please attach the output of "grep . /proc/acpi/thermal_zone/*/*".
And there are several problems of the ACPI thermal control on your laptop,
1. > Critical temperature reached (72 C), shutting down.
the critical trip point on your laptop is 72C, which is quite low...
2. the ACPI thermal active cooling doesn't work because it uses a fake ACPI
fan.
3. the ACPI thermal passive cooling doesn't help a lot well because the
processor frequency change is not available.
so my questions is, can you hear the fan spinning when the computer goes hot?
is the computer really hot when it shutdown?
