I have done it, but it is still not detected. The only way to be able to monitor the battery is to read the "/proc/pmu/battery_0" file. So I am writing a simple script to display the battery percentage based on the contents of that file.
You are using a battery plugin, like xfce4-battery-plugin, right?
In any case, we can append this script to the battery sector as a fallback.
Good luck.
