Microphone and Microphone mute button on T420s (4174) not working

I've updated the latest audio driver and am having no luck.  Any ideas?

Re: Microphone and Microphone mute button on T420s (4174) not working

Hey there Robirob22 and welcome to the forums?

 

What operating system are using currently? Have you possibly tried looking at you HotKey Features Integration Drivers? Additionally, are you encountering any other problems with other buttons?

 

Additionally, ThinkVantage System Update 5.02* was released on Friday, this should help pull all of your up to date drivers. I hope this helps

 

 

*It does note, Microsoft .NET Framework version 3.5 with Service pack 1 or above is required for System Update to work Correctly. Use Microsoft Windows Update to ensure that Microsoft .NET Framework3.5 SP1 or above is installed on your system.

SOLUTION: http://support.lenovo.com/us/en/downloads/migr-74261

Install, restart, victory.

After 60+ hours of working on this, two motherboard replacements, and every bit of googling I could muster up.
