I think in general S3 has worked on sandy/ivy recently, but cannot tell
about X230 for sure.

We'll likely need coreboot debug logs. You can get one for normal boot
using the tool under utils/cbmem, that might help us already. To collect
log from failing S3 resume you need to learn about usbdebug and possibly
get some FT232H or beaglebone hardware.
Also check ifdtool -d output. S3 resume requires host CPU has write access
to the part of SPI flash where MRC cache is located.
