• edit ssdt.dsl if needed

Build the DSDT patch

sudo cp -f ssdt.aml /boot

Copy grub script and make it executable

sudo cp -f 01_acpi /etc/grub.d

sudo chmod +x /etc/grub.d/01_acpi

Update grub config

sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

OR

sudo grub2-mkconfig -o /boot/grub2/grub.cfg

May also need to disable secure boot. (I had to in Fedora)

Reboot and enjoy
