For what ever reason the brightness control in the System Preferences no longer works. I think it may be related to these two previous issues that I posted about in the past https://osxlatitude.com/index.php?/topic/9131-solved-e6420-monitor-sleep-turn-off-on-boot-fresh-install-of-el-capitan/ https://osxlatitude.com/index.php?/topic/9504-solved-black-screen-on-e6420-sierra-upgrade/ I am using the following DSDT because the one in Jake Lo's Sierra bootpack was not working despite me having updated to the same bios version that the bootpack is meant for, as discussed in the above threads. https://osxlatitude.com/index.php?/topic/9131-solved-e6420-monitor-sleep-turn-off-on-boot-fresh-install-of-el-capitan/?p=61321 But that DSDT was patched back when I was on El Capitan, do I need a new freshly patched DSDT for Sierra? Also why does the LoRes DSDT in the Sierra bootpack not work for me? This has been an issue for me since El Captain, is there something different about my E6420's monitor? It uses the Intel HD 3000 with the max resolution of 1366x768.

Update, I got everything working, I used the El Capitan DSDT for A22, with the Sierra config-LowRes from the new bootpack, then I made sure my AppleHDA was vanilla by replacing it with one I extracted from the InstallESD.dmg for Sierra. Then I reinstalled the AppleHDAIDT in /Library/Extensions and I re-ran the permission script a couple of times. Both audio and video work now, thank you.

I don't have either of those installed. I never touched AppleHDA when I was running El Capitan, but IDK what exactly AppleHDAIDT does. Does AppleHDAIDT patch AppleHDA on boot or something, should I try to install a fresh AppleHDA by downloading the Sierra installer and extracting it from there? I'm sorry I don't have a strong technical knowledge about this.

Yes and yes.

Sorry, I misunderstood. Here you go. rebuilding //System/Library/PrelinkedKernels/prelinkedkernel kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext IOAHCISerialATAPI_Injector.kext kext file:///Library/Extensions/DisableTurboBoostBattery.kext/ is in hash exception list, allowing to load kext-dev-mode allowing invalid signature -67030 0xFFFFFFFFFFFEFA2A for kext AppleHDAIDT.kext KernelCache ID: 262A522CE5DA9D9D468623F699E13C57 symlink("/System/Library/PrelinkedKernels/prelinkedkernel", "/System/Library/Caches/com.apple.kext.caches/Startup/kernelcache") failed 17 (File exists) <createPrelinkedKernel 2795> kextcache updated critical boot files, requesting launchd reboot Finished

That is after I ran the permission script and rebooted.

No what I mean is that there is no on-board audio.

The old config with the new DSDT doesn't work, but the new config with the old DSDT does. So what exactly do you want me to send, the old DSDT? The old DSDT is located here https://osxlatitude.com/index.php?/topic/9131-solved-e6420-monitor-sleep-turn-off-on-boot-fresh-install-of-el-capitan/?p=61321 You had patched it for me a couple of months back. Also what am I missing for getting the audio working, it I noticed that audio works via hdmi but not through the on-board speakers. I copied the files in the LE folder to /Library/Extensions and I ran the following script in the terminal. What I'm a doing wrong? #!/bin/bash if [ $(id -u) != 0 ]; then echo "You need to run this script as root. Type sudo -s, enter password and run this script again." exit fi sudo chmod -Rf 755 /L*/E* sudo chown -Rf 0:0 /L*/E* sudo chmod -Rf 755 /S*/L*/E* sudo chown -Rf 0:0 /S*/L*/E* sudo touch -f /L*/E* sudo touch -f /S*/L*/E* sudo kextcache -Boot -U / echo "Finished"

I just tried my old El Capitan Config file and DSDT and it worked. Now what do I do?

Yes I did.

I tried fn-insert but it made no difference, the backlight is definitely on because the screen is providing visible light, the only problem is that it's black. I checked the display prepane and the sys profiler, both the built-in lcd and my tv are listed. It also appears that I am able to change the output resolution via the display prepane, but the built-in lcd remains black while only the resolution on my tv changes.

Hi, I recently tried to upgrade my El Captain installation to Sierra after noticing that Jake Lo had updated his guide to include an e6420 bootpack for Sierra. From what I can tell things are working so far except for one major thing. The screen does not work, it’s a black screen and I can only use the laptop via the hdmi out. I do not think this is a bios issue this time, because I saw that the bootpack was for bios version a23, so I updated my bios to a23 beforehand. My monitor’s resolution is 1366x768 and I am using the DSDT-LoRes from the new bootpack, but it would appear that the resolution that is being output, at least via hdmi, is 1360x768, maybe this is the reason why I am getting a black screen? I’ve attached a picture of my tv saying that the resolution is 1360x768, just to show where I got that number from. Any help would be greatly appreciated.

It appears to have worked, I should probably test it a bit more to be sure. But it seems to work, thank you.

