@ all Give this a try EFI.zip

Has it ever work with your files?

You need to enable specific Quirks similar to the Opencore guide for specific cpu class.

follow this screenshot except change framebuffer-con1-alldata = 02050000 00040000 07040000 03040000 00040000 81000000 04060000 00040000 81000000 to 02050000 00080000 07040000 03040000 00040000 81000000 04060000 00040000 81000000 // <- for HDMI connection

Give this a try. Have a backup bootable USB or place EFI in USB and boot with USB. If works, then replace into installed drive's EFI Note: Rename folder to EFI EFI-E5440_OC0.7.1.zip

You'll need to upgrade Clover to the latest and there are big changes since it added OpenCore drivers to support Big Sur.

Yes, added the Fn patch Does it work?

replace with this DSDT DSDT.aml.zip

@lamatta17 Try different layout-id for sound / microphone 13, 14, 16, 21, 56 Reset NVRam each time when you switch the layout-id Post IOReg file with IORegistryExplorer.app with version 2.1, not 3.0+ For further assistance

Just add the hot patch to your Config file, no need to replace any kext.

You can't boot from a dmg file. You can restore the DMG to USB

Make sure you set BIOS to: UEFI and enable AHCI RAID won't work i that's what you have and Secure Boot disabled

Try my OpenCore files here

Try resetting NVRam or update to latest kexts

Looks like NVMe.kext fixed power management for your NVMe drive as well.

Yeah according to your previous IOReg file, power management was not working, but should be working now. Post new IOReg file

Just press the spacebar to review the options Change HideAuxiliary to No if you prefer it showing all the time

Simple fix. Under kernel / Add / NVMeFix.kext, add a string call Arch. You can just copy it from the other

Try this EFI folder Upgraded to OC 0.7.1 with latest kexts EFI.zip

Compress the video and attach it here Does your system have a discrete graphics card? if so, it might need to be disabled via SSDT patching. Post an IOReg file for better troubleshooting using IORegistryExplore.app v2.1, not 3.0+

You should charge it to 100% Then let it drain completely before charging again https://accatech.com/calibrate-dell-laptop-battery/ By the way, your Config file under ACPI/Add does not correspond to the SSDT's you have in the ACPI folder. i.e. missing SSDT-ALS0.aml, SSDT-DATA.aml, and SSDT-SBUS-MCHC.aml just to name a few. Not sure how your system can boot successfully and not get an error message Also I don't think this model has an I2C touchpad, so having voodooI2C is useless. Unless you have a touchscreen, even then, I believe that would be USB based.

With Olarila's boot disk, make sure you replace the EFI with quynkk5's EFI

Try replacing with this Config file to your EFI folder Your files already has the SSDT to disable the dGPU config.plist.zip

You can start by listing the full system specs, best to add it to your signature so no need to go back to 1st post each time to check.
