[Solved] Dell E6440: No Wifi/Ethernet/sleep under Big Sur (OpenCore)

[dgccr]

Putting together a little hackintosh for my son and running into some small hiccups which I hope you guys can help me with. I found an EFI file
that was built for this model and created my USB for Big Sur, mounted the EFI Part an copied the files into it and booted up ( worked perfect ).

 

Dell Laptop - https://www.dell.com/support/home/en-us/product-support/servicetag/0-c1pLdndLcUpXcDZIVkxHY3VaY3Y5Zz090/overview#

Post - ( EFI File OC_0.6.6_Release.zip )

After that I mounted the EFI on the local drive, copied the files and now im booting fine off the internal hard drive ( sweet )! Everything seems to work except a for the following :

 

- Sleep ( If I sleep the laptop or close the lid it will never come back unless I reboot )

- Wifi ( had an intel card which I know doesnt work, Ordered a Dell DW1550 )

- Ethernet

 

 

The strange thing is it looks like it sees the adapter fine but it will not go active when I plug in a wire, Also the serial # is 000000000 should I fix that or will it only effect iMessage which I dont plan on using..

 

Any help is greatly appreciate as I continue to research each of these.

Re: Ethernet, the Latitude E6440 is fitted with an Intel i7-217LM Gigabit Ethernet interface. The certainly was supported, either by Miele's IntelMausi kext (make sure you use the latest version ) or good old AppleIntelE1000e kext. You'l find the former in the Web and the latter in the packs I has posted in my old E6440 guide.

 

Re: Sleep, it should work as long as you have properly configured CPU power management. With Big Sur, you should no longer have to disable hibernation either.

 

But, again, unless you post a zipped copy of your OpenCore setup (EFI folder with config file + ACPI folder + kext folder), not much we can analyse and not much we can provide in terms of assistance.

Thanks for the response, Attached is the config I used for this computer.. My apologies on missing some details, I have been out of the game for quite some time and just started tinkering again.

Graphics settings are incorrect with no need to patch fbmem or stolenmem on HD4600 iGPU.

Update your add-on kexts to latest versions, you're using old or very old versions.

[dgccr]

So replace all the kext files with newer versions? Do I have to copy them into the EFI folder on USB and boot, Then copy to the local EFI and reboot without USB or can I copy them right into the local EFI on my internal disk?

 

Would that be the process?

 

Im assuming I can remove the GPU settings, Just have to read up on the process ( so much have changed in the last few years when I last dabbled in these setups ).

[Hervé]

I suggest you read up the Dortania documentation as a general refresher course.

Why consider complicated routes for kexts when all you need is the simplest path? Just make sure to reset NVRAM at OC Picker when you reboot.

 

Re: HD4600 iGPU, all you need is the usual that's been used for the last 10 years and nothing else:

AAPL,ig-platform-id        0600260A        DATA
device-id                  12040000        DATA
framebuffer-patch-enable   1               NUMBER
framebuffer-con1-enable    1               NUMBER
framebuffer-con1-pipe      12000000        DATA
framebuffer-con1-type      00080000        DATA

Ill review the documentation provided asap and see if I can figure it out, Its quite the opposite Im not trying to take the more complex routes im just not well versed in the process & trying to keep it simple.
Was hoping if its a common laptop where its been done a ton of times already ( I swear ive read over almost all E6440 posts ) it would just be a matter of, Check this post, or swap this kext and this kext and reboot.

 

I work in enterprise IT on the troubleshooting side so I get it, I also get that sometimes the documentation can make things seem completely more complex then they really are and why I asked the questions since this is not something I do often.

 

If this was something I would be doing everyday id have the process down pat as well as where to look etc, this is something I do once every few years and im a bit rusty ( got 90% of the way there already ).
Laptop boots fine just need to fine tune the remaining few issues.

 

Please dont take any of the above wrong way at all,  I dont expect you or anyone to do the work for me was just looking to save some time or trial/errors if its just a matter of swapping a few files or making a few edits to be 100%.

 

Thanks thus far!

If you really want to be on the safe side of things, you may of course try/test your revised setup out of a USB boot key, then apply the proven setup to your internal disk. But we're only talking kexts updates here, not experimentation with new kexts.

[dgccr]

Ahh good Idea and thanks! I pretty much have it down to the following:

 

1 - Find updated Kexts ( ill research, you stated mine were old )

2 - Fix Ethernet

3 - Fix Sleep

4 - Serial # ( does this only matter for imessage / facetime ) ?

 

The rest of the stuff is all working and the laptop boots fast & snappy. Battery Percentage / Volume Controls, Brightness, camera etc etc all works.

 

Thanks!

I re-read one of your earlier posts where you mentioned "no need to patch fbmem or stolenmem on HD4600 iGPU." is there any easy way to remove these patched settings or a process you can point me to?

 

Im sure your replys are spot on but unless your fully versed in OpenCore / modern hackintosh's its alot to take in. Im a very technical person so I can follow posts / diy's etc. Those Dortanio docs are very informative
its just alot of reading and learning for a setting I will need to get right once hopefully and then never revisit.
