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 ;-)

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.
