ACDindia Posted November 25, 2014 Share Posted November 25, 2014 Hey guys! I have been struggling with this weird issue since last 15-20 days..! Now I think I have narrowed down the error.. My system: Dell Inspiron 7720 Laptop Intel 3rd Gen Core i7 3630QM Intel HM77 7 series chipset Intel HD4000 + nVidia GT650M DDR5 2 GB optimus (Never works, I know) Using Clover UEFI Bootloader on UEFI system I have a DSDT for my laptop. But have tried with and without it too. What happens: The Intel HD4000 works with QE/QC for a couple of times after fresh install. Then suddenly it stops working, although it is detected as usual. AGPM Capri and HD4000 kexts are loaded still I get no QE/QC... AGPM says "Unknown Platform"... I used a LegacyAGPM.kext to get around with that. Now when the QE/QC is broken, I reboot the computer and in Clover deselect "GeneratePStates" and "GenerateCStates".... QE/QC is back!!! Again after couple of reboots, it is broken!!! Now again i select "GeneratePStates" and "GenerateCStates", QE/QC starts working for few reboots! What is my problem??? Please help!! Anyone????

ACDindia Posted November 26, 2014 Author Share Posted November 26, 2014 about agpm, use the original and just replace gfx0 for igpu in the dsdt. Hmm... The problem is that I use MacBookPro9,1 SMBIOS which is closest to my laptop's configuration.. And AGPM kext doesn't have an entry for MAacBookPro9,1....

ACDindia Posted November 30, 2014 Author Share Posted November 30, 2014 it doesnt matter. replace on dsdt gfx0 for igpu. Hey! It doesn't make any difference!!! Thank u for the suggestion anyways!!! What the hell is wrong!!! QE QC Works for a couple of times with GeneratePstates and GenerateCstates then stops working.... then if I disable GeneratePstates and GenerateCstates, starts working again! then stops again... repeat the method by enabling GeneratePstates and GenerateCstates and it starts working for a couple of times... then again disable them both.... This cycle!!!!! Any clues ???????? Link to comment Share on other sites More sharing options...