My E6420 is using bios revision A22. Here is my extracted DSDT. DSDT.aml.zip

Hello I've decided to try my hand at installing OS X on my E6420 for the 2nd time. I just installed El Capitan 10.11.5 using Jake Lo's guide. Everything appears to be fully functional except for one thing, my laptop monitor will always turn off during boot. The system is running fine in the background but my monitor just turns off for whatever reason. Unplugging and repluging the charger is my current work around. This works when have access to a wall outlet, but otherwise I am stuck with the monitor off. I am using the e6420 bootpack with the DSDT-LowRes.aml as my display's resolution is 1366x768. Also I do not have optimus on my laptop.

It boots fine with no nullcpu as long as I boot using the -v flag, I don't need -f or -x. So I just edited my org.chameleon.Boot.plist to always boot in verbose mode. I don't understand why it works only in verbose mood since I thought that all this did was show the log while booting, if anyone can explain it to me it would be helpful. I am aware that I need a patched AppleIntelCPUPowerManagement kext but there was one included in Jake Lo's bootpack and thats the one I've been using since before starting the thread.

After finally fixing my graphics driver I now am having kernel panics on boot. I can avoid this by either booting into safe mode, or using nullcpupowermanagement.kext. But on the post-installation directions of Jake Lo's guide it says it's ok to "Rename NullCPUPowerManagement.kext to *.bak from /Extra/Extensions." as long as you "Restore it before doing any updates to prevent KP." After I updated to 10.10.5 and reinstalled the kexts from SLE, and the updated ones from Jake Lo's thread, I then renamed it back to NullCPUPowerManagement.kext.bak, it boots correctly if I boot into safe mode and sometimes if I do a normal boot after booting into safe mode, but after that I get kernal panics and I have to use NullCPUPowerManagement.kext to do a normal boot again, and my battery indicator of course no longer shows up. I know it's not as huge of an issue as before, but if anyone can help so I can get my battery indicator back it would be greatly appreciated. I already have an SSDT.dsl, but do I need to generate another one after installing updates, will that make a difference? If it helps here is my Extra folder, is there anything wrong with the files in there? Extra.zip here's another pic this time booting using -v Edit I found out how to look up the kernel log, so I'll post that here Oct 11, 2015, 8:11:20 PM kernel[0]: Kext loading now disabled.

I tried copying and pasting some text from the kernel log after delete -v.rtf after delete no -v.rtf

The thing is, I already did this, I only have intel hd graphics 3000 and the res is 1366x768. I renamed the DSDT-E6420.aml film to DSDT.aml and I moved it to the /Extra folder, but my graphics driver still won't load Edit currently trying to update to 10.10.5 so I can try the updated kexts for 10.10.5 to see if they make a difference. will report back when done Edit 2 After the update my graphics driver is suddenly working. Have not even installed the updated kexts from the guide thread. Everything seems to be working fine now. Only issue that I've noticed is the battery indicator doesn't seem to appear. Edit 3 works fine Forgot to change NullCPUPowerManagement.kext to NullCPUPowerManagement.kext.bak now that i've done that the battery indicator works fine

I tried to start over and reinstall 10.10, and I still get stuck on boot. I'm using this bootpack, I tired to follow the instructions but i'm not sure that I did it right https://osxlatitude.com/index.php?app=core&module=attach&section=attach&attach_id=6552 I tried to boot using -v -f GraphicsEnabler=Yes And it worked but my graphics driver still isn't working, nor is sound. How can I fix this? Edit I see that I forgot to copy over the smbios.plist and the org.chameleon.Boot.plist. Now that I've done that -v -f GraphicsEnabler=Yes no longer works and I have a new error. HELP PLEASE! Edit 2 I'm no longer getting the sandbox message. I was able to get into the OS using -v -f -x, but I still can't normal boot. Here is the new picture from booting using -v. It doesn't look too different from the first one, but then again this is all greek to me. Edit 3 I seem to no longer be able to enter the os even on safe mode using -v -f -x Edit 4 So I booted in to single user mode and I used rm -rf AppleIntelSNBGraphics.kext rm -rf AppleIntelSNBGraphicsFB.kext to delete my graphics driver, I am now able to boot in to Yosemite, but obviously I have limited graphics. Where do I find the proper Intel driver and if there is a special way to install it how do I do that. For whatever reason the AppleIntelSNBGraphicsFB.kext provided in the bootpack doesn't work Edit 5 I used these instructions to install the orginal kexts but it still didn't solve anything, I don't know how to get my intel hd graphics 3000 to work http://www.tonycrapx86.com/yosemite-desktop-guides/150458-restore-original-kexts-patched-appleintelsnbgraphicsfb-kext-appleintelframebuffercapri-kext-mistake-using-multifail.html Edit 6 I tried Clover as Gia Cat Lang recommended and all I got was a kernel panic when trying to boot, so I reinstalled Chameleon, I'm back to normal but still no closer to getting my graphics card working what am I doing wrong?

I'm not sure exactly why but my dell e6420 is hanging on boot for 10.10. I'm able to get in the OS if I use -v -x on chameleon, but on a normal boot it hangs, here is a picture I took using -v. Apparently it has something to do with bluetooth, but my laptop does not have that feature. Any help would be greatly appreciated.
