I recently bought a Sony VGN-N395E Laptop. I'm using Ubuntu Gutsy as the operating system. Laptop runs too hot (about 65-69C) and fan never kicks in. Spicctrl does not run correctly. All readings return 0 (zero). /proc/acpi/fan is empty. There is no fan control /proc/acpi/thermal_zone has two zones. temperature files always read 49-51 C no matter how hot laptop runs. I assume lmsensors show the correct reading. trip_points file show only passive cooling option and tripping point is set to 80C, way too high. I can't write to tripping_points, i get "bash: echo: write error: Invalid argument". I think this laptop has a different variant of the chip Mattia reverse engineered. This is a really big headache for me, can it be fixed? I can provide any information you want about the laptop. Here is the dmesg output => http://paste.ubuntu-nl.org/44159/ And dmidecode output => http://paste.ubuntu-nl.org/44160/ Please let me know if you need anything else. - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
