Boot screen logo glitch, reduce with custom logo = none, config.plist in Clover edit
-xcpm boot argument will cause kernel panic (KP)

Summary of problems and fixes

Feature	Problem	Fix (tldr DSDT patches are your friend)
Sleep	Instant wake, device doesn't stay asleep	Apply DSDT USB3 instant wake 0x0, RTC patches
Audio	No devices in sound preferences	Inject patched AppleHDA, codec is ALC297VC_v3 (layout-id in DSDT is hex, LayoutID in AppleHDA is dec)
Battery and PM	No battery status, no native PM	Apply DSDT patch with Thinkpad x230i + Fix Mutex with non-zero synclevel
GPU	Graphics not working natively	Apply DSDT patches for iGPU, brightness HD4000 + Low resolution
USB	Ports not working/keeps device awake	Apply DSDT patches Ivy Bridge = Intel 7 series USB
Sleep/power LED	LED remains in blinking state after wake	# add these lines into method _WAK after NVSS:<BR/>_SB.PCI0.LPC.EC.LED (Zero, 0x80)<BR/>_SB.PCI0.LPC.EC.LED (0x0A, 0x80)<BR/>_SB.PCI0.LPC.EC.LED (0x07, Zero)
Brightness Control	Brightness control keys don't respond	# _Q15 (Fn+F8) brightness down key<BR/>into method label _Q15 replace_content<BR/>begin<BR/> Notify(_SB.PCI0.LPC.KBD, 0x0205)\n<BR/> Notify(_SB.PCI0.LPC.KBD, 0x0285)\n<BR/>end;<BR/><BR/># _Q14 (Fn+F9) brightness up key<BR/>into method label _Q14 replace_content<BR/>begin<BR/> Notify(_SB.PCI0.LPC.KBD, 0x0206)\n<BR/> Notify(_SB.PCI0.LPC.KBD, 0x0286)\n<BR/>end;

AppleHDA injection methods (choose one from the list)

DSDT patch HDEF + IRQ (layout-id is in hex) - preferred
Clover config.plist
HDAEnabler.kext

AppleHDA patching methods (choose one from the list)

Modify AppleHDA.kext by itself, rewrite AppleHDA.kext in /S/L/E, injecting with any method
Live patch AppleHDA.kext + injecting DummyHDA.kext with any method

Sound after sleep issues

CodecCommander loaded in /S/L/E w/ Kext Utility or with KextBeast + repair permissions/cache script

Commands to check AppleHDA, if anything returns empty = game over, restore default AppleHDA in /S/L/E and restart process

Check AppleHDA kext load status: kextstat | grep -y applehda
sudo touch /System/Library/Extensions && sudo kextcache -u /
Use DCPIManager to check audio devices and if codec ID, revision, codec name are empty = bad
Check custom loaded kext status: kextstat | grep -v com.apple

Install

Follow tonymacx86 Unibeast steps to make your USB (I don't personally use MultiBeast). http://www.tonymacx86.com/el-capitan-desktop-guides/172672-unibeast-install-os-x-el-capitan-any-supported-intel-based-pc.html
Mount EFI partition of USB with EFI Mounter v3 (from tonymacx86).
Copy Kexts to Kexts folder on the EFI partition.
Change BIOS settings (settings key is F1).
Boot USB (boot menu key is F12).

Post-install

Install Clover v2.3K R3320 UEFI .pkg - different version is OK, but must be UEFI.
Config.plist can be shared if you wish, personal preferences, except injections.
Patch your own DSDT's using guide on tonymacx86 from RehabMan, every system needs custom DSDT, no exceptions. http://www.tonymacx86.com/el-capitan-laptop-support/152573-guide-patching-laptop-dsdt-ssdts.html (trust me, it's worth the read)
Patch your own SSDT's, you could use the same if CPU models are identical. http://www.tonymacx86.com/el-capitan-laptop-support/175801-guide-native-power-management-laptops.html
Put SSDT.aml and DSDT.aml inside ACPI folder, patched, in EFI partition of OS drive.
TRIM Enabler (if using SSD, every system in 2016 should have one imo)
Disable boot graphics glitches (http://www.tonymacx86.com/el-capitan-laptop-support/175799-fix-resolve-boot-screen-garble.html) and set custom logo to none in config.plist

Patch should be entered into config.plist/KernelAndKextPatches/KextsToPatch.
