Hi, is this a not supported device?

having: acer travelmate p259-62-m manjaro 6.6

both sudo insmod acer-wmi-battery.ko enable_health_mode=1 sudo insmod acer-wmi-battery.ko

end up in: "insmod: ERROR: could not insert module acer-wmi-battery.ko: Input/output error"

sudo dmesg | tail -1

    "acer_wmi_battery: WMI battery status call returned a buffer of unexpected length 4"

Hello,

Did you try the charge limit function on windows? using the acer care centre? Not sure if it's supported in your laptop or not.

Here's an similar issue (https://github.com/maxco2/acer-battery-wmi/issues/1) . here you can run the sudo fwts wmi - command and see the outputs and match it to this pattern 79772EC5-04B1-4BFD-843C........ if it matches then you might have the function else most probably not.

also i hope you had installed the proper linux headers which is a pre-requirement for this.

Hi, thanks for the prompt response!

my SNID acer support does not offer 'acer care centre' only 'acer control centre'

Hey, sorry for the late reply got busy somewhere

If the acer control centre doesn't show that option that probably means that your hardware doesn't support this feature :(
