Should warn about the threshold feature can not be applied.

[corona10]

Some Lenovo laptop has the issue with setting the battery threshold.
https://access.redhat.com/discussions/6195601

It would be great if the user could notice that the battery threshold feature is not working.
By the way.., sigh situation, only conservation_mode works for my Fedora machine.. :(

[PurpleWazard]

Battery thresholds should work on your machine if you have the right acpi modules are installed. Also conservation mode will have higher priority than battery thresholds so turn off conservation mode and try again.

[shadeyg56]

It would seem that charge_stop_threshold is not available for them. You could try using tee instead of echo in the command you ran.

Also post auto-cpufreq --debug to give more info on your system

I already tried, they doesn't work, if it was set at BAT0, I think that it would work, but if the battery is configured at BAT1 there looks some issue.
Please read my original reference, the issue is perfectly the same: https://access.redhat.com/discussions/6195601

Please ignore the custom commit, I am using my own custom version #674
Except that, all implementations are the same.

[PurpleWazard]

to be honest i have no idea what would fix your issue the only things i can think of are:

you dont have to right acpi modules installed. could you send us the output of lsmod?

try booing off a live Debian on a usb stick and see if you have the correct acpi module running and see if the battery path is available.

can we also have your laptop model?

For Debian, I will try later :)

I ran into a similar issue today. The thresholds set in the config file were being ignored. Trying to echo or tee a value into charge_start_threshold and charge_stop_threshold yielded "permission denied" or "I/O error".

I managed to get the battery to charge by writing to charge_control_start_threshold and charge_control_stop_threshold instead, although this behaviour isn't super consistent, for example now I can write to the original threshold slots.

I suspect that the kernel or module were updated and something went slightly wrong. Also, I do not recall these *_control_* slots being there from when I was looking at them a couple of weeks ago when I got curious about how auto-cpufreq sets these thresholds. Maybe it's a new interface to use?

Although this issue isn't with auto-cpufreq, I second the request for an error message when setting thresholds fails. It's a fantastic tool BTW, thanks for your work!

For completeness, I have the required module:

from here charge_start_threshold is the legacy api from thinkpad_acpi and charge_control_start_threshold is the new api.

im currently working on adding warnings like what was suggested and then i will work on changing the api paths.

Amazing!

[corona10]

So you will work for

• charge_control_start_threshold
• charge_control_end_threshold

right?

[PurpleWazard]

yep it should.

[corona10]

Yeah but in my case, it will not work too :(

$> echo "90" | sudo tee /sys/class/power_supply/BAT1/charge_control_end_threshold

According to this documentaton, some products have issues.

[corona10]

but bat0 has the paths tho right?

My product has no bat0, so no way to check :)

[PurpleWazard]

igtg rn but ill check in the morrning

[PurpleWazard]

does your laptop support ideapad_acpi or ideapad_laptop kernal modules?
