What isn't working is the 2nd battery, bluetooth and the camera. I have seen issues in the past where some people with a different hard drive will struggle and so if that's you then I am sorry. Use the Installer EFI with your USB pen drive and the Post Install EFI on your Hard Drive when installation is complete.  You will need to full delete your laptop hdd and start fresh.  NEW EFI - https://drive.google.com/file/d/1AJKYdHIYE_moF4J9cQtmgGVh8chxgL57/view?usp=sharing Okay so I was having some overheating issues on the base of the laptop and so I ran ACPIExtractAll and have applied them in this EFI. This has fixed all my issues, however if your laptop is different you may want to use the Post Install EFI at the top and then get your own ACPI tables, but you're welcome to use mine.  Good Luck Edited October 28, 2023 by MetalChris87 2 Quote Link to comment Share on other sites More sharing options...

Phong Nguyen Hong Posted January 13 Share Posted January 13 Using these EFIs, my 15" SB3 has only 26 MB VRAM. How to fix it? Quote Link to comment Share on other sites More sharing options...
