Welcome to HP Forums, 

This is a great place to get support, find answers and tips, 

Thank you for posting your query, I'll be more than glad to help you out

As I understand you have a screen Brightness issue,

No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution: 

Have you attempted to enable the generic PnP monitor after the update was installed?

If you haven't, here's what you need to do:

1) Search for Device Manager in Start Menu
2) Expand the Monitors section
3) Right click on Generic PnP Monitor and 
4) Click on Enable and you are good!

Keep me posted,

If the information I've provided was helpful,

That'll help us and others see that we've got the answers!

Good Luck.

Thank you for replying with this detailed response 😉 

I appreciate your time and efforts,

Here is a link that will help. Go into your power options.
Select Balanced and click Change plan settings. Click Change advanced power settings. Then save setting changes.

You could try using the Windows Update Troubleshooting tool to fix any updates that have not come through for Windows 8. 

Please restart the Notebook twice to make sure all update has been completed!

You could also try:

In the Device Manager, click the arrow next to Display Adaptors to expand that category
Right-click on Graphics and select Update Driver Software if more than 1 Graphics adapter does one at a time.
Choose the option to Search Automatically for Updated Driver Software.

The Notebook should find and automatically install the updated driver
After the installation is complete, restart your Notebook

Let me know how that pans out

I hope you have a good day ahead,

And Feel free to ask any other queries as  well,

Considering, this forum has some of the best people in the world available and ready to help.
