My SM BUS CONTROLLER is also missing.  

 

Machine: Lenovo w530

OS: windows 7 64bit 

 

Any help finding chipset download would be greatly appreciated.  Could not find on Intel's site.

 

Notes: 

 

  • Recently had to rebuild drive
  • Yes, I am still running Win7, but purchase extended suppport from MS (for 1year)

Hello,

 

Have you tried using Intel's Driver Support Assistant from https://www.intel.com/content/www/us/en/support/detect.html to locate the correct chipset driver?

 

Regards,

Thank you for your response.

 

Yes, I did install the intel driver application, but unfortunately it does not locate the driver for me.  

 

I have also manually searched Intel's drivers, downloaded several, but have been unable to get any to install.

Intel and others seem to have removed all references to Win7, now that it's been legacied by MS.

 

You can find the "Intel Chipset INF utility" (version 10.1.1.42 dated July 2017) usable for Win7 here at the CNet site.  The SM Bus Controller is supported by the chipset, not a specific driver. Running it should clear up your W530 Win7 issue.

Thanks, DSperber!

 

The Intel Chipset INF Utility solved the SM Bus Controller for me and my Lenovo ThinkPad W530 i7 with Win 7 Ult. The Chipset drivers from Lenovo did not solve the problem, sadly enough.

 

I am from the industry - Sillycon Valley, since 1981 - and I find the abandonment of technology as a 'new and improved' item comes to the market a shame.

 

Keep up the good work!
