thesuffering

Thats windows registry from 2012, so Id doubt it, but I dont know anything about the ins and out of it.

Any of you using a BCM94352HMB for wifi?  Ive noticed after sleep it still shows connected but it wont work.  A restart gets it going again.

Actually, I think I just solved my own issue.  I forgot to disable "Wake for Wifi Access" in Energy Saver.  I think I had this problem before.

Its always such a relief after you spend forever on it and then the damn thing finally works.  Good job!

I also keep getting this alert

Updating perms & cache doesn't seem to make it go away.

I installed mine with kext wizard, also repaired, rebuilt with kext wizard too 

 

1. Uninstalled VoodooHDA
2. Replace my DSDT with Jake's DSDT
3. Copied AppleHDA_ALC275.kext to S/L/E
4. Fixed perms and rebuilt cache with the following results

Obvious question, you did restart, right?

or somewhere in here

He said the Sierra version is hardcoded.  Id assume it would be changing one of these values?  I dont know enough about it to start fiddling with it though.

a little sensitive?  lol i had to revert back to the basic one.  I couldnt handle how sensitive it was.  Although 2 finger scrolling was so nice to have.

I think sleep is slow on this system, how long did you wait? Once sleep the front LED blinks really fast.

Perhaps it is sleeping.  After a while the LED blinks slow.  As soon as I open the lid, its back on immediately.  If i sleep from menu I have to hit the power button to get it back up.  Makes sense.

My apologies for the spoon-feeding guys. I am grateful for your time and your help.

 

I think this may be the correct results:

locals-MBP:~ localuser$ sudo chmod -Rf 755 /L*/E*
locals-MBP:~ localuser$ sudo chown -Rf 0:0 /S*/L*/E*
locals-MBP:~ localuser$ sudo touch -f /L*/E*

locals-MBP:~ localuser$ 

I'm rebooting now. Will post results.

Try the kext i attached a few posts back.  It shouldnt make a difference, but every one ive seen is named AppleHDA275.kext and not AppleHDA_ALC275.kext.  After installed, repair permission, rebuild cache, reboot.

If i choose sleep from the menu bar, it will sleep and wake up without issues.  It will not sleep on lid close though, it will only turn the screen off and back on when opened.

So, per rehabman, 10.12.4 and above AppleBacklight.kext wont work for us since our laptops probably dont use the IGPU PWM registers to control backlight,  ACPIBacklight.kext + Brightness by bergdesign is a workaround for us.

I don't seem to have either of those in S/L/E

I cant guarantee they are needed.  I believe they came from when I was trying to make it work prior to finding the 275 kext.  I looked, HardwareConfig isnt in my S/L/E, HDAEnabler.kext was.  Here it is just in case

HDAEnabler.kext.zip

Yes, I believe I have the HDA275 kext installed properly.  Check screenshot below. Is that the right one?

I believe you have the i5 version of this laptop, while I have the i7 version.  I don't think we can use the same SSDT (or DSDT, for that matter).  But to your point, I've ran the SSDTPRgen.sh script from Piker and created my own SSDT and installed into the CLOVER\ACPI\patched folder.  Sadly, it did not resolve my audio issue.

I have it named different.  Delete what you have and try installing this one

AppleHDA275.kext.zip

Not sure if its required, but Im also loading AppleHDAHardwareConfigDriver.kext, and HDAEnabler.kext

Hi Jake

 

I've installed your KEXTS and am using your config.plist file now.

I've got battery working, but still no audio devices.

My system is the i7 model, but I think that shouldn't make a difference for the audio to work.

I've included my EFI folder. Perhaps something in there might help diagnose my error.

Thanks again for your kind help.

You are missing ssdt.aml from ACPI/patched.  Im not sure it makes a difference but I noticed its missing.  Ive attached the contents of my ACPI/patched folder.

You installed AppleHDA275.kext to S/L/E and repaired permission and rebuilt cache right?

Here's my bootpack with addition to the USBXHCI_FL1009.kext from your files

The flickering only occurred after wake from sleep, fine on boot.

 

Just notice the webcam doesn't work on your files either.

I've made some progress from earlier today using the Ubuntu method to convert my disk from GPT to MBR.

I've got some tweaking to do to get Audio working, Battery percentage and some other things, but at least I'm moving forward again.

 

I sincerely appreciate appreciate all the suggestions and assistance.

Using the kexts/ddst from the above quoted post should give you working audio and battery.  I attached my config.plist since his hd3000 tweaks caused so many artifacts on mine.  Only thing i dont have working is sleep on lid close (sleep pressing the sleep button works, and audio works after sleep), and brightness

It looks something like this though:

I have a thread on bios-mods.com from last week.  Maybe if enough of us post on that thread it can pick up traction.  So far nobody has even responded . https://www.bios-mods.com/forum/Thread-Dell-XPS-13-L321X

I think I've encountered that "Boot Manager" window and wondered if it was useable for UEFI.

Is there any clues about it in the Dell documentation?

I cant find anything about it.  I definitely did boot Clover from a UEFI boot usb i had from a previous laptop, and it came right up.  This same USB wont boot from the BIOS options, so the laptop has the ability to boot UEFI and apparently Dell is hiding it and not letting it be a standard option.

So, surprising discovery.  Apparently this laptop can boot UEFI.  If you tap the right arrow rapidly on first startup it should give you an EFI boot menu.  I was able to boot a UEFI usb stick with it.  Unfortunately I cant find a way to use this exclusively over BIOS, so BIOS/Legacy is the only way to boot without intervention, but it definitely goes to say its probably just a bios unlock away.

I'm ready to try it your way. Can you describe the process to create the Ubuntu disk and convert from GUID to MBR?

creating ubuntu live usb:

https://usbubuntu.wordpress.com/make-usb/

GUID to MBR:

https://www.tonycrapx86.com/threads/success-intel-dh67gd-core-i7-2600k-hd3000-ml-10-8-2.77676/#post-520519

see step 16.

Keep in mind, install Clover to HDD after this conversion.  I did mine while it was still GUID so mines all sorts of crazy booting using clover on same partition as macos but then pulls clover config.plist/kexts from the hidden efi folder, which is a pita to mount and view until you know the trick.  Take my experience and dont do this and just install clover after the conversion lol.  I just dont really want to start all the way over.

I was testing to see if increasing the VRAM fixes the flickering. I read that it requires minimum 512MB, but since the system is soldered in with 4GB of ram and no way of adding. It just turns out it's my system. I had install it onto another L321x and no flickering.

 

Hmm, on my new install, brightness is not working either. Let me verify the other system and compare.

Have you figured out power management?  On battery, it seems to suck down extremely quickly.  I want to say it was ~10% per 15-20 minutes.  Looking at Intel Power Gadget, it appears the CPU has some kind of power management working since its moving up and down, but GPU is flat lined.

Since you've made it to the installer, what I did was open Disk Utility, and formatted the SSD as GUID and Mac OS Extended Journaled.  It installed.  Then after getting in, convert GUID to MBR with Ubuntu, install Clover, and in theory you should be good.

EAPDFix fixed sound after sleep.  Laptop sleeps and wakes fine now.
Brightness....still not working, even with the kext, patches, and ssdt
I did have to pull out the clover patches for HD3000.  System report did show 1GB video memory, but I had artifacts everywhere.  Removing those patches only gives 384MB but the artifacts are gone.

Ill have to test via my usb stick tomorrow, don't want to mess up the SSD install too much.  Tried just the ACPI/Patched and Kexts but brightness and audio stopped working after sleep.
