First of all: sorry for the last mail. I copy pasted the wrong email. Needed to resend it as I sent it with the wrong mail account to the list. @Curtis: Thanks. The hint to the manpage and the "last_full_capacity" property did their job. On 16.08.2014 22:11, Jakub Klinkovský wrote: > On 15.08.14 at 12:27, Chrisitan Burkard wrote: >> ...

I can confirm this behaviour but with different thresholds. Because of the age of the battery a FULL is never reached. The battery just has to get really low in order to come to its charging status. I just remembered a thing and would be interested what you think. Today only arch runs on my notebook but some time ago I was using dualboot windows, too. At that time the lenovo energy manager realized I mainly use the notebook on AC and switched the maximum battery capacity to around 70% (cannot recall the ecact value). I did not switch that back to 100% before wiping windows. -Is it possible that's (partially) the reason for the low CHARGE_FULL value compared to the CHARGE_FULL_DESIGN value? Or to put it different: Is it possible that the lenovos' windows energy manager driver set CHARGE_FULL to a lower value and linux drivers cannot overwrite this value? -Is there a possibility to change propertys displayed in /sys/class/power_supply/BAT0 without reinstalling windows and fixing it there? If you have links or knowledge for me, I would be really glad as I didn't find anything on my own. Best regards, Christian
