Microphone gone after disabling and re-enabling it in BIOS (Security - I/O Port Access menu)

Windows doesn't detect it anymore, and the microphone-mute button is dead.

It depends

- have you tried "Scan for hardware changes" from the root icon in the tree of device manager

Other devices such as camera and wireless come back after disabling and re-enabling them in bios, but microphone doesn't. Not that I really need it, but this is weird.

I would call the Technical support line.

- They should have the answer since they live and breath with these day in/out and have access to info knowone else has

- they can do the same thing on the model (with the factory image you have). We assume you have the factory image!!!

- once testing in the lab they can get back to you

 

There is very little you can do:

- double check the BIOS retained the change you last made and IT IS STILL ENABLED

- double check the list in Device manager as to the status (if they're on the list still)

 

There is little substitue for hands on trouble shooting and I have know idea what might be missing. All be it you've not supplied any information on any aspect of the machine, configuraton or operating system you have. Nor weither you're using the Win 7 factory image of which type etc

 

Call the support line. A competent tech should get you going after a few reboots. If not call back and get someone else who knows what they're doing/have it escalated to someone who knows.

Did you ever get this to work?  I'm having the exact same problem on a Lenovo W520 laptop.
