UPD: I have tried to suspend from live Linux Mint 17.3 XFCE. The symptoms were exactly the same: the system did not wake up.
I am running
$ uname -a
Linux inspiron 4.1.15-gentoo-r1 #2 SMP Thu Feb 11 08:49:44 MSK 2016 x86_64 Intel(R) Atom(TM) CPU N455 @ 1.66GHz GenuineIntel GNU/Linux
I have installed

When I request the system to suspend, it works: the HDD stops making noise, the screen turns off and the power indicator starts slowly fading in and out, just like it did on Windows. However, when I try to resume, the screen doesn't turn back on. The HDD does fire up again and the power indicator reverts to being constantly on.
In order to debug this, I copied over a version of /var/log before the suspend, then I suspended, attempted a resume, and when it failed I shut down the machine by holding the power button for 5 seconds. Then I booted into a live system from a USB stick and copied over an updated /var/log. Here is the diff between the two versions:

I don't see anything suspicious in it, with the exception that it doesn't seem to contain anything about the resume.
The Gentoo Wiki mentions that "disabling the security chip in BIOS" may help, but I don't seem to have any setting in BIOS saying anything about "security chips".
What could be the problem and how could I fix it?

This is a common problem with graphics cards, which are not woken up properly. Your case is kinda weird as your laptop has no dedicated GPU and the chipset is produced by Intel, which usually has good opensource drivers. – rindeal – 2016-03-08T00:18:02.950
@Pastafarianist have you found a fix for this issue? I've been facing a very similar issue with my Inspiron 5558. – Robbie Wxyz – 2016-06-10T23:18:04.777
@SuperScript I have installed Manjaro (Xfce edition) and despite the fact that power management is still broken in numerous ways (random freezes on shutdown, screen is solid black color after closing the lid and waiting for a while, tty1-6 don't work), suspend & resume does work. Usually. – Pastafarianist – 2016-06-11T10:42:13.980
