E5430 Almost There

Recommended Posts

Dell E5430

Intel i7-3520M

8GB Ram

Bios A18

Greetings.. Installation of 10.13.6 High Sierra is successful using Jake's Efi https://osxlatitude.com/applications/core/interface/file/attachment.php?id=18876, however 1 issue currently exists... every 30 seconds display goes to a black screen and system sleeps. I can wake it up with a key strike, but only lasts for 30sec before problem repeats. I have generated a patched SSDT for my cpu, and am using the DSDT in the EFI file. Any assistance would be greatly appreciated, thank you!

Thanks so much, Jake.. I've attempted to do that, however the screen shuts off, and the debug is interrupted during the process. Incidentally, every time I key click to get a display, it forces me to log in.. If I don't press a key, the laptop goes into sleep mode.
