Mute button LED stopped working after Windows 10 April 2018 feature update.

[MyronSz]

The laptop is working fine apart from one hiccup after the Windows 10 April 2018 feature got installed. The LED on the mute button has stopped working, but the mute button does it's proper function. Does any one know what to do to restore the LED function on the mute button?  Obviously uninstalling the April feature update is not an option.

I'm guessing I won't be the only one encountering this issue.

Hi,

Try the following.

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

https://ftp.hp.com/pub/softpaq/sp80501-81000/sp80538.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, 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.
