When installing a new operating system on your computer (or updating an existing one), the user may notice that in the “Device Manager” next to the device called “SM Bus Controller” there is an exclamation mark in Windows. This usually indicates problems with the installation or correct operation of the corresponding driver, which ensures stable functionality of the CM bus controller on your PC. Below I will explain what kind of driver this is and where you can download a free SM bus controller driver for Windows 7 x64.
This driver ensures the functionality of the “SM Bus Controller” also known as the “SM Bus Controller”. The full name of this controller is “System Management Controller”, which means “System Management Controller”.
On the SM motherboard, the bus controller is presented in the form of a chipset, the main function of which is to control the voltage and temperature of the motherboard of your PC. An important function of SMBus is also to supply the OS with information about the devices installed on the computer, which allows you to correctly display information about them in the Device Manager.
The SM Bus controller is often integrated into Intel hardware, so if your motherboard has a chipset from Inter, then you are likely to see the “SM bus controller” I’m considering there.
Full operation of the “SM bus controller” is ensured by the corresponding driver from Intel, which has several versions. If this driver is dysfunctional (or absent), an exclamation mark on a yellow background will be displayed in the “Device Manager” to the left of the “SM bus controller” device. And in the information about the driver of this device, the user will find a message about the absence of an installed driver in the system and error code 28.

It also works with volatile controllers, such as the subsystem of a laptop computer responsible for recharging the battery, devices with temperature and/or voltage meters. Among other functions, the bus is responsible for the correct operation of the COM port and USB device. In addition, the controller strives to ensure that the following device parameters are processed correctly:
It is worth mentioning that programs for the controller are located among the drivers intended for the operation of the chipset. It is advisable to install a suitable driver on Windows from the CD that comes with the laptop or motherboard. Or, as an option, on the device developer’s resource, select the required chipset from the catalog and download the application. There are very rare cases when the installation needs to be done manually (via the "Device Manager" by selecting file location).
On the current page, software for updating drivers for any PC is available for download. The Auslogics Driver Updater program will allow you to restore the functionality of inactive elements of the hardware component of the user's computer, quickly detecting devices, as well as missing or outdated software associated with them.

Sometimes when viewing Device Manager in Control Panel Windows 7 you may notice a yellow exclamation mark next to the title SM tires, or rather, its controller. This means that there is a problem with its functioning and you need to install driver. What kind of controller is this, how can I update the driver for it?
Auxiliary SM Bus is designed to collect and transmit information about various devices included in the system, their operation, status, and parameters. Most often it is used in computer motherboards.
The bus is used to determine the specifications of the equipment connected to the computer. It allows you to:
It was originally developed by the American corporation Intel for its devices, but is now used on the equipment of most motherboard manufacturers. Software for correct operation of the bus is included in the chipset driver package.
It is best to install the driver from the disk that came with the motherboard. If it is lost or cannot be installed, then using the name and model of the motherboard, you need to find the drivers on the manufacturer’s website, download and install.
Often, after computer users reinstall the operating system, they are faced with a fairly common problem, which is that they need to additionally install hardware drivers. And while performing this task, many PC users are faced with the need to understand what an SM bus controller is.
In fact, such equipment actually exists, which is why many people are concerned that it does not work correctly. But does it have any serious significance for the smooth and full functioning of the user’s PC? Or the presence of this device is only necessary “for show” so that all equipment and the corresponding drivers are installed correctly.
In simple terms, an SM bus controller is equipment that is present on the motherboard of a laptop or desktop computer. It is used for the correct operation of the motherboard's south bridge and network adapter.
This is an auxiliary chipset element whose purpose is to collect various local data, such as indicators of memory blocks or the temperature of the processor case.
How to install this driver and where can I download it from? You can find the driver on the original disk that is included with each motherboard. The best option is to run all the original disks that contain the drivers during the installation of the Microsoft Windows platform.
Another solution to the problem is to download the necessary drivers from the official resource of the company that produces the motherboard.
But is an uninstalled SM bus controller a serious cause for concern? In most cases, users simply do not use it when using a laptop or desktop computer. Therefore, if you could not find a suitable driver, do not worry about it.
