Best practices for resolving Lenovo Dynamic Brightness System issues

A clean and tidy computer is the key requirement for avoiding problems with Lenovo Dynamic Brightness System.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time.
