Lenovo w530 auto brightness fix

I had a weird issue with my new Lenovo w530 laptop and windows 8.1. The screen would auto dim when I was in dark websites or when my background was gray. I tried the default solutions (power options etc) but the issue would remain. I even installed Lenovo's power manager (in compatibility mode, but seriously, don't do it!).

The solution came with a registry hack offered by Lenovo for a different laptop. You can download it from Lenovo's support, here.

Hope this saves you some hours of searching...
