Function key to mute the microphone (F4) not working

2021-04-22, 20:46 PM

Before that one windows update everything was perfect till they weren't anymore: when pressed, a function key toggle icon would pop up on my screen and it does not do that anymore. Most of them don't work at all.

Hello aaa98712h,

 

Welcome to the Community Forums.

 

For some keys that are not working, try to follow the troubleshooting steps here. https://support.lenovo.com/ph/en/solutions/ht103985-keyboard-keys-may-not-work 

 

Also, try to test the keyboard again using an external USB keyboard.

 

If the on-screen keys work along with the external keyboard yet failed to operate in the CMD lines, it can be a hardware issue.

 

Let us know how it goes.

 

Regards.
Dex_Lenovo

Hi;

 

The feature of F4 depends on the audio driver, so please firstly ensure the audio driver is installed.

Go to "Settings"->"System"->"Sound"->"Input", make sure there is at least one input audio device to choose.

As below:

 

I am looking forward your reply. Thank you.
