Hi RehabMan i have been following this thread for some time, been installin osx on HP notebooks to fellow friends (musicians and video makers in Milan) since january. I solved most issues by reading this thread or just waiting for your updates, and also i could report a lot of ssues i had expecially with audio coming and going random (but it seems like you fixed this during summer, being running great this week). The reason i am now posting on the thread is a more serious issue that i stumbled upon yesterday: the elitebook 840 g1 bios starting from 1.39 (late 2016 update) gives serious glitches with the internal screen.
In june i hacked the first 840 g1 and was super satisfied with the result, also because the audio was ust as stable as the old 6570b i made (while the 840 G2 and 820 G2 i had made previously all had random audio not orking at boot, no metter the ssdt layout changes so i had to run voodoohda). The laptop had a i5 4310U and an AMD RADEON HD8750. So when i came back from holidays i bought one for myself from the same supplier (identical model). I run the whole install process but the screen has some major glitches, like scrambling all the time. I called back my friend and copied the bios setting from there without any result (memory size, Hybrid Graphics Enhanched Feature, everything). I then proceded to swap the SSDs, maybe it was some late update to your github, but no avail (also quick note: now the audio jack is working with the latest code; that prompted me to reinstall from scratch on the 840 g2 i made for my sister, that is now working stable without Voodoo HDA!). No change: the new 840 with the old ssd (installed in june) still glitches, the old 840 with the new code does not.
I finaly nailed the issue with the bios revision installed n the notebook, the old working one has 1.37 while the new had 1.39. I tried to roll back the bios but the notebook would not allow that, so i proceeded to update to 1.40 (released this summer) but the problem is now even worst.
The problem is not happeing on windows or Linux. I tried EC reset an tried to upgrade graphic drivers on windows. I tried different ram configurations (swapped with the old ram also). What are your suggestions?
I also found out that the new code has a issue i found also on an Acer Aspire Nitro with HD 4600, that is slow mouse pointer after login or resume from sleep, an issue not found in the code from june (so the old ssd has glitched but mouse was responsive and audio jac was not orking, even on the new bios note).
