SM Bus Controller - message saying drivers needed

by on ‎07-12-2010 07:28 PM - edited on ‎08-12-2013 10:32 PM by Lenovo Employee Sat_TC (118,037 Views)



What software do I need for this? I have a 7417-TPU T400, running XP Pro 32 bit.



With regards to the SM Bus Controller you can find the chipset drivers here for your computer/OS:

Download, run to extract and then install.


If you are not very familiar with Thinkpads ,  download and install System update first:


This tool will give you the option to download and install all the drivers/lenovo software for your computer/OS with a few clicks. You select and deselect what you want and don't want and click to continue. Then you don't need to download and install each file manually.

What's DOS?

I have a T500 with the same issue but the above information did not fix the problem.  Any help would be appreciated.

g50-80; the same issue (after "upgrading" BIOS) - SM Bus controller driver not found. What helped was instaling chipset drivers (there where from Intel, but found on lenovo's site).
