I have an oled thinkpad running fedora that has never had a sleep issue. Excellent touchpad as well. Thinkpad X1 Carbon.
I have a thinkpad p1 with popos, but it doesn’t sleep properly. Closing the lid causes it to be super active. I have to lay it down up side down so the ventilation gaps are not blocked, otherwise it overheats. Burned one SSD this way.
Which version? I have a X1 Carbon from, uhh, 2017? It supports S3 sleep. I'd think about an upgrade, if only I wasn't worried about sleep issues. I run Debian if that makes any difference.
Actually now that I think about it, my visceral reaction is one of dread: a feeling the trouble will be more than the benefit of a new computer.
For me the touchpad experience is not just about the hardware. I got a Magic Trackpad for my Linux desktop hoping that it would at least be somewhat comparable to my MacBook. But scrolling and gestures are nowhere near as consistent and fluid as in macOS since the software support just isn't there.
As a fairly typical example, getting Firefox on Linux to actually scroll smoothly takes googling and fiddling with settings. Gesture support is hit or miss. On macOS, Firefox behaves just like any other native app in this regard.
