For brightness control add this SSDT in ACPI, remove SSDT-XOSI and rename Xosi in configplist, let them know if brightness works SSDT-OCWork-dell.zip

https://drive.google.com/file/d/1u36v83vcebJQPF8YH6RqYvrRs8mPk_TN/view?usp=sharing test this ioreg please , if it doesn't start use my ACPI files + Kext folder

post ioreg + efi and list hardware

This rename for GPRW Ioreg is not good, wrong SMBios 16.2 is for Ice Lake CPU, use 16.4 or 16.1 https://drive.google.com/file/d/10EKHFG8WbqNusmLfdik7mWLnKSFIZj7j/view use this file ACPI and Kext Pass the EFI

post ioreg please , use this SSDT . The choice of SSDTs is not accidental, I know DELL machines and all these SSDTs are needed. add rename in config for SSDT GPRW and SSDT XOSI. SSDT GPRW and SSDT PMCR they help the laptop sleep although this also depends on other factors Archivio.zip For the trackpad as well as Ioreg I would need to know the precise model, if ALPS are developing a Kext in these days, but now gestures work, only the trackpad buttons are missing

Set SMBios Macbookpro 15.2 and use this ID

I think the best solution is to use SSDT, in any case both Opencore and Clover

Test this https://drive.google.com/file/d/10EKHFG8WbqNusmLfdik7mWLnKSFIZj7j/view?usp=sharing if it does not start try to create 1 EFI with SSDT which are in the ACPI folder and the kext i put you in my EFI, ioreg when you started with the files i passed you

This is wrong Describe the specifications of your Lenovo, precise model CPU, if equipped with Discrete GPU (Nvidia or AMD) etc etc is detailed The order of the kext this should be, and also ioreg, in my opinion things are missing to fix: trackpad as a minimum it would be useful to extract ACPI and Log files with this EFI Debug EFI Debug 0.7.3.zip

Test this OC 0.7.3 EFI.zip this for fix HPET

For BT in Monterey https://github.com/acidanthera/BrcmPatchRAM Test This EFI https://drive.google.com/file/d/1BqRfskspTd8EM4gDn-3oPw_MIjxsfqCG/view?usp=sharing if it starts run ioreg and list known problems . If it does not start block photos

TEST this file in your EFI , ioreg this file EFI.zip

you have a Mald0n DSDT, it is NOT possible to restore this DSDT is full of various patches pass EFI + ioreg and let's use SSDT to boot Win from Opencore

test this https://drive.google.com/file/d/1iAy-aG-6ZPTJs9To3W0LOCQFY2aDnJPJ/view?usp=sharing

For trackpad buttons, see the trackpad system preferences menu. List what does NOT work in the last EFI for sure the audio ....

EFI.zipTest this for trackpad ioreg

I would need ioreg EFI trackpad working, I would like to understand, many Latitudes have trackpad problems like in your case

if you can do a test with this EFI if it starts ioreg, I fixed some things both in config and acpi level, if it starts ioreg and let them know if you solved with trackpad keys EDIT EFI.zipNew EFI correct error driver

Debug EFI 0.7.2.zip Use this EFI Debug, extract useful information for those who want to help you have a Hack, extract ACPI Origin from the bios + various other information about the system in general, once extracted the files placed here Log.txt and Sysreport folder

EFI.zip Test This , ioreg if it start , As you can imagine the EFI I pass you are all the same they differ only on the trackpad, slowly I'm running out of tests, but let's not despair .

still no working trackpad ?? if you tell me the audio layout that works I select it in the config so as to always pass you a better EFI

EFI.zipTest This , ioreg if it start

ioreg please

EFI.zipTest this EFI. I have rebuilt the I2C1 device, as it is explained https://github.com/Baio1977/OC-Little-Translated section https://github.com/Baio1977/OC-Little-Translated/tree/main/05. Laptop-specific Patches/Trackpad Patches/I2C Varius TrackPad Patches . SSDT-I2C1-TPDX(Dell Latitude 7290).zip SSDT trackpad sample. Thanks for the patience you are showing, eventually you too will get your Hack working

After analyzing EFI and Ioreg, for the trackpad we have to reconstruct the device or in any case do some tests and see if they give positive results Do you also have a touch screen ??? In the picture the I2C1 device of your Hack:
