why can't I adjust the brightness of my screen on my

I have a HP Envy dv7 Notebook PC. It recently just downloaded the new HP Assistant and I wanted to adjust the brightness because it was too bright for the dark room I was in. I tried using the F2 and F3 keys to lower the brightness and I tried to adjust it from settings and control panal but the brightness doesn't adjust when I move it up or down. I tried shutting down my computer and restarting it but I still can't adjust the brightness. Help!

Hello missrodgers92.

What version of Windows are you using?

What is the product number for your notebook?  This document can show you where it is located.

Have a great day.

Hello again!

Try reinstalling your notebook's graphics driver.  Here is a link.

Let me know the result and have a wonderful day.  :)

Hi diezel. Your notebook has either AMD or Intel graphics. AttackofZaq's suggestion of a driver reinstall is a good idea.

Here is a link to the driver page. Just scroll down to 'Driver - Graphics (2)' and download and reinstall the drivers for your graphics adapter.
