Enabling S3 Sleep

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

Compile this SSDT with iASL or equivalant:

Source Code
``` DefinitionBlock ("", "SSDT", 2, "meghn6", "S3Fix", 0x00001000) { External (_SB_.SS3, IntObj) Scope (\_SB) { Name (SS3, One) } } ```
Rename S0 to XS0: (Goes into ACPI --> Patch)

S0 to XS0 rename
``` Base BaseSkip 0 Comment _S0 to XS0 rename; Fixes sleep Count 0 Enabled Find WFMw Limit 0 Mask OemTableId AAAAAA== Replace WFMw ReplaceMask Skip 0 TableLength 0 TableSignature AAAAAA== ```
Disable Display Logo Sign of Life in POST Behavior --> Sign of Life. This BIOS option causes issues when waking from sleep.
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:

enable-backlight-smoother
enable-dbuf-early-optimizer
enable-backlight-registers-fix
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.

SD Card

Working with RealtekCardReder.kext and RealtekCardReaderFriend.kext

NVMe SSD

The 512gb Toshiba SSD works OOTB with NVMEFix.kext

Special Thanks:

Dell for being a huge asshole
r/Hackintosh Discord for being incredily unhelpful, pls actually use your words and help instead of sending a link to the Dortania guide ffs
