OK, I will try it with CURRENT as soon as I get the opportunity (I already have a thumb drive dedicated for that kind of tests). > > For the reference, in case it might help, here are some relevant sysctl: > > $ sysctl hw.acpi > > Let me compare; > > > hw.acpi.battery.life: -1 > > How did you get this value?

Years ago I took the habit of removing the battery of laptops used for long amount of time on AC (currently for my X220, that's 9h every workday), because keeping a fully charged battery on AC used to kill it. However I admit I don't know whether technology improved enough to mnake it a non-issue (or even whether even by then it was actually an issue and not an urban legend). Anyway, now with the battery inserted and charging, I still have hw.acpi.battery.life: -1. However, as soon as I unplug, I get a reasonable value there (currently 98, with hw.acpi.battery.time: 265). > > hw.acpi.battery.time: -1 > > hw.acpi.battery.state: 7 > > I have 0 here.

Interesting, though it turns out that not using it on my 9-STABLE does not help with any of the small issues I still have. Though I will try both with and without it when I experiment with CURRENT. Thanks for the point. Thanks for your help, Natacha Porté
