@DigitalCash by your name “digital cash”, are you thinking about Monero or you have some other favorite currency?
having experienced this issue myself, and seeing some talk of it on Purism’s matrix channels, I believe this is a known issue. The way I understand it, is the laptop, doing some sort of load, requests/requires more power than the battery is set to provide, and the Intel CPU completely shuts off the laptop. This is possibly related to the open source EC that the LIbrem14 is running, and I am hoping they are able to update it and fix this problem soon. Maybe @MrChromebox or @nicole.faerber can correct my inaccuracies and provide us with an update!
Monero is presently the only cryptocurrency with the attributes and adoption which allow it to be used as digital cash. I am very happy that Purism accepts Monero for all of its products.
I have not yet had time to see if the issue is heat related, but if the issue is a known problem with the power and EC then I’ll be interested to know more.
Update: I experienced another crash at 40% battery. There was no excessive heat, but the fans were whirring very loudly considering the laptop was not under heavy load. In fact, at the time I was only browsing this forum.
Which Matrix channels should I be lurking in to read these conversations?
I have the exact same issue, also mentioned it in my post here: [L14 Battery] Constant discharge + Charge in Qubes
In general if the kernel decides the box is too hot because of a temperature sensor reading, it will log something useful to /var/log/syslog (or wherever PureOS puts the main log, haven’t received my L14 yet so don’t know) before shutting down. Or it should anyway. You might check that file to see if there’s anything correlated with the time of crash.
can you tell me your firmware version?
sudo dmidecode | grep -m 1 Version:
Thanks for the advice. I will check this log immediately after rebooting the next time this happens.
Incidentally, I’ve found the fans have calmed down a lot since I ended the tracker-extract search indexing process. However, this was only shown as using 8% of the CPU so the issue will probably return.
Can you also tell me the version of the EC firmware that you have:
- Download the tool,
Open a terminal in the same directory where you downloaded the files. Or move the files to the home folder and just open a terminal. And extract the files from the zipped folders you downloaded:
- Run the terminal command:
gzip -d purism_ectool.gz
Make the update tool purism_ectool executable:
- Run the command:
sudo chmod +x purism_ectool
sudo ./purism_ectool info
It should read:
It would seem it is an older version than the example you gave. Here is my output:
On the Librem 5 it looks like there is no
/var/log/syslog file. I just posted a separate question about that:
I’ve had the inverse of this happen twice now - plugging in the USB-C charger to the USB-C right side port without the charger being plugged in to the wall resulted in an immediate crash. Running Pureboot 18 and EC version 2021-05-25_3b5ef1e.
Do you know how to get rid of this annoying stuff? I have the same problem, too.
Well, looks like I’m at least not alone with this =)… Just received my shiny new L14 today and dipping my toes into having a full linux workhorse (fed up with Apple…and Windows is even worse), problem is, it already rebooted randomly twice in the 6 hours I’m having it…it is quite warm today (maybe around 30°C/86°F), but wasn’t doing anything that would even remotely create any load on the system…and sadly writing this from my mac (again…) as I’m now worried that the L14 reboots in the middle of me writing this…
I just did a PureBoot BIOS update to v18 (the latest one) due to the headphone jack issue, but the first crash happened on the version it was delivered with, second one with the new version, so that doesn’t seem to make a difference.
Hope this gets fixed soon, can’t really rely on a machine if it randomly turns off without any warning and I would most certainly lose work & data.
PS: Don’t worry, not giving up that quickly on the L14, but a non-working headphone jack and random crashes/shutdowns are probably not to be considered the “ideal” experience for people to get into Purism/Linux
PPS: That’s acutally interesting, had it charged to about 86% at first (before turning it on the first time), but the used it unplugged ever since, means yes, the crashes happened unplugged, so I’ll now keep it plugged in and will report back if it crashes again! Will also do the BIOS/EC version extraction @joao.azevedo suggested and report back
Update: Erm, actually unable to boot, for some reason the L14 BIOS/System or whatever clock the LibremKey & PureBoot use was reset to 0 (e.g. 1/1/1970) which then causes the key verification to fail, says something in the line of “invalid signature, key was created in the future” or something alike, of course, it was created today =), but system thinks its 1970 now… it will only boot into the recovery shell… will try to turn HOTP verification off…which works, so I can get into the system, but now without the proper checks, which kinda defeats the purpose…
You can use the date command to reset the clock to the correct time:
From the recovery shell do:
date -s '2021-07-13 16:53:00'
adjust day and hour minutes and second to your timezone
and then run the command:
And then reboot
thx @joao.azevedo that fixed it, now able to boot with the librem key again!
Little Update, just had another crash after more than a day without any, although most of the time was spent ON the power brick, until maybe 1-2 hours ago when I unplugged it, then it crashes in a spectacular fashion, have a look:
Press power button for a few seconds, device turns off, then start again and hope nothing broke =)…so far it didn’t. When I plugged it back in (before restarting it, now knowing this is def. the problem) it started charging at 51%. Enviroment temp. def. not an issue today as it is cool.
So based on my experience so far I can confirm that this happens only when unplugged (like OP stated in the title)
@joao.azevedo I did run the purism_ectool, here’s the output:
board: purism/librem_14 version: 2021-05-25_3b5ef1e
Firmware version is:
Here is what I found right before the crash in

not sure if it is of any help… no idea what
RLIMIT_NICE not set means =)
btw, I also had to use this command I found somewhere in the forums to make the laptop even charge, otherwise it would just pull power from the plug, but not charge (e.g. battery would stay at whatever % charge it was plugged in):
echo '70' | sudo tee -a /sys/class/power_supply/BAT0/charge_control_start_threshold
I also see that there is a new EC version here: https://source.puri.sm/firmware/releases/-/commit/a27df1bb0220e33c918034a1dc0312c5f080e194#6d777e3978752766b2b98e999f4714dd6f8ab934
but how to update it, anywhere I can find instructions?
I do see that the ectool does have a flash function, but don’t want to brick anything, so help would be appreciated=):
SUBCOMMANDS: console fan flash flash_backup help Prints this message or the help of the given subcommand(s) info keymap led_color led_mode led_save led_value matrix print
EDIT: Well, went the danger-route and did what’s discussed here [librem 14] how to update EC firmware to ec-2021-06-04_ef9fd3c
Didn’t brick my L14 either, so I did simply
sudo ./purism_ectool flash_backup ec-2021-06-04_ef9fd3c.rom
but maybe don’t try it at home, if not urgent, wait for official “release” and instructions, but I need to travel monday and can’t really rely on a machine that crashes when unplugged…so hoping that the EC update will help, don’t know yet, will report back!
sudo ./purism_ectool info shows
board: purism/librem_14 version: 2021-06-04_ef9fd3c
UPDATE: Unfortunately bad news, laptop still crashes after EC update, although I managed to run it down to 15% this time, not sure if the charge percentage is relevant though.
that EC update does not address the crash when unplugging/crash when below 50% battery and under heavy load. The update is for that is forthcoming.
