filbip Posted September 3, 2015 Author Share Posted September 3, 2015 If your LCD is 1366x768, your Graphics key in config.plist should scecify that it is not a "dual link" : <key>Graphics</key> <dict> <key>Inject</key> <dict> <key>ATI</key> <false/> <key>Intel</key> <true/> <key>NVidia</key> <false/> <key>DualLink</key> <integer>0</integer> </dict> </dict> Sound should work if the patched AppleHDA.kext is installed in /S/L/E. Battery management should work too with the ACPIBatteryManager.kext from post #1 on S/L/E. Copy the kexts to /System/Library/Extensions/ and hit the following commands :. cd /System/Library/Extensions/ sudo chown -R 0:0 AppleHDA.kext ACPIBatteryManager.kext sudo chmod -R 755 AppleHDA.kext ACPIBatteryManager.kext sudo touch /System/Library/Extensions sudo reboot Sound and battery icons should appear in menubar 1 Link to comment Share on other sites More sharing options...

filbip Posted October 20, 2015 Author Share Posted October 20, 2015 Hi, unfortunately, now I have no E5520 for testing. Perhaps you tried different EFI folders from different sources. Be careful to not have a config.plist under EFI/CLOVER/ if you use the OEM folder (EFI/CLOVER/OEM/Latitude E5520/). It could be easier to copy config.plist and kext folder from EFI/CLOVER/OEM/Latitude E5520/ to EFI/CLOVER/ and rename OEM to OEM.OLD to be sure to use only /EFI/CLOVER/ . All E5520 can boot with UEFI or legacy BIOS. It is a "bios" setup. For beginning, it is easier to use BIOS with the EFI folder on your system root.
