Which generation X1 do you have? (`sudo dmidecode -s system-version` to see.)

I picked up an X1 Gen4 a while back, on which I'm running Debian 12 (kernel
6.1.0-25-amd64), and it simply won't suspend, period. Or even power off
properly: it shuts down and blanks the screen, but then leaves the power
on, and I need to hold the power button for 5 seconds or so to actually
power off. This, plus a few other issues, means that it's going to get a
replacement soon if it can't be fixed.

If I replace it, I definitely want to know that the next one isn't going
to suffer from the same issue. According to ArchWiki[6] the Gen 6 does
suspend under Linux, at least if tweaked properly; no earlier Gen N that's
got a page on the Wiki mentions suspend directly, though the Gen 3 page[3]
does in passing talk about dealing with the touchpad not working after
suspend.
