Device Manager displays an exclamation point for the SMBus controller or lists it under Other Devices. Hi, I installed Windows 7 64-bit on my Dell Latitude E6420 and have so far successfully installed all but one of the needed drivers. The biggest problem I have is my SM Bus Controller is recognized as 'Other Devices' with the yellow question mark.
What am I seeing?
Device Manager displays an exclamation point for the SMBus controller or lists it under Other Devices.
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. |
