Hi,
i have written a patch with which the battery-module can run an command
on alarm.
E.g when the battery drops under 10 min remaining time then you
can initiate the shutdown of the system.
the command is currently executet via the system-fn call. If it is
there a better methode to do it then let me know it.
Regards
Stephan Wezel
