pong1234 Posted July 13, 2020 Share Posted July 13, 2020 Everything is working fine on my dell e7440 except sleep and battery %. The computer sleeps alright but mostly wakes up to a dark screen. I have tried darkwake=0,1 and no bootflag, nothing worked. The other thing is that the battery % doesnt update automatically. I have to manually refresh it. Can anyone please have a look at my efi and suggest any changes. Thanks a lot. pls hellp. EFI.zip Quote Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted July 13, 2020 Administrators Share Posted July 13, 2020 what exactly is a dark screen mean? like nothing or there is something displaying but the back light is not on or its very dim? if that is the case of it being back light then you probably need to get your nvram working properly.

morpheousman Posted July 15, 2020 Share Posted July 15, 2020 AppleBacklightFixup is not needed anymore when using Whatevergreen. Looks like you are missing some hot patches as well. Try using Jake Lo's E7440 bootpack. It has my e7440 is running smooth. Quote Link to comment Share on other sites More sharing options...

Administrators Hervé Posted July 15, 2020 Administrators Share Posted July 15, 2020 You simply download that pack and overwrite your ACPI + kexts folders + config file by the downloaded ones. Quote Link to comment Share on other sites More sharing options...
