z1326 Posted July 27, 2016 Author Share Posted July 27, 2016 Sorry, I can't. I only use Enoch, never Clover... You can consult my Enoch-based E6440 guide or JakeLo's general Latitude/Inspiron Clover guide.I read your post of e6440 and according to the picture you uploaded you disabled the discrete graphics in OS X 10.10,however there's no graphics related SSDTs in your boot pack,how did you do that?Did you disable 8690m though DSDT?Also I found that before auto shutdown I always get the following information in console. Failed to connect (_consoleX) outlet from (NSApplication) to (ConsoleX): missing setter or instance variable Could you think of something? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted July 27, 2016 Administrators Share Posted July 27, 2016 No, I did not disabled anything at all. The discrete AMD 8690M GPU just does not register in SysProfiler. You're giving too much importance to this. Link to comment Share on other sites More sharing options...
z1326 Posted July 27, 2016 Author Share Posted July 27, 2016 I know this laptop (E6540) have 2 versions. The early version used LVDS screens. However the haswell don't support LVDS so Dell used a eDP to LVDS chip to transfer the eDP signal to LVDS.And the late version used eDP screens. So they don't need the transfer chip anymore. The screen just get signal from haswell cpu.My laptop is the early version and it has the eDP to LVDS transfer chip. Is it possible that this is the reason?And I'm eager to find out how to make it not register in SysProfiler. Link to comment Share on other sites More sharing options...
z1326 Posted July 27, 2016 Author Share Posted July 27, 2016 Try the config in the E6540 bootpackOk, I'll try it as soon as I get home.BTW,Do you have E6540?And if yes,does it contains AMD 8790M? And I'm curious that how did you make the discrete graphics "invincible".(If I used your DSDT,the discrete graphics is still there even I add the disable code to SSDT-8.)

Administrators Hervé Posted August 1, 2016 Administrators Share Posted August 1, 2016 My last shot at it. Place attached patched tables in your ACPI/patched folder (keep a backup of your existing files of course). Patched_tables.zip Link to comment Share on other sites More sharing options...
z1326 Posted August 2, 2016 Author Share Posted August 2, 2016 My last shot at it. Place attached patched tables in your ACPI/patched folder (keep a backup of your existing files of course). Patched_tables.zip I've tried this and the discrete graphics remained in the SysProfiler. I checked SSDT-8 and I didn't find the _OFF code. What did you do to disable the discrete graphics? And when I try to disable it by adding _OFF into SSDT-8 _INI. The whole process is: SSDT-8 _INI----_OFF code----SSDT-9 _OFF---SSDT-8 SGOF So it is the SGOF code that actually disables the 8790M. However once the SGOF code is applied the auto shutdown problem will come. I think the auto shutdown problem is something about power management and the SGOF code might call to some code related to EC. But I'm not a professional programmer and I can't dig up about this. Could you check the code and try? Link to comment Share on other sites More sharing options...
z1326 Posted August 2, 2016 Author Share Posted August 2, 2016 I've tried these days and I assume that since the fan speed will get high before auto shutdown the reason could be related to power management or CPU. So I checked the console and found that these codes would show up before auto shutdown. Process launched [1] disabling system-wide I/O ThrottlingProcess launched [1] disabling system-wide CPU ThrottlingSo do you know what is the mistake?
