  1. Edited the 15/07/2014 Hi all ! After months of passive research i have found on some different forums a DSDT solution for disabling the NVidia card. Disabling Nvidia allow to save battery power of 2x and temperature of laptop too. My Specs Acer Aspire V3-571G-73614G50Makk :: Processor Intel Core i7-3610QM 2.3 GHz (Intel Core i7) :: Mainboard Intel HM77 (Panther Point) :: Memory 4096 MB :: Graphics adapter NVIDIA GeForce GT 640M - 2048 MB, Core: 708 MHz, Memory: 900 MHz, DDR3,, Optimus :: Display 15.6 inch 16:9, 1366x768 pixel, LG Philips LP156WH4-TLA1, TFT LED :: Soundcard Realtek ALC269 @ Intel Panther Point PCH - High Definition Audio Controller :: Networking Broadcom NetLink BCM57785 PCI-E Gigabit Ethernet Controller (10/100/1000MBit), Atheros AR5BWB222 Wireless Network Adapter (b g n ), 4.0 Bluetooth :: Optical drive MAT{censored}A DVD-RAM UJ8B0AW :: Hackintosh Config SMBios : Macmini6,2 org.chameleon.boot.plist : link DSDT : link Extra Folder : link Source DSDT/SSDT Method ( work on it, not fully fonctionnal ) : Link here DSDT Method (work with all bootloader) Instructions Needed AIDA64 version 2.80 --> link ssdtPRGen.sh --> link AppleIntelCPUPowerManagementInfo.kext --> link MacIASL --> link Disabling NVidia card In the first step, dump your dsdt from Windows with AIDA64 (version 2.80 max) --> tuto YouTube Reboot on OSX This patch don't need to extract or modify any SSDT. You can see the DSDT edits in the link of qwerty12 topic in credits. Quickly, in DSDT, i call external method for disabling the card. These links calls methods of SSDT-4 in my config but can be different with your machine. You don't need to copy manually the _OFF method from SSDT to DSDT. Add these lines if you don't have them to the top of your DSDT : [...] External (_SB_.PCI0.PEG0.PEGP._PS3, MethodObj) External (_SB_.PCI0.PEG0.PEGP._PS0, MethodObj) External (_SB_.PCI0.PEG0.PEGP._OFF, MethodObj) External (_SB_.PCI0.PEG0.PEGP._ON, MethodObj) External (_SB_.PCI0.PEG0.PEGP.SGOF, MethodObj) External (_SB_.PCI0.PEG0.PEGP.SGON, MethodObj) [...] I added the method M_OF before the _WAK method : [...] Method (M_OF, 0, NotSerialized) { If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._OFF)) { \_SB_.PCI0.PEG0.PEGP._OFF() } If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._PS3)) { \_SB_.PCI0.PEG0.PEGP._PS3() } If (CondRefOf(\_SB_.PCI0.PEG0.PEGP.SGOF)) { \_SB_.PCI0.PEG0.PEGP.SGOF() } ​ } [...] After that, i call the M_OF method in _WAK : [...] Method (_WAK, 1, Serialized) { M_OF () If (LAnd (LEqual (\_SB.PCI0.LPCB.EC0.AAST, One), LEqual (\_SB.PCI0.LPCB.EC0.AAEN, One))) { Store (Zero, GP53) [...] And i call the M_OF method in the _INI method : [...] Method (_INI, 0, NotSerialized) { Store (0x07D0, OSYS) M_OF () If (CondRefOf (\_OSI, Local0)) { If (_OSI ("Windows 2001")) [...] If you use Chameleon or branch, paste your modified DSDT to your Extra folder and add these options to your org.chameleon.Boot.plist : <key>DSDT</key> <string>/Extra/DSDT.aml</string> <key>DropSSDT</key> <string>No</string> If you use Clover Bootloader, copy DSDT file in "EFI/CLOVER/ACPI/Patched" Reboot and go to Applications/Utilities/System Information Go to Graphics Card Section, if the NVidia Chipset not appear, it’s working. Enable the SpeedStep management The only problem with this technic is the Power Management. When your turn off the DropSSDT flags in org.chameleon.Boot.plist, Chameleon don’t go dump your SSDT tables in the ACPI tables of your machine. For enabling SpeedStepper with that fix, you should make a patched SSDT with the ssdtPRGen method : Download the later ssdtPRGen.sh Be sure that your SMBios.plist is appropriate with your CPU and system (A good SMBios can fix the iMessage, iCloud, iTunes and Apple Store connexion and login bugs). With my V3-571G core i7, i prefer the Macmini6,2 model for more speed steps. In Terminal app, launch the ssdtPRGen.sh with command : sudo sh /the_way_of_your_file/ssdtPRGen.sh Write your password and type "y" when it’s demanded for make a ssdt_pr.aml in your Extra folder only if you use Chameleon bootloader. If you use clover, copy this file in "EFI/CLOVER/ACPI/Patched" and rename it to ssdt-1.aml. If you have already a ssdt-1, rename it to ssdt-2... Reboot To be sure that your Speed Stepper is patched, download the AppleIntelCPUPowerManagementInfo.kext and add it to your System/Library/Extensions/ folder with the kext installer of your choice. I for one better in Kext Utility. Rebuild cache with the app of your choice (kext utility make that automaticly) and reboot. At start, open your terminal app and type this command : cat /var/log/system.log | grep "AICPUPMI:" If you can see a lot of P-States, you did a good job. About problems Problem with auto ON after sleep Past this method before the M_OF method in your DSDT : Method (M_ON, 0, NotSerialized) { If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._ON)) { \_SB_.PCI0.PEG0.PEGP._ON() } If (CondRefOf(\_SB_.PCI0.PEG0.PEGP._PS0)) { \_SB_.PCI0.PEG0.PEGP._PS0() } If (CondRefOf(\_SB_.PCI0.PEG0.PEGP.SGON)) { \_SB_.PCI0.PEG0.PEGP.SGON() } ​ } After that, call M_ON method in _PTS (Prepare To Sleep) so that the _WAK after sleep can shutdown the card.

