It’s still a bit iffy. The lack of a proper S3 sleep state is a big, big problem for me. I lose about 6% of the battery life an hour in sleep on F28, and it generates enough heat that I don't feel comfortable putting it in its sleeve while in sleep. Some people have had good luck patching the ACPI tables, but that doesn't work on every distro. I can hibernate okay, but that's really much worse than sleeping.

Other than the power issues, it's a lovely laptop.

I don't regret buying it at all because I don't really mind shaking out problems with new hardware and I usually keep my laptops for ~6 years, but if it's a big deal, I'd buy a used 5th gen X1. Those work flawlessly.
