This has been my experience with my T14s Gen 3 (6850U). S3 sleep is no longer available, and S0 sleep fails to resume at least once a week. Even in Windows (10 and 11). I eventually got them to replace the machine with a new one, and it has the same problem. Otherwise I like the laptop. But the inability to wake from sleep cancels anything good about it and makes it not much more than a paperweight.
