How To Solve SMBus Controller Error In Device Manager?

SMBus Controller

It’s possible to discover an unwanted SMBus controller issue in the device manager if you recently upgraded to Windows 11, reinstalled the Windows Operating system, or installed the most current Windows update.

On the motherboard of the computer, a chipset called the Intel SMBus Controller keeps track of the temperature and voltage of the motherboard.

When Windows does not identify the hardware, a yellow triangular with an exclamation point appears beside the SMBus Controller driver. This suggests a driver problem, such as an out-of-date or missing driver.

Fortunately, you can run an update on the SM Bus controller driver to solve this. The issue is caused by the Intel Chipset Device program failing to install the Intel SMBus Controller’s device drivers.

As a result, the OS cannot get information from the present SMBus Controller about hardware and devices. Due to the issue, Device Manager cannot display the right name for the relevant hardware.

This article will highlight a few fixes that could assist you in resolving the SMBus controller not recognized in the device management trouble.
