driver sm bus controller - can't find!

2018-03-05, 0:27 AM

Hi All,

 

I'm hoping someone can help me out.  I just installed a fresh copy of windows 7 64 bit on a thinkpad t400 4236 and I'm missing the sm bus controller driver.  I've looked on the lenovo site under the chipset drivers and downloaded Intel Management Engine Firmware 7.1 for Windows 8 (32-bit, 64-bit), 7 (32-bit, 64-bit), Vista (32-bit, 64-bit), XP (32-bit, 64-bit) - ThinkPad and it's still in the device manager list as other devices with an exclamation mark.

 

Can anybody point me in the right direction?

 

Thanks for your time!
