Charge_control thresholds not found

Describe the bug
Hi, I have installed Ubuntu 18.04 on my Matebook 13. I followed your instructions and installed the v3.2 driver. However, after installation I cannot find the "sys/class/power_supply/BAT0/charge_control_{start,end}_threshold or /sys/devices/platform/huawei-wmi/charge_control_thresholds" files for controlling the thresholds. I tried then to upgrade to Ubuntu 19.10 to use the v3.4 driver, but I still cant find the files. I performed the installation using dkms tarball. Could you help me out?

Desktop (please complete the following information):

  • Kernel [5.3]
  • Distro [Ubuntu 19.10] `
  • Loaded WMI modules lsmod | grep wmi
    snd_rawmidi 36864 1 snd_seq_midi
    snd_seq_device 16384 3 snd_seq,snd_seq_midi,snd_rawmidi
    mxm_wmi 16384 1 nouveau
    wmi_bmof 16384 0
    intel_wmi_thunderbolt 20480 0

Maybe I did not understand your installation instructions properly, could you help me out? Thanks.

I saw there was a previous issue similar that was similar to mine, and it was solved by rebooting. However, I have also tried that but it doesnt seem to solve my problem

I tried to build it from source using your instructions:
git clone https://github.com/aymanbagabas/Huawei-WMI
cd Huawei-WMI
make

To update use:

sudo cp huawei-wmi.ko /lib/modules/$(uname -r)/updates/
sudo depmod

To install use:

sudo make install

When I ran sudo make install, this is the error message that returned:
make -C /lib/modules/5.3.0-24-generic/build/ M=/home/rusern/Huawei-WMI modules_install

What's the output of lsmod | grep wmi now that you've installed the driver manually and rebooted?

The driver is clearly not loaded. Closing.
