Follow instructions from here to debug issue, make sure HDMI connection is connected

Replace with this DSDT DSDT.aml.zip

In Config file, under SSDT sortOrder, add SSDT-PNLF.aml In either /L/E or /S/L/E, wherever you installed these kexts, remove the following: NullCPUPowermanagement IntelBacklight AzulPatcher4600 WhateverGreen NvidiaGraphicsFixup For audio, I see you have both AppleALC.kext and AppleHDA_ALC255.kext. Use one or the other, not both Remove then, repair permission and rebuild cache. Lastly, your system has an AMD graphics card as well as HD5500. You might be using the wrong bootpack that is HD5500 only. I see your AMD graphics loading in IOReg, this will drain your battery quickly if not disabled.

See here how to attach file

Which version of Sierra? 10.12.6? Follow instructions from here to debug issue Have the HDMI monitor connected when you run the debug. Don't do anything when the debug is running until it's done.

The patches can be done on the Fly with Clover. No the patches are for single / dual link for different resolution, it will not fix the artifacts issue if you go beyond A12. You'll need to go back to A03 to reset some settings and then to A12. A few were able to use latest BIOS version if they replace the display panel with one that's not originally from Dell. Although I had recently read another member has update to the latest BIOS running High Sierra and no issue there. I had not confirm it and not sure if he has different brand of panel either For touchpad, use this one. Will support up to the latest High Sierra.

Marked as solved.

Did you change bios settings? make sure UEFI and AHCI are selected

Boot to Clover, hit F4. Continue to OSX, compress and attach /EFI/Clover/ACPI/Origin here for patching

1) If you look at the time you place the system to sleep, it no longer show as failed in the log. The log shows previous failed attempts. 2) Apply Rehabman's [usb] USB3_PRW 0x6D (instant wake) 3) What happens when you close the LID? Does it only sleep when you select from Apple Menu?
