Jean I know that I have a EMC1402 chip because this is what the "sensors-detect" command report: Driver `to-be-written': * Bus `SMBus PIIX4 adapter at 0b00' Busdriver `i2c_piix4', I2C address 0x4c Chip `SMSC EMC1402' (confidence: 6) Driver `adm1021': * Bus `SMBus PIIX4 adapter at 0b00' Busdriver `i2c_piix4', I2C address 0x4e Chip `Maxim MAX1617' (confidence: 3) Driver `k10temp' (autoloaded): * Chip `AMD Family 11h thermal sensors' (confidence: 9) Note: there is no driver for SMSC EMC1402 yet. I searched around but I haven't found a specific vendor's driver for my laptop (HP 6735s) and ACPI has a strange behavior: rarelly, when I turn on my laptop, the fan works, but 90% it doesn't start except when temp is around 85 celsius. I have already tried all boot options (acpi=force, acpi=off, acpi=osi_Linux, acpi_enforce_resources=lax) but without succes.

Can you use that ? On laptops it is almost never possible to access monitoring chips directly, one has to go through ACPI or a vendor-specific layer. So Kenny should prepare himself to the idea that the emc1403 driver in linux-next will most likely not work. But it's certainly worth a try anyway. Kenny, how do you know that your laptop has an EMC1402 chip? Doesn't the ACPI thermal driver work for you? Did you try the vendor-specific driver for your laptop? Some of them (asus-wmi, compal-laptop, eeepc-laptop and thinkpad_acpi) provide temperature readings. -- Jean Delvare SUSE L3 Support _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
