We can only give you ideas in this situation. You get too much. Take your time, sit back and check from the beginning.Yes DaveJ1,
For make the base line, so I need do like that with EFI folder. I just don't understand why I follow all check box as Chris111 guide but after reboot still missing CPU power management and can use only internal display (I need do adjustments in Device properties for using 2nd display-external display). I also need add SSDT-PM in ACPI folder to enable CPU PM after that. But no graphics acceleration come out at all.
for post #34, use the boot args and see if you get forward.
