Hello everyone I have an ACER Aspire A315-42, I really wanted to limit the battery because it is constantly on charge Acted according to the instructions

sudo apt install build-essential linux-headers-$(uname -r) git
git clone https://github.com/frederik-h/acer-wmi-battery.git
cd acer-wmi-battery
make
sudo insmod acer-wmi-battery.ko

echo 1 | sudo tee /sys/bus/wmi/drivers/acer-wmi-battery/health_mode

There is no reaction, the command just freezes, there is no error

I also tried sudo insmod acer-wmi-battery.ko enable_health_mode=1 It shows no errors and the command passes, but the limit is not included

Per team 

cat /sys/bus/wmi/drivers/acer-wmi-battery/health_mode
-1

bios of the latest version, am I doing something wrong or does my laptop have no support?

It seems that the laptop is not supported (cf. e.g. this thread on the acer forum. However, I don't think that the write should freeze in this case. Could you take a look at the kernel output with dmesg?

See also issue #23 which reports that another Aspire 315 model is not supported.
