[SOLVED] E7250 High Sierra - Built it screen issues

Recommended Posts

Hello everybody!

I have a Dell Latitude E7250. I managed to install High Sierra 10.13.2 (I will upgrade to 10.13.6 soon)

 

Everything is fine (WIFI no, but I know the reason). I have an issue with the laptop built-in screen. Most of the time that I switch on my laptop it doesn't work. It stays off. It's not detected by the OS. Sometimes (I don't know the reason) it works perfectly. 

Issue was during installation too.

During boot it works perfectly, when the apple appears the screen goes off

External HDMI display is always perfectly detected and 100% working.


I can't attach any file because I don't have enough space left.
Efi.zip is linked in my owncloud: https://owncloud.highlight.com/index.php/s/eWty68GIBxzL8j1

Inside you will find my ORIGIN files that I extracted with F4

 

Thanks in advance

Bootpack installed

after first reboot: stucked on LEGACY SHIM

after rebooting again it started...same problem with the black screen (closing and opening the lid it works) but now it keeps the brightness (it was always at 20% after reboot, now kept 100%)

While I was replying to this post I got a kernel panic:

  Reveal hidden contents

 

now restarted and it is working

What can I do now?

You didn't use the files I linked above, goes into /EFI/Clover. Replace, not merge

Also install latest Clover with the following settings:

  • Install for UEFI booting only
  • Install Clover in the ESP
  • Drivers64UEFI\AppleImageCodec-64
  • Drivers64UEFI\AppleKeyAggregator-64
  • Drivers64UEFI\AppleUITheme-64
  • Drivers64UEFI\DataHubDxe-64
  • Drivers64UEFI\FirmwareVolume-64
  • Drivers64UEFI\FSInject-64
  • Drivers64UEFI\SMCHelper-64
  • Drivers64UEFI\ApfsDriverLoader-64
  • Drivers64UEFI\AptioMemoryFix-64
  • Drivers64UEFI\PartitionDxe-64
  • Install Clover Preference Pane 

Finally add to Drivers64UEFI\HFSPlus.efi (not included in Clover installer)
