OK, as expected my laptop shut down when the second battery ran down and the first battery was still full. I'm attaching the gpm.log as requested.
The output from the new debugging statements in the patch is: [battery_status_changed_primary] gpm-manager.c:2058 (21:58:06): Laptop battery: critical level: [battery_status_changed_primary] gpm-manager.c:2059 (21:58:06): charging=0 discharging=1: [battery_status_changed_primary] gpm-manager.c:2060 (21:58:06): pct_charge=72 remaining=2: ** Attachment added: "gpm.log as second battery runs down" http://librarian.launchpad.net/4890173/gpm.log -- Dual / Two Batteries, shutdown on empty expansion battery.
