Brightness doesn't work

[Announcerlam]

It's been 7 days ever since the brightness has not been working, It's always at max and I can't change it. I tried updating the display adaptor and didn't work.

It's also not displayed in settings.

Announcerlam, Thank you for posting in the Intel® Communities Support.

I just wanted to check if the problem with the Brightness option persists and if you still need assistance on this matter?

Announcerlam, Thank you very much for providing the SSU report, we are sorry to hear the issue persists, we will be more than glad to further assist you on this case.

Based on the information showing in the SSU report, we can confirm that the graphics driver version currently installed in your system is 26.20.100.6911, which is the graphics driver provided by Acer and should be the proper driver for your system tested and validated by them.

Just to let you know, the Intel® graphics drivers are generic, meaning they might or might not work with your system but, in this case, we can always try a clean installation of Intel® graphics driver version 30.0.100.9805 following the instructions in the links below:

https://www.intel.com/content/www/us/en/download/19344/intel-graphics-windows-dch-drivers.html?wapkw=intel%20uhd%20graphics%20for%2010th%20gen%20intel%20processors

https://www.intel.com/content/www/us/en/support/articles/000057389/graphics.html

According to the SSU details, we can see that you are using Windows* 11, and the problem could be related to that, since the operating system validated by Acer for your computer is Windows* 10, that might create conflicts on the system, especially when it comes to drivers since Windows* 11 has different features and functions that the ones advertised by Acer, as you can confirm in the following link under the "Operating System" tab:

https://www.acer.com/ac/en/US/content/support-product/7982?b=1

So, we suggest additionally, to get in contact directly with Acer, to report this scenario, to check if they can reproduce the issue using the same exact computer you have, to confirm if they might have a specific graphics driver version for Windows* 11, to make sure the BIOS version currently installed in your device is the latest one or to gather the instructions on how to do that, to verify if a physical inspection is needed and for further assistance on this matter:
