Suspend/hibernate works on thinkpads with a moderately recent Linux kernel and a bios toggle.

Source about the BIOS part? I own many thinkpads and use them at work too and never had to do anything with BIOS settings.

Some thinkpad models (e.g. 6th gen x1 carbon) didn't ship with bios support for the s3 sleep state. It was added later. Even the ones that were shipped with an updated bios did not have the option enabled (because windows uses "modern sleep"). I don't have a source listing all the lenovo hardware that needs to be configured for proper linux sleep.
