I have a yellow exclamation mark in device manager stating that the SM Bus controller driver is missing.

There are two ways to update your SM Bus Controller driver: Method 1 – Download and install the driver manually Intel keeps updating drivers. To get them, you need to go to Intel’s official website, find the drivers corresponding with your specific flavor of Windows version (for example, Windows 32 bit) and download the driver manually. I got some of the drivers that were missing from the web, but cannot come up with the chipset driver from Intel for the SM Bus. The other problem I have is Dell does not recognize the service tag number or the express code printed on the back of the computer, so I can't get any help from Dell.

The SM Bus Controller is a chipset on the motherboard. Its main purpose is to monitor the voltage and temperature of the motherboard. If you see a question mark in front of the SM Bus Controller, it indicates that the hardware is not recognized by Windows. A yellow warning icon in front of it indicates that the SM Bus Controller is not installed or the driver is not installed correctly.

I have googled extensively for this and have not found a workable solution:


I just bought a new Mac Mini (2011 5,2), and tried to do the auto bootcamp download from within OS X. After 5 crashed attempts, and learning that many other people are having the same problem with Lion, I manually installed bootcamp from the software that was downloaded and then discarded by OS X (appeared to be a complete Bootcamp). Everything worked great, Win7x64 installed fine, all the drivers were found in the bootcamp files, and everything on Win7x64 works great on the Mac Mini ...


With the exception of the SM Bus Controller; it shows up as 'driver not found' in Windows. Because OS X Lion has no 'software', I cannot seem to search there for a driver as in past OS X's. From googling, it seems this is quite the troublesome driver to locate and fix, so any help or proven suggestions would be helpful. Thanks.
