Hackky

Hello @Lorys89, Thank you so much for sharing your EFI. I can boot to macOS and use Thunderbolt ports using your EFI. I have few things I would like to ask. 1. Can we enable S3 sleep or is it just me that cannot enable S3? I tried to enable S3 sleep after disabling S0 with UEFI mod, but every time the device wakes up to Dell logo, then gets stuck there. Only S0 deep idle works for me. (I don't know if this is affected by having most recent BIOS version 1.39) and the same behavior on Windows 10 system as well. Stuck at Dell logo after waking with S3 sleep attempt. 2. Thunderbolt PCIe Device Enumeration Mode (Native mode vs BIOS Assist) This is rather an odd behavior. Occasionally on boot I get this warning message saying "Thunderbolt PCIe Device Enumeration Mode Has Switched to Native" or " Thunderbolt PCIe Device Enumeration Mode Has Switched to BIOS Assist". I don't know what trigger this behavior but When in "Native Enumeration Mode" TB3 hotplug works. But in BIOS Assist mode, hotplug does not work and TB3 will only work when connected before cold boot and if the TB device is not connected when booting, RP05 in ioregistryexplorer is empty. It seems that Native Enumeration mode is achievable after hard RTC reset and setting Thunderbolt Auto Switch to disable in UEFI mod but after awhile it goes back to default and I get the warning message about BIOS assist mode on boot again. @Lorys89 I have the exact same spec as yours but on 1.39 BIOS. Are you experiencing the similar behavior? I really like this laptop but not being able to enable S3 really troubles me. What I'd like to know is if unsupported S3 sleep is due to having latest BIOS that some how does not properly support it. Sorry for asking too much questions.
