My wife just got the Carbon 6th gen. There is an ACPI patch to restore S3. See https://delta-xi.net/#056. Once you've got the patched dsdt.aml, I highly recommend not following their directions, and just loading the file in grub by creating /boot/grub/custom.cfg with the line:

acpi patched_dsdt.aml

This has the advantage of not requiring any manual intervention every time your kernel is updated. The downside is that if you try to dual boot W10, it will BSOD on boot with an ACPI error. To overcome this, take the original dsdt.aml and load it in a custom (not auto-probed) menu entry for windows. You can just clone the auto-probed line, and add before the chainloader line:

acpi old_dsdt.aml

I already did it, and I'm really glad I can do that since I have no use for S0I3 and I'd rather have the extended battery lifetime. However on windows there's no way to disable this sleep mode, and the laptop has consequently lasts way less when put to sleep in Windows 10, even compared to the 3rd edition (which we also have so that I can compare). How does this put linux in power management, huh?

Sadly, the 6th edition of the Carbon also runs waaay hotter than the 3rd, and I did notice occasional coil whine which was previously absent. When running normally the kernel writes regularly about thermal warnings. It seems that power and heat management is not well managed in this edition, and I see similar reports for the x1 yoga 3rd gen.
