Tested with Linux kernels 4.15.6 and 4.16-rc3.
Boot message shows no S3 (suspend-to-RAM) support:
ACPI: (supports S0 S4 S5)
On the X1 Carbon Gen 5 and others, it shows S3 support there.
We are tracking this issue here: https://bbs.archlinux.org/viewtopic.php?pid=1771210
Unfortunately, this makes using Linux on this laptop quite a pain right now.
As far as we can tell from other computers that had similar issues in the past, it requires a BIOS update from Lenovo to fix.
