ACPI and cpufreq are areas in which many developments have been done in the past months. Maybe this would fix the problems you observe altogether. > Next adapter: SiS96x SMBus adapter at 0x1000 (Algorithm unavailable) > Do you want to scan it? (YES/no/selectively): Surpisingly, nothing is found on the SMBus, this is quite rare not to even see an EEPROM or a clock chip here. Can you please provide the output of "i2cdetect 0"? It is probable that you actually have nothing here, but that could also be an SMBus driver issue. > Probing for `Nat. Semi. PC87351 Super IO Fan Sensors' > Failed! (0xea) So you have a Super-I/O chip, most probably from National Semiconductor. Do you happen to know what it is? Our script doesn't seem to know. Sometimes Super-I/O chips include hardware monitoring capabilities. Are you certain that your laptop does support hardware monitoring ? It's quite frequent that they don't. You may take a chance with ACPI (look at /proc/acpi/thermal_zone and /proc/acpi/fan). This is rather limited compared to what lm_sensors offers, but better than nothing, and quite often that's the best you can get on laptops. -- Jean Delvare
