This is what happened on my E565 when I installed Lenovo PM Driver 1.67.14.05.

Go to Control Panel->Device Manager, find Lenovo PM Device under System Devices, then roll back the driver to the previous version 1.67.14.04.

Your Microphone and WiFi hotkeys should now work...

Worked perfect. Thank You. Now I just have to figure out how my Grandson either deleted or changed my sound. lost the original. No mixer totally different now. Conexant smart audio now. Was different before.
