Framework 13 Intel Core Ultra Series 1 155H Hibernation Increases Overall Power Consumption

zero2null · May 17, 2025, 2:00pm

Hi all,

I am running Linux (Nixos) on my Framework 13 with an Intel Ultra 7 155H board. This works mostly perfect. However, I am facing some issues after my system was in hibernation. Are there any people around here also using Linux and hibernation on the Intel Core Ultra Series 1 boards?

My system enters hibernation with no problems. At first glance, it also restores correctly from hibernation. At a second glance, however, the system does consume noticeably more power and also fails to sleep after it was hibernated. From a power consumption point of view, it looks like this (measured with powertop):

System newly booted and Gnome desktop at idle: 3.8 .. 4.5 W
Hibernate and resume from hibernate
Again at Gnome desktop in idle: 5.7 .. 7 W

Once I reboot, everything is OK again.

Instead of powertop I can perform the same measurement with a simple AC Wattmeter and get basically the same results. The AC Wattmeter also revealed that the whole system (after being hibernated at least once) no longer goes into any deeper sleep, as the power consumption is about 4W in sleep (suspend). Prior to hibernation, it was about 1.0W.

The effect is 100% reproducible. So far I have tested this with Nixos 24.11 (Kernel 6.12, 6.13 and 6.14), and the result is always the same.

I ran S0ixSelfTestTool before and after hibernation, and the results are significantly different. Here are the most prominent parts of the S0ixSelfTestTool logs. Complete logs are attached below.

Pre-Hibernation:

CPU Core C7 residency after S2idle is: 36.52
CPU Package C-state 2 residency after S2idle is: 1.04
CPU Package C-state 3 residency after S2idle is: 0.00
CPU Package C-state 8 residency after S2idle is: 0.01
CPU Package C-state 10 residency after S2idle is: 93.77
S0ix residency after S2idle is: 93.79

S0ix substate after S2idle:
  S0i2.0 S0i2.1 S0i2.2

S0ix substate residency after S2idle:
  1875762322 99472071517 0

S0ix substates residency delta value: S0i2.0 0

S0ix substates residency delta value: S0i2.1 14057481

S0ix substates residency delta value: S0i2.2 0

Your system only get shallower S0ix substate residency: S0i2.199472071517

Need to debug why not deeper substate: S0i2.2

Post-Hibernation:

CPU Core C7 residency after S2idle is: 36.27
CPU Package C-state 2 residency after S2idle is: 94.11
CPU Package C-state 3 residency after S2idle is: 0.00
CPU Package C-state 8 residency after S2idle is: 0.00
CPU Package C-state 10 residency after S2idle is: 0.00
S0ix residency after S2idle is: 0.00

Your system achieved PC2 residency: 94.11, but no PC8 residency during S2idle: 0.00

This tells me that there is something going wrong with the power state management of some PCIe components. Due to the fact that this happens only after hibernation, I assume this is more of a SW than an HW issue. But keep in mind, I have no expertise in HW driver development on PC hardware, so I might as well be wrong.

The full pre-hibernation log also reveals that there might be some potential to lower the standby/suspend power consumption, but I guess that’s a different story.

Besides the reported issue, hibernation seems to work fine. Even suspend-then-hibernate otherwise just does what it says.

Thanks

Maybe patch 2 from this series helps

(Patch 1 will only help with s5)

zero2null · May 17, 2025, 6:15pm

Thanks for your response. I tried your patch. Unfortunately, this resulted in a very unstable system. After booting, everything was as before. But once I hibernated the system, things went sour. I made multiple tempts, but the system always ended up crashing. Either during wake-up from hibernation or shortly after.

Mario_Limonciello · May 17, 2025, 7:21pm

Huh interesting - it just ports everything from suspend to hibernate. Is everything stable for suspend?

zero2null · May 18, 2025, 7:18am

Yesterday I forgot to disconnect the USB Dock, which seems to cause the crash. Sorry for the confusion! I checked again with only the laptop. The patch is stable, but the problem with increased power consumption after hibernation is still there.

If I understand your patch correctly, it addresses increased power consumption while in hibernation. In my case, the system appears to be completely off (i.e., 0W) while in hibernation. Only after it is restored is the consumption increased by about 3W.

Mario_Limonciello · May 18, 2025, 11:27am

Is the issue still presented if you hibernate followed by suspend?

Mario_Limonciello · May 18, 2025, 12:01pm

The point of the patch series was specifically to improve s5 power and attempted to fix any incongruent behavior between Windows and Linux for that state. I’m surprising you’re actually getting 0W for hibernate.

How accurate is your wattmeter supposed to be? Are you testing with battery physically disconnected? On framework BIOS there would be a temporary disconnect option in BIOS. That should emulate a physical disconnect without having to open the chassis.

I did some measurements with your patch, running on battery, display on minimum brightness, booted into Gnome desktop, and a terminal running powertop. The readings are the discharge rate shown by powertop:

Boot up
3.5W
Suspend and wake up
3.3 W
Hibernate and restore
6.0 W
Standby and wake up
5.2 W

With every step, I waited at least half a minute for the readings to stabilize. There is some fluctuation, but still a significant difference between before and after hibernation.

Regarding the accuracy of the AC wattmeter, it’s one of the simple plug-in types that you put in between the wall outlet and your device, with a small display showing the wattage and consumed power. It shows 0.1W resolution, but I doubt it being so accurate. I have no further information; other than that, I have used it on other devices, and the readings are consistent and feel about right. Though if the 0.0W are actually 0.0W or just less than, let’s say, 0.5W, I don’t know.

I’ll do some more measurements on the AC side with the battery disconnect option later.

It would be interesting to repeat that without my patch to see if it’s even helping your issue at all.

It sounds like there are some remaining differences between hibernate and suspend though. IMO you should bring these findings to a kernel bugzilla to discuss with Intel developers.

A shot in the dark, but Windows will load more stuff (probably related to hibernation) and won’t put them away until you clean boot.
This is the same reason why (on both Linux and Windows) if you don’t turn off your computer for .. say, 15 days. You see the memory useage increase. On Linux it’s better, but it’s happening.
Suspect maybe that’s the same situation with Linux?

I did some measurements on the AC side with the battery disconnected. Same. Then I reverted your patch and checked. Again, no change, same problem

As the S0ixSelfTestTool output points towards the PCIe system (in particular the SSD and the WiFi card), I’ll try to find an external disk to boot from. Maybe things change if these two PCIe connections are not used.

Prior to the Framework, I used a Dell XPS, and I had the system running for months at a time, no problem. At the same time, the XPS had a very good suspend, so I did not use the hibernation. The Framework has (at least with the latest kernel versions) a rather high power consumption in suspend. So I decided to use suspend-then-hibernate. That seemed to work very well; only it increased the power consumption even more… Then I started to pay closer attention to what was going on exactly.

Unfortunately, I don’t have a Windows installation on the Framework, so I can’t compare.

Mario_Limonciello · May 19, 2025, 6:36pm

OK, well you’ve at least ruled out that it’s not a PCIe root port problem if my patch series didn’t change anything for S4.

I’d say get this on a kernel bugzilla and hopefully Intel developers will have some suspicions from your debug data.

Funny enough older systems seem to handle sleep/hibernate a lot more graceful. Expecially Dell, who builds some pretty nice code for the BIOS.

Thinkpads (after the modern standby) just “work” (except it doesn’t, there is a un-configurable hardware timer that sleeps the system regardless of Windows settings). But it does sleep.
