It does not work with enabled legacy boot and/or implemented backlight control either...

Attach ioreg as ZIP: http://www.tonymacx86.com/audio/58368-guide-how-make-copy-ioreg.html. Please, use the IORegistryExplorer v2.1 attached to the post! DO NOT reply with an ioreg from any other version of IORegistryExplorer.app.

Provide output (in Terminal):
Code:
kextstat|grep -y acpiplat
kextstat|grep -y appleintelcpu
kextstat|grep -y applelpc
kextstat|grep -y applehda

Attach EFI/Clover folder as ZIP (press F4 at main Clover screen before collecting). Please eliminate 'themes' directory. Provide only EFI/Clover, not the entire EFI folder.

Attach output of (in Terminal):
Code:
sudo touch /System/Library/Extensions && sudo kextcache -u /

Compress all files as ZIP. Do not use external links. Attach all files using site attachments only.

Comments:
- backlight control is not implemented
- CPU PM is not implemented
- ACPI is not patched
- ioreg shows both displays detected, edid looks ok, so it is probably a backlight related issue...

Implement backlight control.
 
Uff this laptop :crazy::crazy::banghead:...
I patched everything like you said but still it boots but my internal display doesn't work...
I attached EFI/CLOVER & a copy of ioreg
