[REQ] Intel 4400 DSDT Backlight Patch

2 posts in this topic

Hello everyone!


I have an Asus Q550LF which has an Intel HD4400 graphics card. I need some help with my graphics card, primarily my graphics card.


I've already patched my DSDT and SSDT-3. However, the other SSDTs have errors that I am unable to fix. And, I think I messed it up anyways.


Also, this thing has a dedicated NVidia card which may cause some issues. Can you guys please help me? Thank you so much!!!


Attempted Patches:

I've attached my patched DSDT and patched SSDT-3, but the others are un-patched. I am able to provide the clean SSDT-3, but I am unable to provide a clean DSDT due to some system-critical patches.


I have been using ACPIv4 to do the edits, which may be part of my issue.


Once again, thanks for all your help.

Use Clover and dump the native tables of your Hack by pressing F4 at bootloader GUI screen of Clover. Then zip the files in /EFI/Clover/ACPI/origin and send us. Only that way we can help. Also you should use the IntelBacklight.kext not the GenericBrightness one. Also ACPI 4.0 i way out of date. Use only ACPI 6.1 and the latest iasl compiler.
