Dell XPS is the only laptop where I have seen this working reliably. Worst part is that thanks to zram, many distros removed hibernate functionality. So its not possible now to either sleep or hibernate on many laptop/distro combinations. This makes Linux unusable in most cases due to battery drain (and some times even dangerous as laptop gets super hot inside bag etc).

"Dell XPS" is too generic a term to be useful. I've got an old XPS 13 which works perfectly; I also got a newer XPS 15 (top of the line, 4500€) which never managed to sleep correctly (thanks to Intel s0ix hybrid-suspend) and often overheated in the bag. I got rid of the latter after 1 year, it was a mess to use.

  The one I have is 2021 XPS 13. May be the 15 model is wired different somehow.

My newer XPS laptop doesn't even have an S3 sleep state. At least it can hibernate under OpenBSD, I guess.

I can't speak for S4/suspend to disk level hibernation, but regular S3/sleep when I close the lid has worked perfectly for me since 2008. That isn't to say that it's worked out of the box. When I install Linux on a laptop, I'll put some effort into making sure everything works as wanted and this might involve adding kernel flags or mucking with dbus, and it certainly involves some research. If you expect any open source OS to behave like a proprietary OS you bought a license for, you're likely to be disappointed. If you come in with the expectation of learning to solve problems for yourself you'll fare much better.

  Unfortunately s3 has been removed from everything after tiger lake in intel chips, replaced with s0ix, which has caused a bunch of problems. For example, https://old.reddit.com/r/System76/comments/k7xrtz/ill_have_whatever_intel_was_smoking_when_they/ https://old.reddit.com/r/System76/comments/k7xrtz/ill_have_w... Sleep works fine in my alder lake(12th gen) Framework on Fedora, as in it actually sleeps when you close the lid, but it won't last a week like a mac.

    By any chance do you know if AMD Ryzen CPUs retain the s3 sleep/resume facilities? As in can I get a Mac like suspend/resume behaviour with Ryzen and Linux?

      > As in can I get a Mac like suspend/resume behaviour with Ryzen and Linux? What do you mean? Reliably suspending on lid close? That will depend on the system. My 12th gen Framework with Fedora is very reliable in that way. Battery lasting a week+ when sleeping? Don't count on it but sleep time will depend on the system. Even s3 sleep varied a lot. Some systems wouldn't suspend ssd during s3, for example. Arguably s2idle/s0ix is more mac-like, in that it is faster to sleep/wakeup than s3, which can take 6-10 seconds. It's just not as well supported and is much more flexible, in the sense that the os has more control over what is running during sleep. Windows is supposedly takes a strategy of incrementally powering down devices as sleep duration increases to preserve battery.

        > s3, which can take 6-10 seconds. What? S3 should be well under 5 seconds. 10 seconds is like a whole clean boot, or resuming from hibernation on NVMe.

        > My 12th gen Framework with Fedora is very reliable in that way. How long does it take for your Intel Framework machine to sleep properly upon shutting the lid, and how long until it is ready to use after you open the lid?

My xps never hibernated properly and the battery started to swell, which messed up my touchpad
