[EMAIL PROTECTED]:~$ dmesg|grep battery
ACPI: Battery Slot [C1ED] (battery present)
ACPI: Battery Slot [C1EC] (battery absent)
It should be clear, that kpowersave (or some backend which it uses) calculates
this informations wrong, but I think the new way (if it's not a bug) to show
each potential battery, unless it's connected or not (and I think I don't have
an second battery slot ;)) is wrong.
It's confusing for me, too, that in /proc/acpi/battery are C1EC and C1ED
reoported and in /sys/class/power_supply/ C1EB and C1ED. This seems wrong for
me.
Unless I think the following git commit from 2.6.24 could cause this problem
for me: 508df92d1f8d1921013cb4f45bb547d0eaff912a
Because it should prevent such situations which I never had got but now.
