Thinkpad P14s AMD 2nd gen: suspend to RAM doesn't work

dk flag

I own the new Thinkpad P14s AMD 2nd gen with Ubuntu 21.04 and full disk encryption. It almost works out of the box except for Wi-Fi (that can be fixed with this driver) and suspension.

Actually, I'm not totally sure where the problem is: if I try to suspend, all keyboard lights switch off, except for the power button that stays on. When I try to resume from suspension, keyboard lights switch on but the screen doesn't and I can do nothing except forcing the shut down by holding the power button.

Can the problem be related to full-disk encryption? Or maybe some kernel problem with this new laptop?

I fixed the issue, which wasn't related to disk encryption: this laptop has the S0 sleep mode activated by default, but Linux supports S3 (suspend to RAM).

To fix it, from BIOS → Energy switch the sleep mode from Windows (S0) to Linux (S3) and suspension to RAM starts working!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
