BanDia Posted November 25, 2022 Share Posted November 25, 2022 Hello. I've been trying to fix this EFI for over a week now and I'm not getting it. Specifications: Dell Latitude E5440 DualCore Intel Core i5-4300U Intel Haswell 8GB DDR3 Intel HD Graphics 4400 Nvidia Gefroce GT 720M Realtek ALC292 Intel Dual Brand Wireless AC 7260 Intel Ethernet Connection l218-LM What's not working: Graphics acceleration; Internet; Audio; Bluetooth; Brightness control; Fn button. It works: Ethernet; Keyboard and mouse; Trackpad; hdmi. I tried to use some wifi and bluetooth kexts that I found in the dortania guide, but none of them worked. If anyone can tell me what I can do to solve these problems I would be very grateful! I took some prints that maybe can help. EFI.rar Link to comment Share on other sites More sharing options...

BanDia Posted November 26, 2022 Author Share Posted November 26, 2022 Sorry for the delay to answer you. Thank you very much for helping me! It's working now: graphics acceleration Brightness Fn keys Intel Wireless Audio BT I noticed some problems: Trackpad is working like a normal mouse without the gestures (I think I accidentally removed ssdt-xosi); Powering off and Sleep causes it to restart; When I turn it on, a warning appears on the screen saying that I turned off the computer due to a problem.
