EEPROMs are data storage chips, not sensors. sensors-detect lists them because they are on the I2C bus and sensors can live on this bus too, and we have been hosting the eeprom driver. It seems to confuse lots of users for years, so I'll edit sensors-detect to make it clear that EEPROMs are not sensors. > I do not want to believe that there is not a way to check the CPU > temperature / there are not sensors on the motherboard... it would > be very odd if this is the case. > > Below is the output from lspci, sensors-detect and sensors. > > Is there anything I can try and see why no sensors are found? > Am I missing something? No, there actually doesn't seem to be any hardware monitoring chip on your system. The I2C (actually SMBus) bus driver works fine, but there are no hardware monitoring chips connected to it. And there is no known Super-I/O chip either. It isn't uncommon at all for laptops - in fact most laptops don't have accessible hardware monitoring chips. You should try ACPI instead. Load the "thermal" and "fan" drivers, and look in the /proc/acpi/thermal_zone and /proc/acpi/fan directories, respectively. It's nowhere next to what lm_sensors can offer on supported systems, but better than nothing. On both laptops I have, this is the only way to get the system temperature. You could also contact Lenovo for technical information, just in case. -- Jean Delvare
