These tell you a few things, but they're not thermal alarms. Event 0x6040 means it is unplugged from the AC. Thermal table changes are a hint to userspace to change power profile, which the Lenovo Windows driver uses for something unknown to me. The "undocked from hotplug port replicator" is self-explanatory. And the fact that it overheats means something REALLY isn't right, but it is very unlikely to be related to thinkpad-acpi :-( Possibly, something gets stuck when you undock and starts wasting power like crazy (e.g. by hogging the CPU). -- "One disk to rule them all, One disk to find them.
