Well idk what about my setup isn’t modern? I guess my laptop is a few years old but its not that old. 2020 model. and I run debian stable so not bleeding edge but not crazy. My laptop is just one that ships with an ubuntu option and so it has good linux compatibility in general. So that probably helps.








that is what my laptop uses. Why mine works and yours does not is very complicated. I looked into it a bit. Firstly, my laptop is a Dell Latitude 7400 (non 2 in 1 model). This supports both modes, but mine is configured to use s2idle. One of the huge pluses of this laptop is that is had a stock Ubuntu option when it was sold. You could get it shipped to you with Ubuntu preinstalled. Now, I don’t use Ubuntu I use Debian but the Dell firmware is still configured to support Linux out of the box. So Linux isn’t being treated as a 2nd class citizen for this laptop. It’s getting the VIP treatment just like Windows.
Another thing is my actual configuration. Thermals prior to sleep matter a lot. If you laptop is too hot it will fail to enter the sleep state it needs to. Meaning it stays hot and continues to run and dies fast. I have heavily modified my laptops thermals. I have the CPU capped at 2.5Ghz, I have tlp running, and I have high quality thermal pads added inside the chassis to spread heat around to the magnesium back plate. Because of these mods my laptop does not use its fan, and the CPU hovers around 50C passively while in use. This means I never have a problem with suspend due to thermals.
I also have components, like my SSD, that are modern and support deep sleep states. My SSD is a WD Black SN770 1TB. Which is both pretty power efficient and supports deep sleep states.
Another thing is that the tlp and powertop tweaks are preventing wakeup triggers that would pull it out of suspend. and of course the last big thing is just that I keep my firmware up to date. Dell released firmware specifically to fix modern standy issues and I have that update. Dell ships easy firmware updates to linux users and you can install them with a few clicks and a reboot. Another advantage of the Linux native support.
Really can’t reccomend the laptop enough if you want a used business class machine its great and you can find them for 200ish$.
