Bug Description
In the last 10 minutes, I've twice had the machine shutdown by itself.
My hunch is corrupt ACPI data leading to a zero-juice situation (both batteries are full charged *and* external power are available), combined with the lack of being able to pick a "Doing Nothing" option in GNOME Power Manager as a work around.

I had a shutdown again today; this one was a temperature threshold going critical:
$ grep -A1 'shut.*down' /var/log/syslog
Oct 6 10:43:47 localhost kernel: [26394.422223] Critical temperature reached (128 C), shutting down.
Oct 6 10:43:47 localhost kernel: Kernel logging (proc) stopped.
Post reboot, temperatures of 73°C are showing:
$ grep -r . /sys/devices/ virtual/ hwmon/hwmon* /temp* devices/ virtual/ hwmon/hwmon0/ temp1_crit: 127000 devices/ virtual/ hwmon/hwmon0/ temp1_input: 73000 devices/ virtual/ hwmon/hwmon0/ temp2_crit: 100000 devices/ virtual/ hwmon/hwmon0/ temp2_input: 73000

Seems looking back at the log files from yesterday that the same probably happened.
