I disagree with the "Incomplete" status of this bug, specifically
because it is now Expired. This bug is infuriating. Any time I reboot,
if I forget to cat deep to /sys/power/mem_sleep, my laptop is dead the
next time I go to use it. The battery lasts for days when using "deep"
sleep.
In s2idle, it actually heats up in my backpack, and I worry it may
overheat if I don't notice it.
I understand that the bug may not be fully understood yet, but allowing
the bug to expire is entirely inappropriate. Even if only for this one
reason, it should not be "Incomplete".
A proper s2idle would be wonderful, but until then, deep should be the
default.

Title:
Dell XPS 13 (9370) defaults to s2idle sleep/suspend instead of deep
Status in linux package in Ubuntu:
Confirmed
Bug description:
It seems that the Dell 9370 is set to go into s2idle mode rather than
deep sleep, forgoing significant power savings.
I have confirmed this by suspending and then checking:
sudo journalctl | grep "PM: suspend" | tail -2. If the output is
PM: suspend entry (s2idle)
PM: suspend exit
cat /sys/power/mem_sleep showed
[s2idle] deep
As a temporary fix, I typed
echo deep > /sys/power/mem_sleep
as a root user (sudo -i).
Then the output of cat /sys/power/mem_sleep was
s2idle [deep]
After suspending now,
sudo journalctl | grep "PM: suspend" | tail -2 returns
PM: suspend entry (deep)
PM: suspend exit
I have made this permanent by editing
/etc/default/grub
and replacing
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
with
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash mem_sleep_default=deep"
then regenerating my grub configuration (sudo grub-mkconfig -o
/boot/grub/grub.cfg).
This appears to be working with no ill effects.
