@JmW Replace, don't merge.

Check BIOS, see if you have Legacy Option ROMs. If yes, enable it.

Did you use the bootpack I attached above? Because from the screenshot, the version of kexts are different from what I had attached.

You're on an older version of Clover, you could upgrade with this version and add the SMCHelper.efi

Post system's full specs and Clover folder for review Try bootpack here

Since you're using FakeSMC, you should remove VirtualSMC.efi and replace it with SMCHelper.efi

Details are found in developer's guide Scroll Acceleration modes: (v3.8 or later) There are four modes of acceleration for scrolling in my driver, which can be set by editing the plist entry "2FScrollAccelMode" for 2f scroll and "EdgeScrollAccelMode"for Edge scroll. They are: Optimized Acceleration (mode 0) : This is optimized mode which works best across all the touchpads same. Fixed acceleration (mode 1) : This mode has fixed acceleration/speed and varies only with scroll speed value. Extended acceleration (mode 2) : Its an extended version of optimized mode with more acceleration. Super acceleration (mode 3) : This mode reflects the acceleration of your fingers and works based on that. It doesn't depend on scroll speed values from Trackpad prefpane but you can use it extend the speed even more for high resolution touch pads. Super Extended acceleration (mode 4) : This is same as mode 3 but extends the acceleration.

If you're using VirtualSMC.kext, you could pair it with SMCBatteryManager.kext If you're using FakeSMC, then pair it with ACPIBatteryManager.kext

@dujianfei Is your 7280 with HD520 or HD620?

Not seeing any issue with bootpack. There's some error in your kextcache though. Go ahead and remove VoodooPS2Controller from /S/L/E and /L/E. Not necessary, you already have 1 in /E/C/k/Other Repair permission and rebuild cache after.

You can follow my vanilla Catalina guide here including the BIOS settings Once you have Clover installed with the settings provided, add the attached contents to /EFI/Clover This should allow you to install and have a completely working system. Use the same Clover folder from the Installer for the installed drive when finished. Latitude 3400 Catalina.zip

what app is that you're using? I use Clover Configurator

Means it's not detecting the installer half way through. Make sure you have set in BIOS UEFI / AHCI Make sure you have either HFSPlus.efi or VBoxHFS.efi in /E/C/drivers/UEFI Lastly, you might need to have USBInjectall.kext + Port Limit patch

What's the model of this laptop?

Reboot with the Installer. At the GUI, choose "install MacOS Catalina from <HDD name>" Why use Distro Niresh? If you already have a working system, you can download Catalina from App Store and create a vanilla installer.

Give this a try. Add to /E/C/A/Patched. You might have to add it to the Config file under SSDT sorted order SSDT-Disable-DGPU.aml.zip

You mean the verbose mode? Once you have it running perfectly you can edit the Config file with Clover Configurator to remove the boot arg -v

1) No network connection is necessary unless your installer if for Recovery and not offline. 2) Make sure your drive is formatted to GUID / Journal Extended. If you installed Windows first, it might be set to MBR and the EFI partition is too small. MacOS requires 200MB/ Windows default size is smaller. Better to install MacOS first with drive formatted to GUID, partition the drive for Windows. Windows install on GUID perfectly fine.

the latest Firmware suppose to fix the issue, but all the info I found is for older MacOS, not Catalina. Similar issue to Samsung PM981.

Post it for others to test. Do you have battery and brightness issue as the OP have?

Try this bootpack

Try this, replace into /EFI/Clover E5470_Catalina.zip

Upgrade Clover to latest v5103 Update Lilu.kex and Whatevergreen.kext to latest Get rid of GenericUSBXHCI.kext, no use after Yosemite Replace ACPIBatteryManager.kext with SMCBatteryManager.kext since you're using VirtualSMC. ACPIBatteryManager.kext is paired with FakeSMC.kext. Not sure if sleep and wake works with VoodooHDA, if not, then replace it with AppleALC.kext and use layout-id = 12

post debug file

that's what you posted on the 1st post. Also in drivers64UEFI, remove EmuVariableUefi-64.efi and only keep AptioMemoryFix-64.efi or vice versa, not both.
