if that fixes your boot issue, then it's good.

all those ssdt are integrated into SSDT-840G3.aml or implemented in the config file or replace with kexts. the ssdt is significantly reduced due to removal of battery patches, now using ECEnabler.kext only.

look under card reader, not PCI, that's just for cosmetics only.

Give this a try, assuming you have Intel wifi/BT for Big and Monterey Lenovo P50 OC 0.8.1.zip

the xprw is to fix sleep issue try this one config.plist.zip

@cuti_it @Baio77 it has an SMBus touchpad. Keep the existing voodoops2 use this config to enable the touchpad config.plist.zip

try this, made a few mod to your config fileconfig.plist.zip

your ioreg file seems to be corrupted remove AppleSDXCInjector.kext and VoodooSDHC.kext

Airdrop is not supported for Intel https://openintelwireless.github.io/itlwm/FAQ.html#features

What's the model of your Wifi / BT combo? You have both Intel and Broadcom kexts for Wifi, but only Broadcom BT kexts. If you have Intel combo, then remove all the Broadcom kexts and add the Intel BT kext: IntelBluetoothFirmware.kext Post IOReg file

Please post full system specs, EFI folder you're using and IOReg file for IOReg file, use IORegistryExplorer.app version 2.1...google it.

Apple prohibit sign means it's not detecting your drive which mean it's an USB port issue. have you tried on different ports? What model drive does it have? Certain NVMe drives are not compatible like Samsung PM981, PM981a...etc

Just enable UEFI / AHCI Disable secure boot

try files from this thread and update the files with fix from 2 posts down https://osxlatitude.com/forums/topic/14452-success-latitude-5300-up-and-running/

Samsung PM981, PM981A and PM998 are known not compatible in MacOS, doesn't matter on a Hack or real Mac.

Post IOReg file using IORegistryExplorer.app v2.1

when you delete CPUFriendDataProvider.kext, you need to remove it from the config file too

Did a validation check on your Config and found some errors. Here's a fixed one, give it a try Some kexts are in the wrong orders and had to be corrected. The CPUFriendDataProvider.kext, is that specifically generated for your CPU? It's for power management, leave it out if you're also using ssdt-Plug, one or the other, not both but I didn't make that change. config.plist.zip

@adamshahcatalyst1 @AMIR CH Try files from here, which is what the OP was using https://osxlatitude.com/forums/topic/17228-7490-update-from-big-sur-to-monterey/?do=findComment&comment=114426

take a look at Allan's guide here Maybe add NVMeFixup.kext for power management for the NVMe drives you have on the system.

Please post full system specs A copy of the EFI folder and IOreg file using IORegistryExplorer.app v2.1

@Mattia27c The latest version works fine on my E7470 with v8. Yes it does go crazy from time to time but not often. I only use it for scrolling, swiping, zoom in and out. 3 fingers won't work well, that might be your issue with the random movement, don't use it. There is a second delay perhaps from keyboard to touchpad. Hardly notice it though.

If you look in the BIOS, it should show 92HD93 as Hervé posted above. Post IOReg file using IORegistryExplorer.app version 2.1. You can google it. Might be an IRQ conflict. Follow here to generate the patches using SSDTTime

the config look fine. Layout-id is added correctly did you test for audio?

I think I found my issue. The rename of EH01 and EH02, the value of Count should equal 0, not 1. Anyway with your new files, all looks good. You just have to decide whether to use ssdt-plug.aml or ssdt.aml. Both are for power management. SSDT.aml is hardcoded for i7-4810MQ. If your cpu is the same, then you could keep it instead of ssdt-plug.aml. SDCard reader is working, brightness control looks good. AMD disabled, so that should extend battery life.
