Enabling S3 Sleep

Warning: This step is crucial. Your system will not sleep if you do not do this.

  1. Compile this SSDT with iASL or equivalant:

    Source Code 
        DefinitionBlock ("", "SSDT", 2, "meghn6", "S3Fix", 0x00001000)

    {

    External (_SB_.SS3, IntObj)
    
    Scope (\_SB)

    {

    	Name (SS3, One)
     

	}
    
 
}

  2. Rename S0 to XS0: (Goes into ACPI --> Patch)

    S0 to XS0 rename 
    <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

  1. Disable Display Logo Sign of Life in POST Behavior --> Sign of Life. This BIOS option causes issues when waking from sleep.

  2. Disable hibernation in macOS:

     sudo pmset -a hibernatemode 0

Audio:

This laptop uses ALC289, layout-id 11.


iGPU Patching:

Besides the normal IceLake patches mentioned in the Dortania guide, the XPS 13 needs a few extra fixes:

  1. enable-backlight-smoother
  2. enable-dbuf-early-optimizer
  3. enable-backlight-registers-fix
  4. Use framebuffer 0200518A

Misc:

  • Add -noDC9 to your boot-args to prevent panic after waking from sleep
  • Dell's firmware has problematic USB detection in F12 boot menu. To ensure a consistent experience, make sure the drive is partitioned as FAT32/GPT.
    • If you can't get it to work no matter what you try (flipping orientation, switching ports, etc etc) reset NVRAM.
  • Make sure to toggle the "Advanced" switch in the BIOS.
  • F12 for boot menu, F2 for BIOS

Power Management:

  • Please refer to zearp's undervolting guide.

  • I found the following to be pretty stable on my machine, YMMV and please be careful when doing this.

      ./voltageshift offset -80 -75 -75

  • For CPUFriend, make sure the LFM is 1.00 GHz, you can customize the other settings to your liking. I reccomend full power savings for quieter and cooler operation.

  • It is reccomended to disable camera, fingerprint, and touchscreen in BIOS settings to maximize battery life.
