Battery cycle count on thinkpad x230

Hi everyone!

Since tp_smapi doesn't work on new thinkpads anymore, i'd like to know if there is another way to display the battery cycle count on newer thinkpads. Did someone find a solution?

Re: Battery cycle count on thinkpad x230

The functionality of tp_smapi has partly been replaced by the acpi_call kernel module. You can use it to set charge thresholds, but i do not know if it supports reading the cycle count. Maybe researching acpi_call can help you.

EDIT:
YES, you can read the cycle count on newer thinkpads. The script 'tlp stat' shows it. You can find tlp on aur:

Thanks for the hint, but unfortunately tlp-stat show as cycle count just "0", which is definitely wrong. Lets hope it will be fixed in the future

Re: Battery cycle count on thinkpad x230

I think this is because tlp probably just gets the cycle count from /sys/class/power_supply/BAT*/cycle_count, for which mine too reads 0.  I have a Thinkpad Edge E430, and tp_smapi does not work for my machine either.  I am curious to know the result if you end up trying the acpi_call kernel module though (also suggested by teateawhy), as that is something I am just hearing about now.

Hi,

unfortunately there is currently no way to read the battery cycle count for the ThinkPad *30 series within Linux. If you learn of one, please tell me ;-).
