[Baio77]

This report whit this file and your SSDT, no work

 

now I put the kext "BETA" 2.1.1 PS2 but same result, I really tried them all, but I can't give up now, I have to insist ......
From the vision of the ACPI origin do you have ideas ???? I have not found any ACPI folder with similar structure among the configurations found on the DELL network
I have read in some guides that removing _DSM methods is not good, so I didn't use that rename

 

This is the keyboard for brightness keys

Have you tried Karabiner-Elements.app to set the Fn keys. See my example here

[Baio77]

Jake Lo thanks for the support, for the brightness adjustment I solved it with USB mouse-keyboard, inserting the receiver and from system preferences I set everything up and it works perfectly always .........
The touchpad is missing and it just doesn't want to be activated

[Jake Lo]

What patches did you have on the DSDT?

Try removing it and just keeping the SSDT-xxx

[Baio77]

Hello Jake Lo , this my folder OEM , touchpad no work ..............

I can only tell you that I have tried every possible solution, with DSDT, without DSDT and I have also tested various SSDT-I2C solutions found on the net, but nothing is wrong
