Well, i am not too much concerned about the heat. I just would like to understand how lenovo designed the thresholds because it does not make much sense. Also, i wonder what is the behaviour under windows, anyone could try? I mean, does windows control the heat and fan speed accordingly, or does it leave it to the bios (auto mode for the fan fed to the EC)? ___ ...... Original Message .......
