ACPI battery state doesn't get updated
Dear list,
after installing Debian on an old IBM Thinkpad
everything seems to be working fine, except that
the battery state is constant, i.e. it is read
once correctly at bootup and doesn't change
afterwards. On the other hand, the ACPI system does
recognise when I plug/unplug the AC (which sets
/proc/acpi/ac_adapter/AC/state to off-line, but
does not change /proc/acpi/battery/BAT1/state from
charging to discharging).
Is this a problem with the BIOS, or is there a
possibility to set a polling interval for the
battery, similar to the one found at
/proc/acpi/thermal_zone/THRM/polling_frequency, that
just has a ridiculously high default setting?
Here is a copy of the ACPI lines of dmesg (if it
is of help, I can attach the complete syslog/dmesg);
all ACPI stuff is compiled into the kernel, so no
module loading:

I'd be very glad if someone can help me.
Thanks in advance!
