cecco Posted March 18, 2016 Author Share Posted March 18, 2016 ... This is the EFI folder from usb pen I transferred and replaced in disk0s1; Jake Lo, pleasure, have a look to see if you can resolve the boot issue? Thanks in advance.

br0adband Posted March 19, 2016 Share Posted March 19, 2016 I had the issue of it going into hibernation until I put the proper DSDT.aml file in the proper location in the EFI partition - once that file was in place it booted just fine to the login screen and wasn't an issue anymore and I mean the DSDT.aml for the E6420 with 1600x900 resolution which I found in another thread, the one that comes with the boot pack doesn't work - at least it didn't for me personally). The DSDT (which is needed for the 1600x900 and the dual link aspect) I'm speaking of is in this post: https://osxlatitude.com/index.php?/topic/8686-newb-install-help-e6420-el-capitan/&do=findComment&comment=56396 Can't say it'll help you in your situation but that got me past the hibernation issue. You do have to rename it to DSDT.aml from the filename it uses. Here's my full EFI setup (doesn't include the SSDT stuff, this is what's on my installer stick only), you're welcome to try it. I have an E6420, Core i5-2540 CPU, 8GB, Intel HD 3000 graphics, and this folder for the EFI partition is what works for me now every time - it took me two damned days to get it working for my machine so maybe it'll be of some use to you. I just looked at your EFI folder, the DSDT.aml file you have is the wrong one, it's 33,853 bytes - the proper DSDT.aml for the E6420 with dual link 1600x900 Intel HD 3000 graphics is 33,882 bytes. That's how I noted you're using the wrong one. The EFI folder I'm sharing here should be used on the USB stick only because you'll need to add the SSDT.aml for your specific E6420 to the EFI folder on the hard drive after you install Clover on the hard drive - that SSDT.aml file isn't needed on the USB stick, at least I don't think it is as mine doesn't have one. Anyway, good luck, I hope this helps somewhat. EFI.zip 1 Link to comment Share on other sites More sharing options...
cecco Posted March 19, 2016 Author Share Posted March 19, 2016 hello and thank you, but the efi you attacked it's good for the 1366x768 resolution? Link to comment Share on other sites More sharing options...
cecco Posted March 19, 2016 Author Share Posted March 19, 2016 I had to install el capitan with efi for E6220 was not started because the installer since the efi e6420 was for 1600x900 resolution. Link to comment Share on other sites More sharing options...
br0adband Posted March 20, 2016 Share Posted March 20, 2016 Well no, that DSDT is for the dual link version meaning 1600x900, sorry about that. The DSDT for the 1366x768 resolution would be the one that's 33,853 bytes in size so the one that comes inside the E6420 boot pack designed for that resolution. I never used the E6220 boot pack myself since the E6420 version(s) exist. I haven't been able to get the EFI booting properly so I gave up and just went with the regular method which is working for me now. Link to comment Share on other sites More sharing options...
cecco Posted March 20, 2016 Author Share Posted March 20, 2016 this morning I noticed that sleep startup occurs only in the event of notebook plugged in, using a battery does not have this problem; suggestions? Link to comment Share on other sites More sharing options...

alcorak75 Posted April 11, 2016 Share Posted April 11, 2016 Hi all, first thanks for all of this, I managed to install el Capitan on my e6420. I wonder if you guys found a way to avoid the hibernation issue before the login screen? Link to comment Share on other sites More sharing options...
