Zenbook UX431 battery

See https://github.com/linrunner/TLP/issues/321#issuecomment-587184825 for context..

I have been also checking the source code to see if changes have been added for the past couple of weeks :)

Here..
https://github.com/torvalds/linux/blob/master/drivers/platform/x86/asus-wmi.c

@klausenbusk are you here?
Is there any news about this? or can't you do it now?
May be this thread have been missed by you for lost time or Idk.

Hi @userofryzen. I haven't got time to look at it and I don't like just adding every "battery name" (it is a "temporary" solution, we need a permanent solution).

okey, have you something on mind?
I think a recursive function that looks in every BAT x being x letters and numbers?
I don't know if it's efficient or not etc.. I hope someone can solves it

Someone beat me to it: torvalds/linux@9a33e37

Glad to hear it's implemented finally :)

It's going to become a loooong list if they keep those batterynames coming..

Hi,

for a proper implementation in TLP i need answers to the following questions:

1. What are the valid values / the range for charge_control_end_threshold?
2. May i assume that the threshold works exactly the same way – values, range, charge behaviour – for all ASUS laptops that expose /sys/class/power_supply/BAT0/charge_control_end_threshold?
   2a. If not, how do I distinguish the variants e.g. in /sys/class/dmi/id/*
3. How do i check that asus_wmi is loaded – does /sys/module/asus_wmi exist?
4. Is the battery always named BATx or else?

Hi

for a proper implementation in TLP i need answers to the following questions:

Is there any issue I can track?

What are the valid values / the range for charge_control_end_threshold?

0-100, but there is one report of it only supporting 60, 80 and 100.

May i assume that the threshold works exactly the same way – values, range, charge behaviour – for all ASUS laptops that expose /sys/class/power_supply/BAT0/charge_control_end_threshold?

I don't know, but probably (if you ignore that one report).

How do i check that asus_wmi is loaded – does /sys/module/asus_wmi exist?

/sys/module/asus_wmi does indeed exists.

Is the battery always named BATx or else?

The code is currently hard-coded to only create charge_control_end_threshold if the battery name is BAT0, BAT1 or BATT.

Is there any issue I can track?

Well, yes ... here you are. I added another question there.

The wait is over: the stop charge threshold is implemented for TLP 1.4.

Please participate in the alpha test. All necessary information is here.

Have fun.

Asus UX3404VA supports only 60, 80, and 100 in the /sys/class/power_supply/BAT0/charge_control_end_threshold file (as reported above).

Does anyone know that this is a hardware or software limitation? Do you have any workarounds to bypass it?
