Thanks a lot Metzz71.

Hello Metzz71, I use VoodooBattery and it works fine if I start the computer with "-f" boot flag. For your sleep, are you using NullCPUPowerManagement with sleepenabler or did you perform some dsdt editing? I would also want to get my computer to sleep. Thanks.

Igashu, I have attached an updated AppleHDA to post #67 that I made yesterday and it is working in place of VoodooHDA. To get it recognized and working though I need to set boot flag "-f" when the computer starts. Try it and let me know how it goes. It is still a work in progress as I am learning the stuff while working on it. I discovered a very good thread on Insanelymac here: AppleHDA patching by bcc9. Try it and let me know how it works for you. In addition when I have noticed that when I ignore the cache with "-f" flag at boot time, I always get the battery indicator to work properly. Does your trackpad work with swipe or not? I wonder if someone has it working. Thanks.

Sorry Igashu, I will send you again all the files I changed in my whole S/L/E and Extra folders to make things easier. I might have omitted some vital kexts while sending the first package. I am also using chimera (chameleon, stolen and rebranded) from multifail Mountain Lion from tonycrapx86. I could send you the whole folders (S/L/E and Extra) but the size is more than 280MB for S/L/E alone. The one thing that you need to make sure is that in your SMBios your model is MacBookPro8,1 because I edited the two NVS 4200M kext files to reflect that. I remember seeing the error related to the AGPM Controller unknown platform. Once I edited the two files and run kext wizard to repair permission and my ML drive everything went well afterward. Thanks.

Thanks Igashu, Please don't use the included DSDT.aml file as it is not completely done. I noticed that it affects my laptop performance. I also patched my Vanila DSDT with DSDT Editor just for shutdown and it is now working. I may need to write a few steps regarding what I am currently doing to make my e6520 work. In the meantime please find attached the kexts I edited before seeing a normal boot work with graphic and audio. I remember particularly that I had to do a binary patch to: AppleIntelCPUPowerManagement and for the remaining listed kexts I only made changes to the info.plist : NVDAGF100Hal, NVDAResman, NVDAGK100Hal, NVDANV50Hal. My model in SMBios is MacBookPro8,1. I am attaching the above files along with all other files that I found during my process. Please let me know if they will work for you. I still need help with sleep and native battery management, so if any of the more experienced folks on the forum can help I will appreciate very much. I saw the following interesting post useful DSDT patches for sleep even though it is for an older model and my knowledge in DSDT patching is limited. Please let me know if this works for you as well. Thanks. E6520 nVidia NVS 4200M pack.zip Working_e6520_AppleHDA.kext.zip

It is working under Mountain Lion with the latest 10.8.1 without any problem for now. Could you share again your current DSDT? I have tried to patch my vanila DSDT with DSDT editor for the shutdown without success so far. Thanks.

Hello Igashu, Does your e6520 shutdown with your patched DSDT or not? I am now 85% done with mine, graphic card works very well. My nVidia NVS 4200M is fully recognized with proper VRAM 512MB. I had to patch both the following kexts: NVDAResman and NVDAGF100Hal for my NVS 4200M by following this post NVS 4200M Kext patch. I was also getting AGPM Uknown platform error during boot time, so I had to also patch it for a full support of graphic card. Thanks.

Hello bpedman, Can you please share your DSDT along with extra folder, I am trying to get my ML booting properly without any success, only option to boot in safe mode with no trackpad support. Or if possible help patch my Vanilla DSDT, which I am attaching. Thanks. dsdt.zip

Hello everyone, I tested the set of files sent by Igashu but got no luck with them. Igashu, can you please let me know the chameleon version you are using? That may help. On a side note, I currently have my system installed using Mountain Lion but I can only start in safe mode, once I try regular boot I get kernel panic. When I boot in safe mode, the keyboard work but not the track pad, I have to use external mouse. I am attaching my DSDT for someone with more experience to take a look at it and, if possible, fix it for me. I can then try to use it with the ML installation to see if it will work. I extracted the DSDT using Ubuntu live CD. Thanks. System: E6520 i7 @ 2.8GHz Intel HD 3000 Nvidia NVS 4200 (1GB) dsdt.zip

Thanks Igashu, I just wanted to mention that my model e6520 with i7-2640M @2.8GHz, with NVS 4200M. I will report back on my results. Cheers!

Hello there, Would you mind sharing your DSDT and extra folder as well as your chameleon version. I have the same machine like and have not been able to make work. Thanks.
