Thank you for fast replying. i want to patch brightens control. i have a whiskey lake 15-8265U UHD 620. finally i got a clover configuration to spoof whiskey lake as a coffee lake and got Intel UHD 620 GPU waking. but the brightens is 100% i cannot adjust or control. so i tried to get Rehab man patch working. but i couldn't add the patch.

there are no errors in your DSDT

make sure you are using ACPI 6.2a in prefences-> iASL

and don't forget to only edit your DSDT.dsl file

I understand that to apply the patch of brightness i must open my DSDT with IASL, then i click the patch icon and choose the patch of Brightness fix from the left menu then save compiled DSDT.aml? or when i want to apply the last working brightness control fix for Rehabman, i must modify the existing brightness fix patch in the left menu list with the last attached one in the post #12 . Right? If no, Please tel me exactly the steps should i do please. thank you for your assistance and your time.
