Baio77 Posted October 11, 2021 Share Posted October 11, 2021 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 Link to comment Share on other sites More sharing options...
Lorys89 Posted October 11, 2021 Share Posted October 11, 2021 @djuby try this efi EFI 3.zip Link to comment Share on other sites More sharing options...
djuby Posted October 12, 2021 Author Share Posted October 12, 2021 @Baio77 I am unable to download the SSDT. Can you please post it again? @Lorys89 Tried the EFI - booted OK. USB mouse stopped working. Trackpad was really slow and no clicks or gestures. Sound was very low, even when I turn it all the way up. No brightness control.

Baio77 Posted October 12, 2021 Share Posted October 12, 2021 Please reply with Ioreg for any tests you are asked to do, otherwise it remains difficult to understand where corrections need to be made. Lorys changed audio layout, you used 99 if it was better to correct it yourself in Lorys89 EFI. If the trackpad is working the problems you have fix them from the trackpad preferences panel at 99% Link to comment Share on other sites More sharing options...
djuby Posted October 12, 2021 Author Share Posted October 12, 2021 Thanks Baio77. I'll make sure I provide all information in my posts. Current status - all is working fine, except for brightness and sleep/wake up. Attaching EFI... EFI.zip ... and the IOReg.

Baio77 Posted October 12, 2021 Share Posted October 12, 2021 Your Dell has TB ports, so curing sleep could be cumbersome and complex , but let's see what you can do later we leave you files to try Link to comment Share on other sites More sharing options...
djuby Posted October 12, 2021 Author Share Posted October 12, 2021 Hi Baio77, I am ready to try anything. Question, will disabling the TB in the BIOS help with sleep/wake up? Link to comment Share on other sites More sharing options...
