Can you post new debug file?

give this a try. Updated OpenCore file and Config Inspiron 7577 BS.zip

Looks like there's issue with your USB ports. Get rid of SSDT-UIAC.aml Replace Config file config.plist.zip

Does the files currently run Catalina or Mojave? Post KP screenshot

We can add the GUI boot later once you're up and running. For now, to add that boot arg, you need to open Config file with Xcode or PlistEdit Pro, go down to NVRam/Add/7C436110-AB2A-4BBB-A880-FE41995C9F82/boot-args and add it to the end the string.

What patches did you apply to the DSDT?

Use latest AirportBrcmFixup Make sure to enable the injectors AirPortBrcmNIC_Injector.kext, then AirportBrcmFixup. You could leave AirPortBrcm4360_Injector.kext off or set the Maxkernel to 19.9.9 if you have multiple MacOS running. AirportBrcmFixup.kext.zip

No, shouldn't take that long. Try adding to boot arg -igfxvesa

I see you already have ssdtpr generated SSDT-PM.aml, so not needed. So what's the issue?

Just enable AppleCpuPmCfgLock & AppleXcpmCfgLock in Kernel Quirks Add SSDT-PLUG.aml for power management

How long did you let it sit?

Change Count from 1 to 0

Your other thread shows you have it running, what changed?

Try changing the change Method (GPRW,2,N) to XPRW, pair with SSDT-GPRW.aml patch Count from 1 to 0

Just noticed you don't have an USBPorts.kext, SSDT-UAIC.aml or USBInjectall.kext. Re-upload new files above.

The kext is for an Alps touchpad by 1Revenger1. I just made 2 changes the the keyboard and trackpad kext renaming com.apple.iokit.IOHIDSystem to com.apple.iokit.IOHIDFamily. Check your Battery status is working, if that's working, then the touchpad preference should be enable. From your bootpack, looks like you're using an old version of ACPIBatteryManager, try replacing it with SMCBatteryManager. Attached version works for BS. SMCBatteryManager.kext.zip

I'm not familiar with Chris1111's installer but do remember Pokenuygen has a Probook Installer back in the days. I did the build the vanilla way, using createinstallmedia command to create the installer and adding the EFI OpenCore boot files files. Hotpatched SSDT are based mainly from Rehabman's GitHub. There's a strange issue where the internal drive is not detected by Big Sur but no issue with Catalina and below using the same files. A member in Insanelymac also had this very same issue who also has an HP. He has a newer model that has an I2C touchpad, so in adding support for the touchpad, he discovered that it also enabled the Internal drive to be detected by Big Sur. So even though the Elitebook 840 G3 doesn't have an I2C touchpad, enabling that driver does indeed enable the Internal drives to be detected by Big Sur...I'm still scratching my head around that but hey, as long as it works. Currently the TrackPoint is not working, touchpad works just fine with Rehabman's voodoops2Controller, but no multitouch gestures. I'm currently looking at this new kext call VoodooSMBus + VoodooRMI, that's suppose to give better support. This model is suppose to be supported according to the description. We'll see how it goes.

run this log show --style syslog | fgrep "Wake reason"

Disable wake on WLAN/WWAN/LAN in the BIOS

Success: HP840 G3 with DW1830 Works: Sleep / Wake SD card reader Internal speaker / Headphone Keyboard / Touchpad Ethernet / Wifi (replaced with DW1830) DP video / Audio USB 3.0 Ports Multi touch gestures VGA (not tested, don't care for it)

Replace with these folders to EFI folder 3070 BS Ready.zip

You found a working voodooPS2 kext for BS? Where?

Here you go E5450_BS_Ready.zip

Try this one VoodooPS2Controller-Alps.kext.zip

Awesome, enjoy.
