    Dell 9020 i5 keeb restart can't reboot

    Did you place the Kexts and DSDT into the right directory?

    You need to remove the PCIe card if it has one. Only use the onboard video card and must use DisplayPort connection.

    Boot with 

    -v -f -no-zp GraphicsEnabler=Yes IntelAzulFB=10

     

    If you want to use the Sapphire HD 6450 card, try this bootflag

    -v -f -no-zp GraphicsEnabler=Yes AtiConfig=Pithecia

    Welcome bigdog1,

     

    KP with the message "AppleIntelCPUPowerManagement.kext" is associated with power management. You need to generate a new SSDT for your specific CPU as the one included is for a different CPU. You need the DSDT to enable graphics and audio.

    Now, I'm not sure you're following the NVS guide or the Optimus guide. With NVS, you should have HDMI video and audio but lack sleep. You'll just get a blank screen on wake.

    With the Optimus guide, the nvidia card is disabled and you'll gain sleep capability with the HD 4000, but loses HDMI as its linked to the nvidia chip.

    If you prefer the nvidia graphics, then install NullCPUPowermanagement.kext, this should prevent the KP as mentioned.

    Okay, make a copy of your files before replacing with the attached.

    • Place DSDT/SSDT-7 to /Clover/ACPI/Patched
    • Run ssdtPRGen.sh from terminal to generate SSDT for your CPU and place in same folder
    • Replace Config to /Clover
    • Place the 2 kext in /Clover/Kexts/10.10 or Other, which ever folder you are using
    • Install the kexts in SLE to /System/Library/Extensions
    • then repair permission and cache with following command in terminal

     

    sudo chmod -Rf 755 /S*/L*/E*
    sudo chown -Rf 0:0 /S*/L*/E*
    sudo touch -f /S*/L*/E*
    sudo kextcache -Boot -U /
     
    If you have install any other audio kext, remove remove and restore to the vanilla kexts.

    It's a known issue due to EAPD in Realtek devices. The codecCommander.kext included in the bootpack suppose to have fix the issue. 

    It works on my E7440 but I have installed the kext to /Library/Extensions instead. I don't know if it'll make a difference.

    Just move the 2 kexts from /S/L/E to /L/E and run the permission fix below

    CodecCommander and AppleHDA_ALC292

     

    sudo chmod -Rf 755 /L*/E*

    sudo chown -Rf 0:0 /L*/E*
    sudo chmod -Rf 755 /S*/L*/E*
    sudo chown -Rf 0:0 /S*/L*/E*
    sudo touch -f /L*/E*
    sudo touch -f /S*/L*/E*
    sudo kextcache -Boot -U /
