What am I seeing?
Device Manager displays an exclamation point for the SMBus controller or lists it under Other Devices.
How to fix it
Download and run the Intel® Chipset Software Installation Utility so Windows* properly recognizes the SMBus controller.
|Note||SMBus is the System Management Bus used in personal computers and servers for low-speed, system management communications. A SMBus controller is integrated into most Intel® chipsets.|
