Which boot loader are you using, Clover or Chameleon/Enoch?

No, the DSDT normally remains untouched throughout for graphics. It can need updating on occasions; for instance the USB device for El Capitan.

Did you patch your DSDT for HD3000 layout and screen res at all? What LCD screen resolution do you have? Anything beyond 1440x900 usually requires to set DualLink to true.

Re: keyboard layout, you may want to consider the ISO layout of your VoodooPS2Controller if that's what you use: https://osxlatitude.com/index.php?/topic/8641-proper-keyboard-layout-recognition-with-voodoops2controller-eg-latitude-e-series/ In Lion 10.7.5, you have to run AppleACPIPlatform kext v1.3.5 or v1.3.6 from SL, otherwise your laptop would KP. Check your hibernation mode, your power savings settings in the PrefPane and verify that you do have native CPU SpeedStepping in place (correct tuned FakeSMC kext + correct SMBIOS profile). https://osxlatitude.com/index.php?/topic/2673-performance-tuning-with-fakesmc/ If you have all that but still experience issues with sleep causing immediate wake, then the issue is DSDT related and I'd suggest you post your current DSDT.

Probably an Optimus-related issue. Did you tune your laptop for HD3000 graphics? Do you get graphics acceleration at all?

Mobo baking is indeed not a permanent fix and one will require to re-bake again; can be sooner, can be later. It really does depend on the quality of reballing and long term usage but it does fix the GPU issue. I've had to re-bake my D630 about 3 times in the last 4 or 5 years. 10 good minutes at 200C, then stop the oven, open its door and leave the mobo cool off. Make sure to have native CPU+GPU SpeedStepping in good working order + fan free of any dust clog + non-dry thermal paste onto CPU+GPU. If you heavily use your laptop, pay a little annual visit to the mobo inside the casing.

Normally, it should be the same set of files as for EC, except the temporary MBP7,1 SMBIOS only for installation (return to MBP5,1 afterwards). Well, it was for my D630...

Cards working under Sierra in an identical manner as under El Capitan (no controller listed in SysProfiler). They just require the Generic USB3.0 XHCI kext. Here the GMYLE adapter:

If you read the thread I linked above, it says not to install/run EDP as it is not necessary. Unfortunately, you seem to confirm that EDP remains screwed up for our original D Series these days. Just run myHack and if it does not prompt you to install the Extra folder, re-run myHack and choose "Install Extra" in the myHack menu, pointing to the downloaded pack from my D6x0 thread. that's all you need to do. Same goes for Chameleon, myHack may not install Chameleon automatically. So don't hesitate to download version r2468 and install it manually.

myHack is based on Chameleon. Stick to that for a Lion installation. It'll be much easier than Clover.

Please install Lion with myHack tool + the D620 GMA950 HiRes Lion pack available here. Forget Leppy's old SL guide, it's deprecated nowadays. Guidance for myHack installation is available in the EDP menu at the top of your screen.

Look up for the patch for the well-known final stage boot glitch. Basically you need to binary patch the IOGraphicsFamily kext.

The order of the permissions repair commands (sudo chmod/sudo chown) does not matter as long as they're done ahead of the sudo touch commands (their own order does not matter either) and the final sudo kextcache command.

Where did you install your add-on kexts? /S/L/E or /L/E? Maybe Kext Wizard does not work well in EC 10.11.5. Personally, I've not used tools like this for years. I'd invite you to follow the manual method described in the guide you followed, starting with permissions repair: sudo chmod -Rf 755 /S*/L*/E* sudo chown -Rf 0:0 /S*/L*/E* sudo chmod -Rf 755 /L*/E* sudo chown -Rf 0:0 /L*/E* sudo touch -f /S*/L*/E* sudo touch -f /L*/E* sudo kextcache -Boot -U / This method pretty much garantees good cache rebuild. if you encounter errors (it can happen and that's why I prefer the manual method to tools like Kext Wizard), retype the last 3 x commands. Booting without cache is "just" a lot slower than with it; that's about it.

If you can boot EC with -f flag (i.e. without cache), try to rebuild your cache once booted up: sudo touch -f /S*/L*/E* sudo touch -f /L*/E* sudo kextcache -Boot -U / Which version of Enoch are you running? You can safely use any recent version, including latest version r2839 posted at IM. One cautious thing you can do is to keep all working kexts in /E/E as a rollback in case you screw things up at some point. Kexts in /E/E can safely be injected at boot time and in safe mode through the following Enoch parameter+flag set: KernelBooter_kexts=Yes -f Add -v for verbose mode.

Which BIOS version are you running on your E6420? Could you post a copy of the raw/extracted DSDT so that we compare it with the patched one you're using?

Whatever the version, OS X would run like crap without graphics support. It's pointless.

You'd have needed to purchase SL as detailed here: https://osxlatitude.com/index.php?/topic/5561-buying-older-mac-os-x-versions/ But it's useless as you have the unsupported Intel GMA4500-based model, i.e. you would waste your time trying to install OS X on it.

Redo whatever you did to get audio working in 10.11.

Just follow the guides for any other HD3000-only model of the E6x20 family. You'll just have to adjust your DSDT for screen resolution if it's above 1440x900 and set DualLink to 1 (true).

On a D830, you need to disable hibernation as per the 3 command lines you found in that linked article. You do not need the BIOS password, that only applies to the GM945 chipset models (D430/D620/D820/etc.). Make sure you do not use NullCPUPowerManagement kext (normally, you don't). The above commands you posted are only applicable when you make changes to kexts. They repair permissions and rebuild the kext cache.

Probably a corrupt installation package then. Try and redownload it.

Make sure you've set HDD mode to AHCI in BIOS. If your partition table is of MBR type, you may need to apply the MBR patch to your installation.
