apport information ** Description changed:
I've found this happening an increasing amount since upgrading to 12.04. When under heavy load my laptop has all fans at full speed but still often reachs critical heat (on the hard drive I think) and shuts itself off. I think this is mostly poor hardware design but it would be awesome if linux was able to detect dangerous temperatures, and if fans are already on full, scale CPU and GPU operations down to reduce heat so that a fatal shut-off can be avoided. I have an HP Pavilion with Intel core i7 and ATI Radeon HD 5000. + + I've installed indicator-cpufreq so I can manually control CPU frequency + when at high load. This seems to effectively reduce the temperature but + it would be good if the system could do this automatically. ** Tags added: apport-collected precise staging ** Description changed: I've found this happening an increasing amount since upgrading to 12.04.
