This is REALLY REALLY REALLY cool. No, I mean literally, this laptop, a Satellite 2805-S201, is now cool. By forcing the fan on, I've lowered the temperature by more than 12K. That makes it cool enough that my leg doesn't think its on a spit above a barbeque pit. Before forcing the fan on: hw.acpi.thermal.tz0.temperature: 3282 After forcing the fan on it seems to have stablized around: hw.acpi.thermal.tz0.temperature: 3162 ./acpi_temp System temperature = 316.2 K 43.0 C 109.4 It was 315.2K before I started Opera. 5 minutes later: ./acpi_temp System temperature = 311.2 K 38.0 C 100.4 F I've also set the LCD brightness to 0. It's not a dramatic effect but it *is* somewhat less bright than it is at 7. Thank you for doing this Mr. Garcia. Mr. Lawson, is it possible this patch could find it's way into the base tree someday? -- Scott Lambert KC5MLE Unix SysAdmin lambert@lambertfam.org
