New cinnamon install: fix battery indicator for lenovo laptop

Difficulty: ★★☆☆☆

When installing Manjaro Cinnamon, the battery can be stuck at 10% or not changing.

  1. check your tlp settings:

    sudo tlp-stat --battery

    which indicated:

    Install acpi_call kernel module for ThinkPad battery recalibration

  2. If that’s the case, install acpi_call. As there are several versions, the below tutorial uses dkms so it’s available for all of your kernels.

    pamac install acpi_call-dkms
  3. change your mkinitcpio.conf file to include MODULES=(battery):

    sudo nano --backup /etc/mkinitcpio.conf
    • Press Ctrl+W
    • Type MODULES= and hit Enter
    • to find the line starting with MODULES
      • If that line starts with #, please remove the hash character
      • If not, ensure that line contains (battery).
  4. reinitialize your initial RAM disk environment:

    sudo mkinitcpio --allpresets
  1. Reboot:

    sudo reboot
