Surface Pro 4 brightness is locked: Can’t change the settings


Warning: Use of undefined constant user_level - assumed 'user_level' (this will throw an Error in a future version of PHP) in /homepages/13/d121821522/htdocs/mvt/wp-content/plugins/ultimate-google-analytics/ultimate_ga.php on line 524

Problem:  

A fairly new Surface Pro 4, all of a sudden, locked the brightness settings and no matter what I tried either with software or the shortcut keys on the keyboard (Fn – Del and Fn – Backspace) wouldn’t work.  Was wondering that the auto brightness settings might be keeping me from adjusting the brightness but I still couldn’t after turning it off.

Solution:

Looks like this issue, for me, was a driver problem.   I followed the instructions in the link below and I was able to adjust the brightness to my hearts content.
