I can confirm this with my Thinkpad z60m using an ultrabay advanced battery as the second one.
If both battries are inserted during startup gnome-power-manager detects both and details are shown in the info dialog. If the ultrabay battery runs out of power gnome-power-manger happily suspends my thinkpad ignoring the main battery. If I insert the second battery while gnome-power-manager is running it will not be detected. -- Dual / Two Batteries, shutdown on empty expansion battery. (GPM only recognises first battery) https://launchpad.net/bugs/60442 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
