Screen brightness buttons stopped working

Product Name: Pavilion 15-p097TX

I was able to adjust the brightness of my screen using the f2+f3 button but suddenly they stopped working and am not able to adjust the brightness of screen from any place neither control panel nor any other option tried some methods but they all failed

Re: Screen brightness buttons stopped working

Hi,

 

Try the following.

 

Download the Intel HD Graphics installer on the following link and save it to your Downloads folder.

 

http://ftp.hp.com/pub/softpaq/sp68001-68500/sp68117.exe

 

When done, download and reinstall the Chipset driver on the link below.

 

http://ftp.hp.com/pub/softpaq/sp73501-74000/sp73543.exe

 

When the Chipset reinstallation has completed, do not restart as prompted, instead open your Downloads folder, right click the Intel Graphics installer and select 'Run as Administrator' to start the installation.

 

When this 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.

 

Start the notebook and let Windows fully load for a few minutes before checking.

 

Regards,

Re: Screen brightness buttons stopped working

Hi,

 

No problem

 

No, it won't affect the procedure I detailed - your machine uses Nvidia optimus which means the primary display device is the Intel chip.
