Sleep Battery Drain -- Deepin

When I go into sleep mode (let’s say before bed – at 80% battery) and then I open up my laptop again later (when I wake up), my battery is completely drained.

I tried:
(1) echo deep > /sys/power/mem_sleep after I saw that cat /sys/power/mem_sleep had s2idle selected instead of deep. But that did not seem to fix the issue… that being said on reboot it is back at s2idle instead of deep… RedditPost. If I also then try to write mem to /sys/power/state after that, the laptop screen will not turn back on no matter what and I have to hard shutdown and restart (which I know is bad, but I try everything else first).

(2) I read in the above link, that to make the change to deep permenant to try changing "in your kernel cmdline in your bootloader: mem_sleep_default=deep" – but I haven’t figured out how to do that or where that is.

(3) TLP is already installed

(4) While I see reports of sleep being an issue for some Dell XPS computers, sleep has worked fine in Windows and a previous linux installation before on this same laptop

(5) Output of systemctl suspend journalctl | grep "PM: suspend" gives Jan 19 09:28:08 keith-xps139300 kernel: PM: suspend entry (s2idle) Jan 19 09:28:31 keith-xps139300 kernel: PM: suspend exit – which I want deep, but not sure how to change that

– If I had to guess, I hope that I just need to figure out how to execute #2 “change mem_sleep_default to deep in linux kernel commandline”. I saw that mentioned here too Linux Sleep States but again, I cannot figure out how to actually do that.

Here’s some potentially helpful information on my system:

Thank you!

You say this is a Deepin issue - have you tried with a different DE?

I have not really. I guess I did not know under what category to post it on or where the issue stemmed from. It worked fine when I had Manjaro Gnome and Plasma before. But I have not tried with a different DE on EndeavorOS. I will try to figure it out from your link. Thank you!

OK, to document what I’ve done in case it helps someone else in the future:

I edited /etc/default/grub and appended my kernel option mem_sleep_default=deep between the quotes in the GRUB_CMDLINE_LINUX_DEFAULT line… so it ended looking like:
GRUB_CMDLINE_LINUX_DEFAULT="quiet loglevel=3 nowatchdog mem_sleep_default=deep"

Then automatically re-generated the grub.cfg file with:
grub-mkconfig -o /boot/grub/grub.cfg

All of this I got thanks to your link in your previous comment, under Grub section for Kernel Parameters. I am hoping that solves it and I will report back if not!


OK. That seems to make it go into Deep Sleep, but now it can’t wake up from it! If I touch the power button it makes sounds like it’s turning on (I hear the Deepin notification sound) but the screen stays stuck at the Dell Loading screen (black screen with white Dell symbol) and won’t change from there :/. Maybe Dell made deep sleep impossible to use/wake-up-from? Or is this a common issue for many computers and deep sleep and there is another work-around? I had to hard restart it with pushing down the power button and holding it down :/.

If sleep works with other distros then you’d have to look at the differences. One good starting point is the kernel - try linux-lts and see if that makes a difference, there are some older LTS kernels available, and other kernels like linux-lqx which are compiled with different settings than linux.

I appreciate your help. Unfortunately using linux-lts did not make a difference. I will try other kernels later… I was pretty sure it worked with other distributions, but it has been a while since I last tried, so perhaps I am incorrect… I remember it being a struggle with Windows for a while, but then a BIOS update “fixed” it… I wonder if it’s another issue with that sort of thing. It looks like online that a lot of Dell XPS are “unable to go into an S3 state” … which I don’t completely understand because it appears it goes into S3 fine now, but can’t get out of it properly…

It will also be reading the model-specific page on the Arch wiki:

Amazing. So to document: I edited /etc/default/grub and appended mem_sleep_default=deep and intel_iommu=off to GRUB_CMDLINE_LINUX_DEFAULT, so it looks like GRUB_CMDLINE_LINUX_DEFAULT="quiet loglevel=3 nowatchdog mem_sleep_default=deep intel_iommu=off"

Then I regenerated the grub.cfg with grub-mkconfig -o /boot/grub/grub.cfg

Then restarted, clicking F2 repeatedly to get to BIOS, went to POST Behavior, disabled “Display Logo Sign of Life” saved/exited.

Then I tested it by suspending, and then clicking the power button to unsuspend and it successfully came out of suspend! I am not sure if the intel_iommu=off was necessarily needed or not… also unsure if it has any repercussions.

I will test it more tonight by leaving it in sleep and then checking the battery drain before marking as solved for sure.

But thank you so very much. Extremely helpful!

OK we’re close – I tried closing the lid yesterday (because I have it set to suspend on lid closure) and then in the morning my battery was completely drained… but I suspect it’s because it is no longer suspending at all on lid closure (I confirm this by closing the lid, waiting a bit, and then opening to a completely “on” screen…). I have confirmed though I can suspend it by using the normal on the screen way, or when I have it set to suspend with power button, that works too.

Anyways, I suspect it not suspending with lid closure may be a separate issue.