  3. First and foremost, I want to thank fusion71au for his assistance with getting my system up and running with Mavericks. My system Vostro 1700 – Intel Core 2 Duo T7250 – 4GB DDR2 667 RAM – Nvidia Geforce 8600M GT – HP rebranded to Apple Airport BCM94322MC – IOGear Bluetooth 2.1 USB – Sigmatel Stac9205 Audio – 17 inch 1440x900 Glossy Screen Of course, make adjustments for your system as necessary. I have no instructions for the DSDT patching because fusion71au did the patching for me. Also, if you need to do the rebranding of your wireless card, there are plenty of resources on the net that can help you out. For the Post Installation, I did all the work from within my Mountain Lion installation on a separate hard drive, you might be able to boot from the installer drive to do the work, but I didn’t bother trying as I had issues in the past and it was just easier to do it from a running system. Instead of making a kext package, I’m providing links to give proper credit for others finding or modifying kexts to work with specific devices. Only use the Kexts that I list in the guide, there are others in the packages that are not needed.

    HP ZBook 15 Graphics Problem

    Hello, I have a new HP ZBook 15 with Intel I7 4700MQ, 32 Gigs Ram and a Quadro K2100M graphics Adapter with 2 Gigs VRAM, I succesfully installed Niresh with Clover on it and updated to 10.9.4. The only problem I have is that graphics don't really work. Booting normally no drivers load, so I am without acceleration and in 1024x768... The Graphics Adapter is shown as a HP Quadro K2100M with 3 Megs Vram... close... When I boot with NVDA_DRV=1, the NVDAGK100HAL kext loads during boot, but the the bootprocess stops afterwards. Sometimes the PCIPlatform loads before and sometimes after this kext... with same results. If I hit keys The sound works, and the hdd shows some activity. Does anyone have an idea how to go on? I already tried to inject a Quadro K2100M vbios and my correct EDID via Clover Configurator. But it does not change anything. I already tried an external screen connected via Displayport but this also did not change a thing. The internal Display is also connected via Displayport. How are NVCAP Values generated for Displayport setups?
