kormoran Posted November 13, 2019 Share Posted November 13, 2019 Hi, i have laptop as listed in title: 4702HQ, 16GB RAM, Bios A11. I have issue - after wakeup from sleep screen remains dark (there is no backlight) but laptop works (i hear music, mouse click sound etc). Before update to catalina, on High Sierra/Mojave all works ok. Do you have any solutions for it? On forums peoples write to disable com ports but in this laptop there is no serial port. Also i remove all installed additional kext in library/extensions, cleared cache but no effects. Best regards. Kext lists loaded in clove and config.plist attached. config.plist.zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted November 13, 2019 Administrators Share Posted November 13, 2019 Did you disable hibernation after upgrading to Catalina? If you did not, please refer to our FAQ section. Link to comment Share on other sites More sharing options...
kormoran Posted November 13, 2019 Author Share Posted November 13, 2019 Yes, of course. Screen. Also include debug generated just after reboot. I use config from Clover/OEM/Dell Precision M3800 debug_17386.zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted November 13, 2019 Administrators Share Posted November 13, 2019 Then you may try and experiment with darkwake boot arg. Link to comment Share on other sites More sharing options...

Also try to don't load any kext except fakesmc, lilu, whatevergreen and usbincjectall. Also there is black screen after wake up from sleep (i disable hibernation before test).
