No problem, I'm at least as slow with e-mail, and I don't even have any
excuse ;-)

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).

Indeed, I had no battery inserted. 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).

I have 2 when it's charging, and 1 when it's discharging.

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,
