Brightness setting with f2-f3 is not working for Pavilion15

[antonio19812]

It has been suddenly impossible to set the screen brightness both with f2-f3 and from the control panel or the power management section.

I have never updated any driver since when I bought my laptop at the end of 2014. Could that be the reason? what could I do?

The screen works properly and I can see it clearly, but this brightness problem is quite annoying..

Hi,

Download and reinstall the Intel HD Graphics driver on the following link.

When the reinstallation has completed, restart the notebook and let Windows fully load for a few minutes before checking.

ok, I will try to do it.

can you explain to me why did it happen so suddenly??

Hi,

There are a few possibilities, though most likely would be a bad update to the gpu driver.

Hi!!

your solution really fixed my problem, so thanks !!!

I would ask you if you suggest me to install the updates that are displayed as available in my HP-support tool.

I know that sometimes the upgrades can bring some problem to the operative system, but as I have never upgraded any driver or else for my laptop since I bought it, I would like to be sure about what to do.

Thanks again
