msagres Posted March 27, 2023 Share Posted March 27, 2023 CPU : i5-8350u RAM : 24Go 2400MHZ DDR4 Storage : 1 To Samsung 980 PRO NVME BT/Wi-Fi: BCM94360ng Hello, Thanks to juanpy0223's GitHub repo (https://github.com/juanpy0223/Dell-Latitude-5490-8th-gen), I succeed to install Ventura on my Dell. Everything is working: trackpad(5 buttons), HDMI (also by USB-C), instant screen wake, card reader… But I have a very bad battery life experience. During sleep, it seems to keep consuming the battery, but the fans are off, the screen is black and the system is lock. After a sleep, the battery goes from 100% to 5% in 2 min During wake, the battery can keep the charge at best during 15 min. I tried to clean my EFI, with no success. I don't think it's a hardware issue, the healthiness of the battery is at 89% in the BIOS I hope you can help me with your knowledge to revolve my issue, because it's a good machine running macOS and apart the battery everything is running perfectly. I post my EFI, with different serials numbers if it's can help somebody with others issues. Thanks in advance for your time. EFI.zip Link to comment Share on other sites More sharing options...
BillDH2k Posted March 28, 2023 Share Posted March 28, 2023 I am certain that you have a battery near the end its life. If you don't believe it, try to run Windows 10 to verify it. Link to comment Share on other sites More sharing options...
msagres Posted March 28, 2023 Author Share Posted March 28, 2023 Running Windows, the battery life is normal. It can keep the charge more than 2 hours. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted March 30, 2023 Administrators Share Posted March 30, 2023 Could be result from all those power-related ACPI patches and patched SSDTs you' re using. Can't say I've seen or used them before on my Kaby Lake R/UHD620 Latitude 7490 when I had it. Why don't you try experimenting without those (SSDT-MethodS3-disable, SSDT-PTSWAKTTS and associated ACPI patches on the OC config)? I'm also surprised you run with MBP14,1 SMBIOS for that laptop, rather than MBP15,x. Link to comment Share on other sites More sharing options...
msagres Posted April 7, 2023 Author Share Posted April 7, 2023 Hi, Following yours advices, I edited my config.plist removing the ACPI patches. After some tests, I still have the issue with improvements. Maybe I don't cleaned it enough. EFI.zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted April 7, 2023 Administrators Share Posted April 7, 2023 I'm not familiar with several of those patched SSDT tables you use. All I can suggest is that you compare with setups of other similar 5490 or 7490 posted on the forum. Link to comment Share on other sites More sharing options...
