E6430 Backlight unstable on Big Sur installer


Recommended Posts

Hi everyone am trying to install big sur on my laptop but currently using Mojave which is working perfectly with the exception of touchpad and Atheros AR9485WB-EG Wireless card.

 

I followed this  and downloaded EFI files for OC bootloader.

i generated my SSDT.aml as instructed in the post and replaced it.

The main problem is after OC verbrose screen, the backlight will go off immediately on the apple logo. The temporal workaround to bring the backlight back is "fn + arrow up" but it will go off randomly again and if i don't do that quickly the laptop will go to sleep and i will have restart the installer again.

 

What i have tried so far;

regenerated my own SSDT.aml

tried latest whatevergreen and lilu kext

tried flashing back and forth dell BIOS version

Tried recommended bios settings from this site

Tried Herve's EFI file in this post and touchpad is not working

All didn't solve big sur backlight abnormality 

 

So my question is, is there a way to fix the backlight issue with a kext or drivers ?

If am to stuck with mojave, is there a way to use whatever is making my touchpad working when booting big sur using EFI from here

Is there something am missing?

Is there working EFI available for my model?

Note: Mojave works with any bios version i flash regardless of warning to flash A12

 

Thanks everyone.

Backlight should work OOB with the right settings in place: Capri framebuffer usual patching + SSDT-PNLF.

TOuchPad should also work OOB with the VoodooPS2Controller available in my E6230 guides; the kext works 100% in all E6x30 models of the range. Maybe yous is faulty or possibly disconnected; check that out.

Latest BIOS are Ok to use for sure as long as you apply the FBMem patch that reduces memory from 16MB to 8MB (glitchy graphics otherwise).

Thanks for the reply, how do i apply "Capri framebuffer + SSDT-PNLF" to my efi folder to solve the issue.?

Do i need to generate SSDT-PNLF for my model as i did with SSDT-PM.aml?

I don't mind much about touchpad as i use external mouse most of the time.

Glad to know bios version is not that much of a problem as am free to upgrade back to A23.

I know i sounds lame as am kind of new to hackintosh world.

ACPI tables:

  • You already have the SSDT-PNLF in your OC ACPI folder, so all is covered.
  • You need to remove SSDT-PLUG though and disable it in your OC config.

Graphics/Capri framebuffer properties:

  • All suitable/necessary properties are already injected in your patched DSDT (see _DSM Method under IGPU device).

Kexts:

  • Remove VoodooHDA and replace with AppleALC (its' a Lilu plugin). Audio will then work with alcid 12.
  • You shouldn't use USBInjectAll alongside USBPorts. Latter is usually generated having initially booted with the former. So try without USBInjectAll to begin with.

 

I invite you to consult my E6230 guides for details of the kexts I've used and what they do. Versioning is also detailed in case you need to update those that may be old.

 

It's important that you get NVRAM working as this will ensure active/selected screen brightness is retained throughout reboots or sleep/wake cycles.

hey sorry for late reply, i was reading to equip myself with some basic as am very dumb.

 

1. i removed SSDT-PLUG from the acpi

2. replace VoodooHDA with latest AppleALC from here

3. i update the config with Plist Editor Pro

<dict>
				<key>BundlePath</key>
				<string>AppleALC.kext</string>
				<key>Comment</key>
				<string></string>
				<key>Enabled</key>
				<true/>
				<key>ExecutablePath</key>
				<string>Contents/MacOS/AppleALC</string>
				<key>MaxKernel</key>
				<string></string>
				<key>MinKernel</key>
				<string></string>
				<key>PlistPath</key>
				<string>Contents/Info.plist</string>
			</dict>

and disabled VoodooHDA.

4.Since am good on Capri something, i left it untouched

Lastly i am confused of this "It's important that you get NVRAM working as this will ensure active/selected screen brightness is retained throughout reboots or sleep/wake cycles." How do i make the nvram working?

thanks mate, but i have decided to give up after reading, testing and failing for days on all kinds of tutorials and EFI folders. At a point my hdd and modular bay stopped working.

My laptop wont boot anymore with those things mentioned above connected and i flash BIOS versions again, finally downgrading it to A03 saved my ass.

Am gonna cool down for awhile and wait for someone's already working EFI folder for my model or someone generously prepare one for me.

I understand i am a total noob to this that's why everything seems difficult and always failing.

Even catalina won't install.

Thank you man for your help.

NB: i spent several days on dortania without success😄

@truceFR

Give this a try.

Files are defaulted for the following configuration

BIOS A24

i5-3340M

1600x900

If your display resolution is lower, then use Config-LoRes and rename it as Config

I also include DSDT-A23 for BIOS version A23, you'll just need to rename it in the Config file

If you have different CPU other than the ones I included, i5-3340M and i5-3320M, then you could use SSDTPrGen.sh to generate your own

Place it in ACPI, rename it to whatever you like ...maybe SSDT-PM.aml? But make sure to rename it in the Config file as mine is defaulted to i5-3340M.aml

Upgrade your BIOS to A24 or A23 to use my files otherwise you probably get the same automatic sleep right after boot.

I see you have A20, I could probably patch that for you, but I'll need the vanilla DSDT exported from your system.

Good luck

@Jake Lo

I tried it by making the following changes

 

A23 bios and 1366x768 resolution

so i did the following in propertree on windows

 

Deleted these from ACPI folder
1. DSDT-A24.aml
2. SSDT-i5-3320M.aml
3. SSDT-i7-3520M.aml
4. ssdtPRGen.sh

 

and i updated the your original config.plist file not the LoRe.plist with changes made above
1. ACPI>ADD    changed DSDT-A24.aml to DSDT-A23.aml
2. left SSDT-i5-3340M.aml as it is same as mine

 

I didn't succeed in booting to the installer interface.

Had some errors which i screenshot for debugging and to track down the error.

I am attaching them in their order of occurrences and a log from OC.

 

After failure on bios A23 i upgrade it A24 and reversed the changes made earlier but i faced the same error.


But i noticed ACPI>DELETE you have "Drop CpuPm" and "Drop Cpu0Ist" set to "false"

 

Anyway i love the bootloader theme🙂
