Hi @Jsandhu,



Welcome to the HP Support Community!


I read that your HP 15-r036TU Notebook is not letting you adjust the Brightness. I am seeing that if you change the power plan options to balanced option in the Notebook it will help. Here is a link that will help.


Go into your power options. Select Balanced and click Change plan settings. Click Change advanced power settings. Then save setting changes.


Please let me know how this goes.
