HP ELITEBOOK 8770W NVIDIA K3000M HIGH SIERRA Sleep and Backlight Help!


Recommended Posts

Hi and thanks for reading this post!! 


So I have been trying for a few days to install Mac OSX High Sierra on my HP Elitebook 8770w Mobile Workstation, Here are the general specs


Intel core i7 3720QM

Nvidia Quadro K3000m (No Intel Graphics)

128GB Samsung SSD

8GB ram 1600 Mhz


What is working for me:

1.Trackpad and Keyboard

2. Nvidia Graphics without Nvidia web drivers work perfectly, I have installed Cuda Driver

3.Sound IDT working (DSDT Patch layout-id-3 and Apple HDA Patcher)

4.Wifi don't work, I am using USB wifi (Tp-link 725N)

5.Power Management (SSDT) (Only work with SMBIOS Set to iMac13,2 or iMac13,1)

6.Battery Status (DSDT PATCH)


What I am stuck at:

1.Backlight, I don't understand how to get the backlight working. the lcd is detected properly but there is no brightness slider or anything. I have tried the DSDT PNLF patch but it doesn't help me.


 I need some help here to make the backlight work.

2.Sleep (I don't know how to check if I am getting sleep working so some guidance here)


3.Nvidia web drivers give a strange error when I install them at boot. Showing the same error again and again, the laptop does not reboot but it keeps showing an error. I will post a picture when I test again. However the native graphics driver is working fine with proper throttling. 


I am attaching the important files such as my DSDT, IOREG file and config I am using. 


DSDT.dsl (no errors, just 5 warnings)





Any Help would be appreciated. 


-----  UPDATE -----

Since I updated to 10.13.4, I tried again to install the Nvidia web drivers and they are working properly now. However I still don't have brightness slider enabled. 



Anybody willing to help me on the brightness problem??
