Swift X - SFX14-41G #10

Closed freddy8051 closed 1 year ago

freddy8051 commented 1 year ago

I have a Swift X - SFX14-41G and I can confirm that the health mode works and it stops charging at 80%.

I've noticed that if I plug the charger in if the battery is >80% it doesn't stop charging to let the battery drop back to 80%. It stays at the battery level it was when it was plugged in. I am planning to test the calibration mode so I will report back.

acer_wmi: Unknown function number - 8 - 0 #unplugged acer_wmi: Unknown function number - 8 - 1 #plugged in This appeared in dmesg after activating health mode. I'm unsure if this is relevant to your driver or if it is an acer specific thing. I haven't noticed any issues and the driver appears to work as expected. Thanks so much.

Hey, @freddy8051 First of all, thank you for testing on Swift X - SFX14-41G! I am using Fedora 37 and having the same model.

I am just curious,

  1. What distro and kernel do you use?
  2. What is the experience by so far?
  3. @frederik-h With the future kernel updates, will it be an issue if the native module will be added to the kernel supporting acer wmi batteries natively?

Thanks!

@art-tapin I use EndeavourOS and I'm using the 6.1.1-AMD kernel mainly because of the AMD p-state drivers being included prior it being mainlined and I haven't bothered checking if others work. I can try testing it on another kernel if needed.

the unknown function 8-0 and 8-1 appears in dmesg when the charger is plugged in our unplugged (usb c or the barrel charger), but I imagine it's because of health mode. Outside of that I haven't noticed anything abnormal any my laptop has been functioning as expected.

@freddy8051 thank you so much! Have you tried the similar module that was developed by maxco2

Could you please try the module on Fedora 37 Workstation 6.1 stock kernel?

Thank you again!

I'm not a fedora user, but maybe you can try it and let us know :)

One thing i found is if I let my battery run out it doesn't save health mode unless the module is loaded during boot. i think this might be an acer limitation but it's an easy fix to have the module load. so far everything has worked great.
