I have a Lenovo thinkpad T14 gen 1.
Certainly not the fastest, but in have yet to find a problem running Linux. It suspends, hibernates and I haven’t found any quirks yet
Everything works and it’s built like a tank.
Battery has 600 cycles and I still get 4 hrs out of it, when in low power mode.
I’m pretty sure the newer models aren’t that well built and supported. Maybe the gen 3 and 4 of the T14 is similar good. But YMMV..
