gpspl Posted March 2, 2016 Share Posted March 2, 2016 Hi, I've instaled 10.11.4 on my Lenovo W520 but i can't set right SMBIOS (now i'm using MBP10,1) because when i set it to MBP8,1/2/3 all i get is black screen after verbose. All is working (QE/CI, audio, etc) but PM no because i'm using wrong SMBIOS so no sleep or speedsteping. What is a problem and what i can do?

En0r1m Posted March 2, 2016 Share Posted March 2, 2016 First, open multiple topics It will not make people help you faster, removing others and keeping only this, and secondly, post your files: SSDT, DSDT and config.plist for an analysis. Link to comment Share on other sites More sharing options...

gpspl Posted March 3, 2016 Author Share Posted March 3, 2016 Yes it's working. In w520 you can disable optimus and leave only nvidia gpu (or intel gpu if you want :>). All is working except for PM because i'm using wrong SMBIOS. Link to comment Share on other sites More sharing options...
vusun123 Posted March 3, 2016 Share Posted March 3, 2016 Mac Pro 3,1 or Macbook Pro 10,1 should fix the black screen issue. I have uploaded a DSDT made for the W520 ( the Quadro 2000M model ) in the T420 thread so make sure to check that out Link to comment Share on other sites More sharing options...
gpspl Posted March 3, 2016 Author Share Posted March 3, 2016 Try these SMBIOS settings; 'should fix your black screen issue with Quadro 1000M. smbios.plist.zip I'm using clover not chameleona :< Mac Pro 3,1 or Macbook Pro 10,1 should fix the black screen issue. I have uploaded a DSDT made for the W520 ( the Quadro 2000M model ) in the T420 thread so make sure to check that out Now my SMBIOS is set to MBP10,1 so no blackscreen problem. I've alredy patched my DSDT (all working - gpu, usb, audio,backlight,battery etc but no PM) but on this SMBIOS I can't enable speedsteping and sleep (laptop just wakes nothing in console - so no common usb wake problem) Link to comment Share on other sites More sharing options...
gpspl Posted March 3, 2016 Author Share Posted March 3, 2016 It does not matter that you use Clover; I did say to use those settings, you can set them up manually in Clover. Ok :>, so is there any way to enable PM? Link to comment Share on other sites More sharing options...
gpspl Posted March 3, 2016 Author Share Posted March 3, 2016 speesteping and sleep. Now i have only x8 x30 x32 steps, and sleep isn't working (laptop goes to sleep but wakes after 1s) - nothing in console so no usb problem (i think so... :>) Link to comment Share on other sites More sharing options...
lukerus1 Posted March 3, 2016 Share Posted March 3, 2016 Hello, I'm facing a similar problem with the black screen. Also having W520 with 1000M. I tried similar fixes as you did, but not changing SMBIOS. Now I tried to use your config and DSDT but the result is the same (in verbose I can see that nvdagf100hal is loaded and then the screen turns black). Have you made any changes to anything else in order to get the display working? Thank you in advance. Link to comment Share on other sites More sharing options...
lukerus1 Posted March 3, 2016 Share Posted March 3, 2016 I haven't yet. But I tried pure 10,1's SMBIOS without success either with 1000m card nor integrated HD 3000 card. That is kind of weird since gpspl used this without gpu related problems... With pure 8,3 SMBIOS integrated card works fine (laptop LCD only). I will give your SMBIOS a try and will see... Thank you.

lukerus1 Posted March 4, 2016 Share Posted March 4, 2016 Thank you for the info. I tried your suggested SMBIOS but without success. I tried also iMac13,2 SMBIOS as I saw it working at somebody on insanelymac. Without success either. It would be OK to work with integrated gpu only, but my displayport monitor is not recognized. I followed topic about installing os x on thinkpad t420 with uefi only, but unfortunately it doesn't work. Maybe I could manage to make working some of the previous versions of os x. For example Mavericks and then move on... Link to comment Share on other sites More sharing options...

Hello, I finally managed to get both GPU and SpeedStep working (at least I hope... ). There`s no need of DSDT GPU injection, just leave the device as is and let Clover do the magic. Use this config, just make sure you don`t use NullCPUPM kext. Sleep works too. Link to comment Share on other sites More sharing options...
lukerus1 Posted March 6, 2016 Share Posted March 6, 2016 Forgot one more thing. You have to patch applegraphicdevicepolicy plist to match mbp8,3 board id. Link to comment Share on other sites More sharing options...
la0011 Posted March 24, 2016 Share Posted March 24, 2016 Hi lukerus1, can you post your DSDT/config.plist/smbios ? I'm in the same boat, W520 with Quadro 2000M and black screen issue ... Link to comment Share on other sites More sharing options...
lukerus1 Posted March 25, 2016 Share Posted March 25, 2016 Here you are. Use the attached script to generate your own SSDT.aml. Ignore the smbios mismatch error (just say yes to it). Archiv.zip Link to comment Share on other sites More sharing options...
la0011 Posted March 28, 2016 Share Posted March 28, 2016 Thanks lukerus1, I assume you've set Optimus to Discreet only and Nvidia Web Driver is selected via Control Panel / NVRAM? Will give it a try later today! Link to comment Share on other sites More sharing options...
lukerus1 Posted March 28, 2016 Share Posted March 28, 2016 Yes, discrete only and I don't have any Web drivers. I'm also digging into the brightness settings. I will tell you if there's some success. Link to comment Share on other sites More sharing options...
la0011 Posted March 30, 2016 Share Posted March 30, 2016 Hmmm, still comes up with a black screen. Is there anything Nvidia related in your DSDT? I tried both yours and my one, no difference. Just curious if the "magic" is just in the SMBIOS settings in config.plist. What screen do you have? Is it FHD as well? And which Bios version are you using? Thanks! PS Getting a bunch of LPC errors during boot, which FakeSMC.kext do you use? Link to comment Share on other sites More sharing options...
lukerus1 Posted March 30, 2016 Share Posted March 30, 2016 Make sure you don't use IntelBacklight kext. I have no gpu related fixes in the DSDT. Try also using external DP monitor or putting the laptop on sleep and then waking it up. Link to comment Share on other sites More sharing options...
lukerus1 Posted March 30, 2016 Share Posted March 30, 2016 Also try extracting your EDID using different OS. Everything else is done using Clover. (See config). I don't think that BIOS version is responsible for it, but you could try updating it. I will post my FakeSMC. One more question. Does the black screen appear right after the booting process, or it takes some longer time to switch from the verbose screen to the black one?

la0011 Posted March 30, 2016 Share Posted March 30, 2016 Hi lukerus1, thanks for helping and taking the time to reply. Good hint with Intelbacklight, I'll give that a try. It switches to a black screen after a while, before that I see error messages regarding AppleLPC (PM seems to work though), then nothing happens for a bit and the boot process seems to be finished. Usually I get messages regarding WLan (channles blablabla) before the screen turns black. I did reset my BIOS to defaults, just to make sure there's nothing weird going on there. Of course I changed relevant settings back to what they should be (AHCI, Discreet Graphics, VT-d). I did extract the EDID for my screen a while back and been using that since. Tried yours, too. Also tried external monitor and sleep/wake before, with the same result. Link to comment Share on other sites More sharing options...
lukerus1 Posted March 30, 2016 Share Posted March 30, 2016 If there's a delay between finishing the booting process and the black screen, it will be likely the IntelBacklight if I can remember well. Use single user mode to remove it. If nothing helps, I will try to simulate the problem on my system and I will let you know. Link to comment Share on other sites More sharing options...
