Screen brightness not available and their change FN keys not working (OMEN by HP Laptop 17-cb0xxx)

[Sokkary]

I bought a new Omen 17 inch laptop. The screen keeps flickering while using it, I assume that's due to room light and auto-brightness feature, because when I change the amount of light in room, the flickering almost fade away. I tried adjusting the brightness by using FN+F1 & F2 but nothing happens, and I can't seem to find the brightness settings in Windows 10, it's disabled or something by HP!

How can I adjust the brightness and make it manual, not automatically detected + how to make the FN keys work for the screen brightness (FN+F1&F2)?

Note: the rest FN keys are working properly (e.g. volume... etc.)

My Operating System : Windows 10 Home 64-bit

Microprocessor : Intel(R) Core(TM) i9-9880H CPU @ 2.30GHz

Any idea how to fix this?

Thank you.

Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

On most laptop keyboards, you’ll find shortcut keys that allow you to quickly increase and decrease your brightness. Often, these keys are part of the row of F-keys–that’s F1 through F12–that appear above the number row on your keyboard. To adjust the screen brightness, look for an icon that corresponds to brightness–often a sun logo or something similar–and press the keys.

• Go to Control Panel > Hardware and Sound > Power Options, then click on "Change plan settings" next to your active power plan. Click on "Change advanced power settings." Scroll down to Display, then under Enable adaptive brightness, switch it off for both the battery and plugged in modes

Hope this helps! Keep me posted for further assistance.

As I mentioned in the original post the function keys ain't working for those 2 keys only, it works with volume for example, but when I click on those screen brightness function keys it did nothing.

Tried the steps in your trouble shooting and can't find under display anything like (Enable adaptive brightness), the only setting under Display is (Turn off display after), see the screenshot attached.

No new updates ... System is up to date... I don't know what to do!

The windows I got with the device is Windows 10 Home Edition, does this by any mean could be a reason? Does the home edition come with less features or something!? Just wondering.
