Fake suspend! Battery drains as usual

Support
1

Hi. Very new laptop with AMD Ryzen 5 (4000 series) and AMD Radeon graphics. Based on what I’ve read at other forums, I suspect this particular hardware combo might not do suspend in Linux. But let’s see…

Hibernate works, but I’m a big fan of suspend, which does not work. The screen goes black after selecting suspend from log-out menu or after pushing the power button, or even after entering “systemctl suspend” in terminal.

However, the power button light stays on, I can hear the fan, and I can even toggle through the keyboard backlight brightness options while the laptop is allegedly suspended.

I’ve seen this problem reported before, but the route to a solution is not clear to me. I read this (Power management - ArchWiki) but nothing jumps at me from there. Same with this (https://classicforum.manjaro.org/index.php?topic=32803.45) and this (Laptop does not suspend when lid is closed) etc.

cat /sys/power/mem_sleep returned this:

[s2idle]

systemctl hybrid-sleep works, and if it comes to it, I would be happy with this as an alternative to suspend, but I would need help with that process. However, suspend is what I am looking for and will be first prize.

I don’t know if it’s relevant to this problem, but just in case it is, @megavolt solved a ‘blackscreen boot’ issue earlier where the problem was that the system tried and failed to load a radeon driver when the amd driver supports AMD Renoir: [Solved] Booting to black screen - #14 by megavolt

Any help will be much appreciated…

I just received my HP Envy x360 with 4700U which has the exact same problem.

EDIT:
Check if your bios has an “S3 standby” option or something similar. Lenovo also has put out a custom bios which adds support for S3 standby. If this exists for your laptop that will solve your problem. If you can you should probably still do this even once s2idle works fine.

Linux prior to 5.11 simply does not support s2idle on renoir cpus (or any amd cpus for that matter), and instead just freezes userspace. 5.11 will bring initial support:
www.phoronix. com/scan.php?page=news_item&px=AMD-S2idle-ACPI-Linux-5.11

Unfortunately there still seem to be bugs with the amdgpu driver preventing it from fully working but those are being squared away too, although it could still take some time. For more info and any updates on the current state you can take a look at this issue:
gitlab.freedesktop. org/drm/amd/-/issues/1230

That means in the meantime you’re kinda out of luck if you have no way to enable S3 in your bios. I would recommend using suspend to disk (hibernate) until other options are available (because hybrid standby will drain your battery almost as fast as using it while s2idle isn’t working).

(sorry I can’t post links, you’ll have to remove the spaces)

Suspend seems to be working with kernel 5.14.2-1. Apologies if this is old news already.
