Thanks. The posts says all AMD-based ThinkPads are affected. And I can't confirm that with both of my T14 Gen 1s which I leave on S3 for multiple days. I haven't tried the S0-something yet, but will do. It looks like you did way more research than me, so I believe that it's a real issue. Perhaps it's down to individual component combination, like planar revision, battery, etc.?
