Precision M4800, screen brightness


Recommended Posts


I have fresh installed Open Core with Catalina on my DELL with ATI M5100. Everything works perfect except one thing in subject.

Somebody suggest me to do patch for DSDT file and add PNLF.


Do you agree with such a suggestion or maybe some of you solved that issue?


Actually I'm looking for somebody who will fix that "problem" for me.



Best regards

Tomasz Z.
