The XPS13 DE could be construed as that, it's only available with Linux, has different hardware than the standard XPS, and is very routinely called "Linux Developer Edition" by the press (though I couldn't say if Dell ever called it that). |

Long story short, on at least a few ones I explored deeply (The 7275 or the 9250 can't remember) the dell just can't sleep right, even on Windows.
What saves the day is Windows proper sleep support, including hybrid sleep, that prepares for the worst (save an S4 hibernation image) and hopes for the best (wakes up time to time to check what's left in be battery, to decide when to give up when the power goes below what's called the sleep budget, to ensure the laptop will be able to wake up)
The beauty of it is when laptops have a wrong bios that just cant sleep, windows hides the bug away.
The sad part of it is that Windows takes the blame (the laptol takes a long time to wake up from suspend to disk, and shows the power has been almost exhusted) for the manufacturer incompetence.
I think this is why they introduced a change early on in Windows 10 that when tne measurements at the beginning of the sleep showed the power was going down with a dangerously steep slope, it was a clear sign Windows was running on a poorly designed laptop, and that it should abandon all hope of s2idle working right, and instead just powed off the poor laptop to put it out of its misery and instead try to do a fast start with the hibernation image the next time
The worst part is that the dangerously incompetent people at dell, unaware of their own incompetence (they couldnt write proper ACPI sleep in the first place) decided to double down on the stupidity and did some weird things to mislead windows and prevent it from giving up on s2idle.... which is why dell latops have acquired a reputation they may catch fire when in a bad.
It's all both funny and sad, so I applaud lenovo for finding ways to make S3 sleep work on laptops like the x10 gen1, which uses a generation of intel CPU where the excuse of manufacturer of 'made for linux' laptops is that S3 can't work because it was no longer supported by Intel anymore...
