๐ S3 Deep sleep on Dell

I just received a Latitude 5430 (12th gen Intel CPU). As usual with Dell, S3 mode is disabled...
There is a setting in BIOS that says (Block Sleep) to disable S3 mode, but it's unchecked (so S3 is enabled, right ?), but the ACPI DSDT table doesn't show to the kernel that the S3 mode is supported.
ACPI: PM: (supports S0 S4 S5)
Anyway, I got the DSDT table patched, and now ACPI advertise for the S3 mode. Now when I close the lid, the PC goes into deep sleep mode. But when I open the lid, the PC seems to resume (keyboard is illuminating, CPU get warmer) but the screen stays black, forcing me to a hard reset. Last line on dmesg is :
kernel: PM: suspend entry (deep)
Please, does anyone knows how to fix that from there ?
