Hi frankricher,

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!

Hi frankricher,

Thank you for the picture. It appears that there may be a hardware issue with the backlit keyboard. You may want to try a Performing an HP System Recovery (Windows 😎 to factory settings to see if this repairs the issue.
