Hi@AliamMan, Welcome to the HP Support Community!

I just want to make sure I understand your issue. Your backlight on your HP ENVY TouchSmart 15-j122tx Notebook PC keyboard is not distributing the light evenly. I will try my best to help you with this issue.

Here is a document for Display and Keyboard Dims Using the Proximity Sensor that may help with adjusting the lighting. 

I hope this helps, please let me know how it goes.

Thank you and have a great day!

I worked on behalf of HP.

Hope this helps! Keep me posted.
