After running in battery mode for about 5h the system shut down without warning. First time while surfing the net and afterwards while restarting the system. Remaining battery life reported: 1:36h. So the problem still occurs.
Attached is the output of running "dmesg | grep ACPI". I don't know what these errors mean reported there or what to do about it. Maybe someone at Ubuntu will send this to someone having a clue.
