SMBus controller not detected properly
Issue:
Windows* does not recognize the SMBus controller.
Device Manager shows a yellow question mark for the SMBus controller.
Device Manager lists the SMBus controller under Other Devices.
Background:
SMBus is the System Management Bus defined by Intel in 1995. It is used in personal computers and servers for low-speed system management communications. An SMBus controller is integrated into most Intel® chipsets.
Solution:
Download and run the Intel® Chipset Software Installation Utility. This will install the chipset INF files so that Windows* properly recognizes the chipset’s built-in SMBus controller.
