Almost no modern sleep modes are able to work with Linux properly either, and BIOS support for S3 sleep mode is slowly being removed by certain larger manufacturers. Very crappy.
Linux supports s2idle/s0ix just fine, though I guess it will depend on hardware like suspend always has done. I have a laptop which only supports s2idle and it almost always works fine. (There are issues in Windows too though).
However, it is still very crappy, because there was never anything wrong with S3. It comes up in a second, and the battery discharge rate is low enough to leave it suspended for days without worrying. The latter feature is actually important - coming in 0.1 seconds as opposed to 1 is not important.
Seconded. I s2idle my ThinkPad Z13 (running Fedora Bazzite) multiple times a day, every day, and have zero issues. It sleeps well with very little drain (I actually leave it in this state overnight), resume is instant, and it works perfectly.
Get a system that's been designed with Linux in mind (and a sensible distro), and there should be no issues with sleep, @[email protected]
That's the point of this article and my comment though. Newer machines are having these options removed because of pressure from Microsoft. It's a crapshoot.
I just shutdown now and I'm running Linux Mint on older Lenovos with S3. I tried to add old S3 sleep manually in Mint but it never quite worked right and at times the laptop actually froze instead of sleeping with the CPU on and the fans running.
I just go to shutdown instead. It's annoying as the idea of instant resume when opening the laptop would be great but I also don't wanted a cooked CPU with a dead battery.
