ThinkPad T14 AMD Gen5: Battery drain during sleep on Fedora 40 (original) (raw)
September 11, 2024, 7:09pm 1
I bought two new ThinkPads T14 AMD Gen5 for my girlfriend and me for university. My gf uses the KDE Spin and I use the Sway Spin of Fedora 40 and we both have the issue that if we just close the laptop and put it to sleep the battery is drained to 0% the next morning.
I tried a couple of things from this forum and other resources, but they did not work and I am mostly confused.
I already figured out that my system is not capable of the normal S3 deep sleep but it supports S4 and S5
❯ sudo dmesg |grep "ACPI: PM: (supports"
[ 0.278545] ACPI: PM: (supports S0 S4 S5)
❯ cat /sys/power/mem_sleep
[s2idle]
The following link is the result of running fpaste --sysinfo --printonly|wl-copy
If anyone knows what else I could try please let me know. I told my gf fedora is the best sytem she could possibly have on her laptop before installing it. Now we are shutting down and powering on our computers a few times a day to even get though it on battery .

Yes, I lose about 20% battery over like 3-4h of sleeping.
This is a weak point in Fedora Linux, finding a solution would be great.

Do you think other non Fedora based Distros do not have this Problem to this extent ?
I wasn’t sure if it’s a Linux or a Fedora Problem. If its better on something else I will migrate my girlfriend’s Laptop to whatever is better for now.
Who is working in this Area in the Fedora Project?

@mpearson might have some thoughts.

I have no issues with battery drain during sleep/suspend on my P14s Gen 5 with F40 KDE (Intel CPU + Nvidia GPU). Unfortunately, I can’t really provide useful tips how to make it work for you – just wanted to let you know that it “should” be fine. Could it be that it is something specific to AMD? And I guess you have double- and triple checked that the laptops really go to sleep when the lid is closed, i.e. the LED in the Thinkpad logo is pulsating slowly?

Two things:
- There is a known issue related to the wired ethernet port. If you’re not using it then try disabling that in the BIOS as a workaround. - we’re waiting for a BIOS fix for it to be released (supposed to be tomorrow…but it’s not uncommon for dates to slip depending on how release testing goes). Your description matches what we see with this issue so I’m fairly confident it’s what you’re seeing.
- There is an upstream regression in 6.10 kernel that impacts AMD platforms with a Qualcomm Wifi. Upstream bug is 219196 – ath11k: Suspend broken in 6.10 and later on Lenovo platforms - it’s fixed and been marked for stable so it should roll out in Fedora soon (I checked and it’s not in the fedora-6.10 kernel yet…). Afraid no easy way to work around this one except downgrade to a 6.9 kernel.
If neither of the above work - try running the AMD sleep test tool ( AMD s2idle tester) and share the results.

thank you @mpearson . I disabled the wired Ethernet port and downgraded to kernel 6.9 now . I will report back if the issue is gone

Currently having the same issue on my ThinkPad T14 Gen 5 (AMD). Battery takes a dive by 10% under 30-40 minutes of putting the system to sleep. I’ve downgraded the kernel from 6.10 to 6.9, disabled Ethernet in BIOS – still no dice.
s2idle tester report
renekuhn (René Kuhn) September 14, 2024, 9:08am 9
I am in the same situation as @prgaftdrk .
Downgrading to the 6.9 Kernel and disabling Ethernet did not help.
This is the report generated by s2idle tester on my machine
I guess I broke something on my system with my experiments.
This is the report of s2idle tester on my gf’s machine with the newest kernel
The CLI outputs on her machine says
The system hasn't been configured for Modern Standby in BIOS setup
AMD systems must be configured for Modern Standby in BIOS setup
for s2idle to function properly in Linux.
On some OEM systems this is referred to as 'Windows' sleep mode.
If the BIOS is configured for S3 and you manually select s2idle
in /sys/power/mem_sleep, the system will not enter the deepest hardware state.
But I cannot find a seeting like this in BIOS
@mpearson what are some steps that I can take to troubleshoot this futher and learn whats going on here ?
For now I will research why I get the ❌ Failed to suspend error and what I did wrong there…
Do you think I should setup my system from scratch and reinstall a fresh OS ?

