Install IntelBacklight and patch DSDT or Clover with PNLF method

thanks for your prompt response, but I still can't make the brightness work.

 

I mod the bios setting for the graphic issue to do the installtion.

 

and here is my config.plist

I installed the inteBacklight.kext to \L\E, and \S\L\E folder and repair the permission.

 

I saw there is a PNLF setting in my config.plist, and I don't know if my DSDT has patched or not, because I download my DSDT from web to get my audio/battery work.

 

thanks

config.plist.zip

Only install a kext ONCE. Either in /L/E or in /S/L/E but not in both.

 

ok, I removed the one in /S/L/E, repair permission, and reboot, still no brightness.

 

 

 

Did you use bootpack and fixed battery DSDT from here?

NO, I can't get to the installation screen, always CPU panic.

 

so I found this CLOVER folder and i can do the installation, https://osxlatitude.com/index.php?/topic/9165-cant-dump-bios-inspiron-5548/?p=61697 (post# 10)

 

 

here is the screen shot when I boot with -V,
