E6440 Catalina : Freeze after wake up from sleep

Recommended Posts

Dear all, 

 

I have installed Catalina on Dell E6440 with integrated intel hd4600, it works quite well except the following:-

 - Laptop freezes few second after wake up from sleep
 

Specs: Dell Latitude E6440, Bios A23
macOS Version: macOS 10.15 (Catalina)
Clover EFI version : v5070

 

Appreciate if anyone can assist or guide me on how to troubleshoot it.

 

Thanks

You're using SSDT-EC to create/add a dummy EC device in ACPI but, ideally, you should have just renamed ECDV to EC through Clover.

 

There are several things to say about your addd-on kexts:

  • USB_injector kext may not be suitable anymore. Instead, use Rehabman's USBInjectAll, after which you may run Hackintool app to generate your system-specific USBPorts kext
  • you're using latest WhateverGreen kext so AppleBacklightFixup is obsolete and should be removed
  • you're using VirtualSMC alongside ACPIBatteryManager and this may be the actual cause of your problem. I'd revert to FakeSMC and its PlugIns if I were you

 

Thereafter, make sure you disable hibernation and revert to plain old sleep as explained in our FAQ section.

Dear Herve,

 

I made the following changes:-

1) renamed ECDV to EC through Clover and remove SSDT-EC.aml

2) remove AppleBacklightFixUp.kext

3) replaced VirtualSMC.kext with FakeSMC.kext

4) USBInjectAll.kext can't detect my USB devices even though I copied in USBPorts.kext generated by HackinTool. USB_injector.kext detects everything nicely, including webcam.

 

After the above changes, system still freeze as before.

 

Attached latest debug file.

 

Thanks
