Well, the battery state is unknown, so g-p-m can't really do anything
sensible here. I think part of the problem is that ACPI exposes two
values, is_charging and is_discharging, and so it's tricky to map them
to a sane number of states.
What's the value of state in the correct device in
/sys/class/power_supply? If this is fixed in the kernel, it'll just
work in g-p-m. Just lowering the threshold is not a good idea at all,
and I'll probably remove that hack from g-p-m altogether.
Richard.
