I’m also having these performance issues, but only after plugging in the laptop. If I reboot and it runs on the battery, everything works as expected. Here’s a thread that describes similar issues: Link :: Hoping to find a fix for this; pretty sure it only started happening after some recent package updates.
Thanks for the reply; I’ll watch the other thread closely.
Just as to the ‘recent updates’ comment: I played with the laptop the day it arrived, without upgrading. So, possibly Purism support should know what image they installed. The fan issue appeared pretty much immediately, and until I realized that it was linked to sleep/wake-up, I thought I had received a defective unit (pretty ‘funny’ as I am in Europe). The point I am trying to make is that a ‘sudo apt dist-upgrade’ installed about 540 updates, so the original image cannot have been extremely recent. I don’t have the machine here, but could check. I think from memory kernel jumped from 4.15->4.16.
Also, I have the phenomenon a bit in reverse. I sometimes can avoid
starting the fan full blast (and low frequency) when plugging the laptop in.
Then, over the past 18 months similar problems seem to have plagued other distributions on ‘regular’ hardware (e.g. Lenovos) so I am starting to concede that this may be a wider kernel issue.
Thanks again,
Stefan
Hmm, good to know. My librem is my only machine right now; didn’t realize there were wider performance issues. Strange that we have similar issues with different sequences. I guess I’ll keep monitoring the threads and work with what I’ve got.
Same issue. Librem 13v3. For me, this happens infrequently, but only:
- When the laptop is not powered
- Immediately after waking the laptop from sleep by opening the lid.
It happens roughly 1/20 times I wake the laptop from sleep.
As noted above, symptoms include:
- Fan running at full blast
- A very laggy UI, in spite of negligible CPU utilization.
Putting the laptop back to sleep (closing the lid and waiting for the fan to stop) resolves the issue. When I re-open the lid, the fans stay off and performance returns to normal.
I’m not 100% certain, but it does seem to happen slightly more often in warmer environments.
Me too. Current workaround is to close the lid again until the fan switches off, then open the lid again and then everything is fine. This is annoying though so any fix appreciated!

Can confirm I have this problem as well, Librem 13 v 3.
On the assumption that this might be a firmware issue, and noting that my firmware was a little out of date (4.7-Purism-4), I followed the instructions here to update (to 4.8.1-Purism-2). Sadly that didn’t fix it.
I had the same issue. For me updating from coreboot 4.7-Purism-4 to 4.8.1-Purism-2 helped a lot.
Before the update the CPU dropping down to 400 and the fan going full speed happened after almost every wake up from sleep. And I had to power off and reboot.
After the update it only happens very rarely (about 1 in 20 times so far) and if it does all I have to do is close the lid, wait for the fans to stop and open the lid again.
Same here, about 5% of the time.
Finally back from my extended trip. The problem is still there after upgrading to
coreboot 4.8.1-Purism-3; cannot yet confirm the ‘statistics’ by others.
As far as I can tell,
this issue is spread over (at least) three threads; so I’ll link here to the other ones …

I would still hope that someone from puri.sm connects these threads and provides
official updates.
I can only report that I added the proprietory Intel firmware, but this had no effect on
the frozen frequency / fan full blast issue.
Best,
Stefan

I still have the same issue as well.
It seems to happen ~90% of the time when I’ve put my laptop to sleep while plugged in.
boot.log contains:
[FAILED] Failed to start Power/battery optimisations for Purism devices.
See ‘systemctl status purism-power-optimisations.service’ for details.
coreboot 4.8.1-Purism-3. Also ran an apt-get full-upgrade this morning and am running kernel 4.17.0-3-amd64
Issue still happens. CPU is slow (seems limited), and fan goes full speed.
Anecdotally it seems to happen more when the power adapter is plugged in than when just on battery, but it still happens in both scenarios.
Putting the laptop back to sleep and waking again resolves the issue every time.
Does anyone have a workaround? Any update from Purism on this issue?
Thanks!

I also can confirm these symptoms.
CPU throttled, full fan operation. Closing the lid (sleep) solves it about the same time the LCD back light turns off. Waking up to normal operation.
4.15.0-33
I still get the issue but I think that’s bc the components need time to warm up (physically) as after a while when it’s not so cold it works fine
I have had this issue in the past on my Librem 15v3, but it seemed to resolve itself over time. (I was probably closing the lid and didn’t realize that was the solution.) I haven’t had the issue in awhile, but it happened again today and found this thread after a reboot did not resolve the issue. When I ran systemctl status purism-power-optimisations.service, it showed an active status, so there was nothing more to do there. I was happy to find this thread with the suggestion to close the lid but I’m hopeful that the Librem team will figure out another solution to this.
Have the same issue. If sombedy know what service or kernel part is responsible for that thing I can take a look on code.
I also still have the full-fan-after-sleep issue after upgrading the coreboot to coreboot-4.8.1-7-g30300027ce-4.8.1-Purism-3.
Is there an official bug for this issue?
So it’s August 2019 and I’ve been through multiple Ubuntu versions on my Librem 13 version 2 laptop, currently running Ubuntu 19.04. All of these versions (18.04, 18.10, 19.04) for at least the past year have had this problem where perhaps 10% of the times that I open the laptop and rouse it from sleep, the fan starts blowing at top speed and the operating system behaves very sluggishly. It only stops when I completely power it down; a restart is not sufficient.
Am I the only one still affected by this? Has anyone found a solution in the past year?
I just received my laptop this week as well. Librem 15v4 and so far the fan has gone crazy like yours but I just figured it was because I was running a Virtual Machine in Gnome Boxes. (My poor ears…that noise is annoying)
Biggest issue is that after the first reboot Lux was broken claiming too many bad password attempts.
Did all the stuff you will find in the forum. Waiting on my Key and PureOS usb to reimage. Hopefully it works. I will likely tinker for a bit with this OS as I do like it however, I just need things to be encrypted and work so I will likely switch to Parrot OS or Trisquel until I receive the rest of my order to try and fix this.
Growing pains of wanting a linux laptop I suppose. At least we are all in this together so they may resolve these issues more quickly. I wonder if v2 or v3 is experiencing the same issues though.
Update before hitting reply…the Fan appears to have just shut off…Thank you NSA 
Other than that I like the form factor, keyboard, weight, wish it were white or silver so that it would not make collecting my fingerprints super easy.
Currently hunting for PureOS hardening guide. So far found a Debian How To but this Distro is growing on me.

I am affected by this from day one (Librem 13v3, a bit over a year old now). I am running PureOS, keeping it updated, and updating the firmware regularly. Nothing seems to make a difference.
That being said, it now happens much less frequently than during the first weeks.
I still don’t use the laptop regularly, in part because of the fan issue. I did use it constantly during a conference trip for a week, and the fan acted up exactly once.
Good luck,
Stefan
