Appreciate if  any SME  can point me in the right direction:

 

Have an e7440 ; has everything running Mojave and Clover

 

Screen is bright with no brightness control in the "display" of system preferences

No audio detected 

 

Here is what I see on system info

Intel HD Graphics 4600:

Every thing else is working.

your Config file is corrupted, looks like you added a section incorrectly or using an unsupported text editor.

Replace it or restore the original

 

Hmm, looks like your bootpack is from a Broadwell system, you need the bootpack for E7440. Check out my E7440 guide and bootpack

Just replaced the config.plist,  ACPI and kexts folders in the existing EFI from your EFI_7440Mojave.zip 

Works like a charm. Thanks again Jack.

 

If I may ask one last followup, boot up seems longer (may be there are some timeouts for which boot sequence is waiting, not sure), any way to troubleshoot the longer boot sequence? I can definitely live with 2 min boot time, though :) Good day.
