I can confirm this problem. I have an IBM Thinkpad a30p which has run hoary and dapper without issue. Once I upgraded to edgy the system will shutdown with no warning once one battery is empty.
Both batteries are new in the system and both have good capacity. If after the shutdown, I remove the empty battery, the machine is able to boot and run on the other battery and I get the normal notification as the power gets low. -- Dual / Two Batteries, shutdown on empty expansion battery. https://launchpad.net/bugs/60442 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
