Hi Chunhao, > The version of lm_sensors I'm working is 2.9.0.

The attachment is the detect result log, you may refer > to it and check the script again. The log shows the following error: Error: First argument not a number! Syntax: i2cdetect I2CBUS I2CBUS is an integer Installed I2C busses: i2c-0 smbus SMBus I801 adapter at 0500 Non-I2C SMBus adapter This means that the version of i2cdetect you are using it too old. Make sure that you have no old version of this tool lying around. The error causes the SMBus not to be probed at all, which is probably why your W83792D chip was not detected. With a newer version of i2cdetect installed, sensors-detect should work fine (hopefully). -- Jean Delvare http://khali.linux-fr.org/
