class/power_supply/BAT0/charge_control_end_threshold

10. You can check the values with the commands:

    • cat /sys/class/power_supply/BAT0/charge_control_start_threshold
      40
      

    • cat /sys/class/power_supply/BAT0/charge_control_end_threshold
      95
