[Guide] Laptop backlight control using AppleBacklightFixup.kext

how to know and check I have IGPU PWM or not
Click to expand...

If AppleBacklight.kext or IntelBacklight.kext (with Brightness by bergdesign or <10.12.3) don't work, then your computer does not use the IGPU PWM for backlight.

It is pretty typical for Fujitsu of your laptop era (and Samsung, and certain Lenovo).
 
thanks sir for answer
 
Good day,
I followed the guide correctly. Just before rebuilding the cache, I restart the computer and the brightness works, at this time I rebuild the cache and restart it again. Then the brightness does not work anymore.
Any ideas?
I leave the clover registration and config.plist
Note: i use kext wizard
I'm sorry if my English is bad
Thank you!

"Problem Reporting" files are incomplete.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something.

Problems:
- config.plist/SystemParameters/InjectKexts is set to true. Should be "Detect"
- try with attached SSDT-PNLF.aml
