Several Lenovo-sourced drivers not WHQL signed

2011-08-26, 8:25 AM

I had to rebuild my W500 after my Hitachi 500 started giving read errors.  This means downloading a lot of drivers from the Lenovo site directly.  Several aren't signed, which causes some annoyingly difficult to fix errors.


  • switchable Graphics driver (7vd617ww.exe)  driver version 8.792.5.0

The artifact is that attempting to launch the catalyst control center results in a "" error.


  • The Conexant 20561 SmartAudio HD driver version 

This is loaded with system update 4 and does not have a verifiable signature either.  The "properties" dialog reads:


Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)
