travis_de Posted August 11, 2021 Author Share Posted August 11, 2021 I have successfully installed it on my laptop but let me ask that the brightness is not full. How to fix this. I tried this EFI and the brightness is full: https://github.com/r33int/Hackintosh-Dell-Latitude-E5440 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted August 11, 2021 Administrators Share Posted August 11, 2021 That EFI folder does not appear to use/inject SSDT-PNLF table which, by far and large, is necessary to obtain brightness control. After you've added that table and rebooted/reset NVRAM, check if your Display PrefPane presents the brightness control bar or not. It should. Once you've asserted you have brightness control, your keyboard brightness keys may not be operational but other keys/key combinations probably will. You mar refer to this guide to remap brightness control keys. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted August 11, 2021 Moderators Share Posted August 11, 2021 Replace SSDT with this one Your audio is ALC292, not ALC295 Try installing ALC_Fix See here for guide under post installation SSDT-E5440.aml.zip Link to comment Share on other sites More sharing options...
