(skipping family) You do have a primary Super-I/O chip, but we do not recognize it. If you have some technical documentation about your system, try finding out what Super-I/O chip this is. Some of these chips integrate hardware monitoring features, but not all. > So here comes MY QUESTION.

You did nothing wrong, it's just that either your system doesn't have any hardware monitoring capabilities, or we do not support your chip at this point in time. /etc/sensors.conf just tweaks the display for recognized chips, so it's not the problem here. Search the available technical documentation for your system for information about hardware monitoring. If your system supports it, it is probably advertised somewhere. Also check if the BIOS setup screen shows hardware monitoring data. This is usually a good indication of whether or not the system has a hardware monitoring chip. In the meantime, you might give a try to ACPI. The "thermal" and "fan" ACPI drivers may provide minimum information. Try loading them and check in /proc/acpi/thermal_zone and /proc/acpi/fan if you have something there. If you do it'll be very limited compared to what lm_sensors usually offers, but that's still better than nothing at all, especially if it turns up being your only option. -- Jean Delvare
