@sadoun,

Welcome to the HP Forums!

Thank you for posting your query on this forum, it's a great place to find answers.

Don’t worry, I assure you I will try my best to get this sorted.

Awesome job on diagnosing the issue correctly and performing smart troubleshooting before posting your question on HP forums. Kudos to you on that score. 

I recommend you change the power plan to High Performance and then check whether you see the adaptive brightness option.

If you continue to face the issue, I recommend you perform a system restore back to the date when the computer was working fine and test.

Follow the steps in the below article to perform a system restore.
