[...] How do you check if your soup is hot? Here's a hint: your SysProfiler and https://osxlatitude.com/index.php?/topic/8431-ssd-benchmark-results/ Link to comment Share on other sites More sharing options...
mrdr Posted January 27, 2017 Author Share Posted January 27, 2017 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 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 27, 2017 Administrators Share Posted January 27, 2017 Only install a kext ONCE. Either in /L/E or in /S/L/E but not in both. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 27, 2017 Moderators Share Posted January 27, 2017 Did you use bootpack and fixed battery DSDT from here? Link to comment Share on other sites More sharing options...
mrdr Posted January 27, 2017 Author Share Posted January 27, 2017 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, Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 27, 2017 Administrators Share Posted January 27, 2017 Maybe your DSDT has no PNLF device defined. Try and add one as explained here. Link to comment Share on other sites More sharing options...
mrdr Posted January 27, 2017 Author Share Posted January 27, 2017 it already applied in the config.plist, do i still need to do it in DSDT? <key>ACPI</key><dict><key>DSDT</key><dict><key>Debug</key><false/><key>DropOEM_DSM</key><false/><key>Fixes</key><dict><key>AddPNLF_1000000</key><true/></dict><key>Name</key><string>DSDT.aml</string><key>ReuseFFFF</key><false/></dict> Link to comment Share on other sites More sharing options...
