Got the dreaded "SMI_IsSupport() failed." error trying to update the BIOS on my BRAND NEW Yoga 13. After several tries, and calling Lenovo's premiere tech support, I was told it was a hardware issue, and I woud need to send my unit in for warranty repair.
I"m particularly sure that this is not a hardware related issue, is there anything that I can look into or do before I finally send in for service?
Download the 66cn55ww_x64_en.exe file from the Lenovo Support Site. (Or please click the Link below) http://download.lenovo.com/consumer/mobiles/66cn55ww_x64_en.exe
Launch the executable, and it will unzip all of the files into C:\BIOS\66CN55WW. It will run automatically and fail with the above error.
Once that happens, go to the BIOS\66CN55WW folder, and RIGHT CLICK on the 66CN55WW batch file,
Select "Run as Administrator" from the drop down, and follow the instruction until complete.
