Hi,

Can you post back with the full Model No. and Product No. of your notebook - you can usually get this by holding down the fn key and pressing esc, otherwise see Here for a guide on locating this information.

Hi,

Try the following.

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

http://ftp.hp.com/pub/softpaq/sp69501-70000/sp69611.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.

http://ftp.hp.com/pub/softpaq/sp69501-70000/sp69575.exe

When the Chipset reinstallation has completed, shutdown the notebook.

Unplug the AC Adapter and then remove the battery.  Hold down the Power button for 30 seconds.  Re-insert the battery and plug in the AC Adapter.

Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu.  Press f9 to load the defaults ( this is sometimes f5, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter.  Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.

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 and let windows fully load for a few minutes before checking.

Regards,

DP-K

THIS PROCEDURE COULD NOT SOLVE MY MUTE BUTTON LIGHT PROBLEM, BUT RATHER MAKE MY LAPTOP LOOSE THE OPERATING SYSTEM AND FAIL TO BOOT FROM ANY EXTERNAL STORAGE DEVICES

Hi,

There's nothing in the procedure that would stop you're notebook booting, unless you've installed Windows 8 to a drive with a mbr - you can check if this is the case as follows.

Shutdown the notebook.

Tap away at the esc key as soon as you press the power button to enter the Start-up Menu and then select the Bios Menu ( f10 ).

Under the System Configuration tab, expand the Boot Options Menu.

Set Secure Boot to Disabled and Legacy Devices to Enabled.

When done, press f10 and select to save the changes.

You may then have to enter a 4 digit pin displayed on the screen to confirm the setting changes - enter the code and hit enter.
