You're not alone -- I recently had a heck of a time trying to get a T14s AMD 2nd gen to work well in Linux (mostly same CPU/chipset/hardware as your X13).

I never got wakeup from S3 suspend to work, it just froze; wakeup from S0ix actually worked ok for a while with a recent kernel (5.16 iirc), with a random kernel commandline addition (iommu=pt) to avoid a random 14-second pause on lid open (always exactly 14 seconds!). But wireless was still flaky on wakeup.

I played a bunch with powertop and different settings to try to get reasonable efficiency. Tried getting hardware video decode to work with YouTube/Firefox (vdpau / va-api); it sort of did, except when it crashed.

Then one day a week into the adventure, it just stopped waking up from suspend, after I-don't-know-what changed. Needed a hardware reset each time I opened the lid. I returned the laptop and bought an M1 Air instead; I love my Thinkpads and open systems but I also love good engineering.

System integration / QA / getting quality polished firmware is an underappreciated art it seems!
