The Intel SMBus Controller is a chipset on the computer’s motherboard that monitors the motherboard’s voltage and temperature. A yellow triangle with an exclamation mark next to the SMBus Controller driver means that Windows does not recognize the hardware. This indicates a driver issue, for instance, an outdated or missing driver. Fortunately, this can be fixed easily.

What is the reason for the SMBus controller error?

The Intel Chipset Device software does not install device drivers for the Intel SMBus Controller and this leads to the error (the yellow exclamation mark). This prevents the current SMBus Controller to transmit device and hardware information to the OS. The error prevents the driver to display the correct name for the specific hardware in Device Manager. This post will highlight a few solutions that may help you fix the SMBus controller not recognized in the device manager error.
