I think the feature described above was introduced even before, but in kernel 5.13, that does not seem to work: no matter what you write in that file, the change will not be persisted. However, if you put the laptop to sleep, the value in the file will not change.Ībove I said that you need kernel 5.15. Note that this also holds if you hibernate (suspend to disk) the laptop since when you restart it from hibernate, you’ll boot it anyway, so that will reset the value in the file. If you reboot, the value in that file will go back to ‘100’, and charging will effectively continue. This value is reset to 100 when the kernel boots. Note that in the quotation shown above, you also read That notice will stay like that, as shown in these two screenshots (KDE Plasma), taken at different times: ![]() The DE might even tell you that it still needs some time until fully charged, but you can ignore that. Depending on the DE, either you see the charging notice disappear, or the charging stuck at 80%. However, associated file ( /sys/class/power_supply/BAT*/charge_full ) is read-only as (related to x86 PC arches) it is likely to be the copy of some EEPROM hardcoded value.Echo '80' | sudo tee / sys / devices / platform / lg - laptop / battery_care_limitĪfter that, you can see that when charging reaches 80%, the laptop will not charge the battery anymore. POWER_SUPPLY_CHARGE_FULL : This would indeed be interesting to change when the BIOS / OS get it all wrong after changing for new batteries. POWER_SUPPLY_CHARGE_NOW : Which is related to the instantaneous battery capacity and which obviously cannot be modified because irrespective of read-only files permissions, that value is almost certainly updated regularly by whatever BIOS / OS program. In which you could realise that there is no such a thing known as " default battery capacity"Īt least two data could appear related to you search : You should anyhow first have a look to the documentation regarding the Linux Power Supply Class. So just browse into that directory or use possibly more convenient cli tools such as upower or acpi. In Linux, everything related to batteries can be found under the /sys/class/power_supply directory tree. ![]()