@renekuhn For the past few weeks, I’ve been trying out couple of 6.10.x kernels that were in the testing phase but neither one of them helped. Today, I installed the latest v6.10.10-200 kernel (it’s currently in testing) and put my system to sleep for 2-3 hours. When I’d woken up the system, battery didn’t drop a single percent. I’m gonna test it out some more and see if it remains consistent. You might wanna give it a try yourself if you’re interested. Installation is pretty straight forward.

I can confirm the same issue on Debian based distros as well. This reddit post had one major tip that helped slow down the battery drain, setting the kernel parameter acpi.ec_no_wakeup=1. I saw that someone sent a patch to Linux Kernel to do the same, [PATCH] ACPI: EC: Use ec_no_wakeup on ThinkPad T14 Gen 5 - Yutaro Ohno
Same discussion in ArchLinux: [SOLVED] Thinkpad T14 Gen 5 AMD consumes too much power in sleep mode / Laptop Issues / Arch Linux Forums

FWIW real-life data: I accidentally left my fully (95%) charged, suspended P14s Gen 5 (Intel+Nvidia) in my boss’ office on Friday and recovered it right now – battery charge dropped from 95% to 20% within those ~70 hours.

I maybe had a similar problem at the end of the last year( English Community-Lenovo Community ). Thank God I bought my ThinkPad P16s Gen 2 AMD online and was able to return it to the dealer. Lenovo did not provide any useful help to my queries. I then bought a Lenovo ThinkPad T16 Gen 2 with 13th Gen Intel® Core™ i7 and everything worked fine.

FW update, that should fix this issue, has been delayed by a couple of weeks. Expected end of September now.

Same issue with Intel. Nothing happens when I close the lid and selecting ‘Suspend’ just locks the screen. Tested on Fedora 40 and 41 Beta.

Hi!
That will be a different issue - and we’ve completed certification on that platform (unlike the AMD version) so there’s something else going on.
Rather than add noise to the AMD thread with a bunch of Intel related debug, can you create a new thread please? Or post a ticket on the Lenovo forums (English Community-Lenovo Community).
Note - recommend running the Intel S0ix test tool to check the logs from that: Intel S0ix tester

Hi Mark, I just realized you’re the same person who replied in the kernel mail thread.
if this is an issue in the Lenovo FW I would rather fix it there instead of introducing a quirk into the kernel that might later need to be removed. This platform is getting full Linux support.
Where is the place where firmware (I assume FW is firmware) discussions happen? I would like to monitor the progress and see what else happens there 
Thank you for your work,
Subin

Hmmm - interestingly I don’t have a main public ticket that I’m pointing to for this issue.
It was originally found during our certification process and the internal ticket is LO-3089…but I appreciate that’s not super useful
I’ve added this forum thread to the internal ticket so I should remember to update here when the FW is released…fingers crossed.
Our forums also have these two threads that are for the issue:

Thank you so much! Finally I get to talk with the right person I had contacted Lenovo India support team, they were kind of clueless but I had sent them the link to this thread and other threads complaining as well.
This is the first time I’m exploring sleep state on Linux, and that brought to me S0 Modern Standby vs S3 (https://www.youtube.com/watch?v=OHKKcd3sx2c). I’d like to ask the question: does the hardware of this machine (ThinkPad T14 AMD Gen5) actually still support S3 sleep but it’s just that BIOS has it hidden/deprecated? Would it be technically possible to bring S3 back?
I come from a M1 macbook and the battery saving it has on sleep is just wow, I believe only S3 sleep can come close to that level of battery saving on sleep mode.
