HP Elitebook 840 G2
I5-5300u Broadwell-u HD5500
Docking station - HP ULTRASLIM 2013 D9Y32AA
Displayport does not work on the docking station.
After connecting the displayport, the screen blinks a few times and nothing more.
I need to buy Macbook Air unless I have peace of mind.
I set the ig-platform, it succeeded.
I put it to sleep a few times, unfortunately, a black screen. Time is precious and there are no solutions.
Thank you for your help.
I deleted /APCI/Patched/SSDT-IGPU.AML
In config.plist via xcode I set Graphic IG-PLATFORM to 0x16060000. Now everything is fine when waking up and waking up. But my laptop screen is terribly dark. The lighter / darker button does not work.
How can I solve this?
