Sleep Not Working for Lenovo P14S Gen 6

Hello folks,

Sleep seems to not be working at all on my Lenovo P14S Gen 6. I have the AMD variant with the Ryzen AI 370 with no eGPU, just iGPU.

When I tried to suspend the laptop, it initially succeeds and the power button flicks on and off. Once in this state, any keyboard or mouse input does NOT wake it up at all. I have to hold the power button for awhile for it to forcefully shut off and restart new.

Looking on the Wiki, it mentions there are issues of the laptop. Looking in the older Gen 3, it looks like there's a bug in the last few generations in UFEI. Unfortunately the option to fix it is removed as there's no S3 option on this laptop. I also tried resetting UFEI to default as it was mentioned elsewhere to fix it but it doesn't solve the problem.

On Power management, I checked and I only have s2idle.

cat /sys/power/mem_sleep
[s2idle]

I've also edited `/etc/systemd/sleep.conf` but nothing helps. I assume this is mostly a hardware issue that I can't remedy at all? Or does anyone else have any recommendations?

EDIT: I've only used sleep once when I initially setup the system about 9 months ago and it worked. I have not tested it until today. I'm on the linux-lts kernel if that matters here.

Re: Sleep Not Working for Lenovo P14S Gen 6

Its a shame no one has replied with a fix for this. I have tried a couple AI options but none worked.

I cant put my finger on when it stopped working, but it was within the last month or two, by now. I was messing with Fedora and there was a bios update and then reinstalled Arch and there was a kernel update to the 7.x series (I think it was around then 7.0 came out) and it stopped working after that.

It appears to be a real issue too because we have 4 of these class of laptops at work as well as mine at home and all 5 seem to the same issue on various Linux distros, but not on Windows, so I dont think its a BIOS issue.

My other Lenovo laptops dont have this issue, but the other ones are various gens of Intel CPUs.

Re: Sleep Not Working for Lenovo P14S Gen 6

OK found a fix for my laptop:
Lenovo P14s AMD Pro9HX

BIOS
        Vendor: LENOVO
        Version: R2XET39W (1.19 )

Set a UMA Frame Buffer fixed value instead of Auto - I used 16gb
Also set this in /etc/default/grub:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.dcdebugmask=0x10 amd_iommu=off"

Added: amdgpu.dcdebugmask=0x10 amd_iommu=off

Not sure which one fixed the issue, but it works now.

I can let the laptop sleep by leaving it alone while its on, and pressing space bar fixes it. And, I can use the lid now.

Hope this helps someone
