Microphone mute button

[Edgar_Ekserjyan]

Please help me with the microphone mute on/off button on my laptop's keyboard.  When I press the button, the microphone does not mute and the red light on the button does not glow the same thing with the audio mute button the audio is muting but without a red glow.

Hi@Edgar_Ekserjyan, Welcome to the HP Support Community!

I understand that notebook has an issue with the mute button light not working 

Request you to follow the below troubleshooting steps.

Download the Realtek HD Audio installer on the link below and save it to your Downloads folder.

http://ftp.hp.com/pub/softpaq/sp78501-79000/sp78885.exe

When done, hold down the Windows key and press R

Into the Run window, type devmgmt.msc and hit enter.

In Device Manager, expand Sound, Video and Game Controllers.  Right click the Realtek device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.

When complete, download and reinstall the Chipset driver on the following link.

When the Chipset reinstallation has completed, restart the notebook.

When windows has reloaded, open your Downloads folder, right click on the Realtek installer and select 'Run as Administrator' to start the installation.  When this has completed, restart the notebook again and let windows fully load for a few minutes before checking the function of the mute led.

Have a great day!
