Moderators Jake Lo Posted August 31, 2021 Moderators Share Posted August 31, 2021 Missing brightness and touchpad SSDT patches Try this, add the 2 ssdt to /efi/oc/ACPI and replace the config file 7290_touchpad.zip Link to comment Share on other sites More sharing options...
adam sallimou Posted August 31, 2021 Author Share Posted August 31, 2021 Hi I tried to use the files you sent me, now the brightness works but the trackpad still doesn't work and neither does the audio thank you Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted August 31, 2021 Moderators Share Posted August 31, 2021 OOhhhh, the description for the audio in the Config threw me off. It shows codec as alc225 but it actually should be alc256. I switch layout-id to 21. Give it a try, if still issue with internal and headphone try switching it to 11, 13, 14, 16, or 56 Config.plist.zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted August 31, 2021 Administrators Share Posted August 31, 2021 I would have expected the TouchPad of the 7290 to be the same as the 7490's; try the VoodooPS2 kexts I had posted in the packs of my Latitude 7490 guides.

Baio77 Posted September 1, 2021 Share Posted September 1, 2021 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: Link to comment Share on other sites More sharing options...
