# # Fixing Backlight: Prebuilt

By far the easiest method, all you need to do is download the following file:

- SSDT-PNLF.aml
  (opens new window)
  - For most users
- SSDT-PNLF-CFL.aml
  (opens new window)
  - For Coffee Lake and newer

Main things to note with this method:

- Assumes GPU pathing, works great for 99% of devices but if you're having issues controlling backlight this may be something to look at
- Doesn't really teach you anything
  - For most, this doesn't matter. But to some knowing what makes your hackintosh tick is part of the journey
