[L14 Battery] Constant discharge + Charge in Qubes

@MrChromebox have you been able to replicate my described situation? For the record I have had no issues with PureOS.

@fbk no I haven’t had a chance to do any testing under Qubes recently. But working on an EC update that may address the underlying issue.

Thanks for letting me know I’ll be waiting for news.

Any idea what the cause of this might be with Qubes?

Power barrel jack is physically plugged in, but yet, status file reports Discharging and charge_now continues to increase:

I’m experiencing same type of behavior. One weird thing is that energy-full-desing for me is also only 52,8Wh even though it should be 66,8Wh

Thanks for posting your own experiences people. Good to hear I’m not the only one experiencing battery/charging issues with the L14 in Qubes

Same issue with preinstalled PureOS (not showing full battery capacity).

The weird battery behavior I have been seeing in Qubes 4.0.4 only occurs after the first suspend, and seems related to all ACPI events no longer occuring. If I reboot, everything works fine. For example:

  1. From a powered down state, power on.
  2. xfce4-power-manager and upowerd all handle un/plugging the charger properly. The battery percentage seems to make sense. The Fn+F5 and Fn+F6 keys work properly to change the screen brightness.
  3. Close the laptop lid which triggers a suspend.
  4. Open the laptop lid. The laptop stays suspended. Press the power button, the laptop resumes from suspend to the login screen.
  5. Notice that xfce4-power-manager and upowerd no longer handle un/plugging the charger properly. The Fn+F5 and Fn+F6 keys no longer work.
  6. Reboot, back to behavior at #1.

I’m wondering if this is a problem with the embedded controller. I don’t know if getting the librem-ec-acpi-dkms driver installed would resolve this problem. I gave it a go but ran into problems trying to get it built for Fedora-25 (what dom0 is using).

Related output from journalctl -b | grep --ignore-case "acpi":

Jun 29 18:23:21 dom0 kernel: ACPI: EC: event unblocked

Related Arch Linux bug (0 and 1) describing the same behavior, root cause was a problem with the proprietary Samsung embedded controller: “The problem is that Samsung’s embedded controller stops sending GPE events if it still is waiting for previous GPE events to be queried from it.”

I can confirm that installing the librem_ec_acpi DKMS driver resolved the above problems. My guess is the bugs mentioned above, where the embedded controller gets into a stuck state, is what was happening. Nicole’s driver handles all ACPI notifications (see librem_ec_notify method). It would be nice if this driver made it to the upstream kernel particularly if the laptop is going to be marketed as the “best qubes laptop”.

For others, I used the following commands from dom0 (I tried to build a package to be copied and installed from dom0 using a fedora-25 template but ran into problem after problem so I went the direct DKMS route):

$ sudo qubes-dom0-update kernel-devel dkms gcc
$
$ sudo mkdir /usr/src/librem_ec_acpi-1.0.0 
$
$ # Create the following file with the contents below
$ sudo vim /usr/src/librem_ec_acpi-1.0.0/dkms.conf 
PACKAGE_NAME="librem_ec_acpi"
PACKAGE_VERSION="1.0.0"
BUILT_MODULE_NAME[0]="librem_ec_acpi"
DEST_MODULE_LOCATION[0]="/extra/"
AUTOINSTALL="yes"
$
$ sudo vim /usr/src/librem_ec_acpi-1.0.0/Makefile
obj-m                       += librem_ec_acpi.o

clean:
	rm -f *.o *.ko *~
	rm -f .librem_ec_acpi.* *.mod.c Module.symvers modules.order
	rm -fr .tmp_versions
	rm -f Makefile.xen

$
$ sudo dkms build librem_ec_acpi/1.0.0
$
$ sudo dkms install librem_ec_acpi/1.0.0

Thanks for the instructions, I managed to follow and install the DKMS and now /sys/class/power_supply/BAT0/ has all the same entries as showed off in the post.

However, even after multiple restarts it still exhibits the same behavior as before unfortunately. Not sure why.

Edit:
Even after setting charge thresholds (to 60/80 for example) it still likes to start charging at 98%.

Edit2:
It appears that XFCE Power manager might just not like updating. Also these thresholds appear to be need to be set on boot everytime.

One thing that I have noticed is that battery led doesn’t indicate charging when xfce4 power manager notifies that battery is charging. This is without setting charge threshold

Hi leaningtress,

could you help me. I followed your instructions but when I build it gives me:

Error! echo
Your kernel headers for kernel 5.4.98-1.fc25.qubes.x86_64 cannout be found at /lib/modules/5.4.98-1.fc25.qubes.86_64/build or /lib/modules/5.4.98-1.fc25.qubes.x86_64/source.

I got it working under PureOS by installing the kernel-headers. However, on Qubes kernel-headers and kernel-devel are already installed.
Do you know what to do?

The issue seems to be that the kernel and the kernel-devel package don’t fit together:

dnf list installed kernel-devel kernel-headers kernel
kernel.x86_64 1000:5.4.98-1.fc25.qubes @anaconda
kernel-devel.x86_64 1000:5.4.125-1.fc25.qubes @qubes-dom0-cached
kernel-headers.x86_64 4.13.16-100.fc25 @qubes-dom0-chached

Still don’t know what to do. I have tried uninstall and reinstalling, still no difference.

I’ve fixed my issues by:

sudo qubes-dom0-update kernel

Then installed it via Yum-Extender Gui

Then according to “dnf list installed kernel” I had the old and new one still installed. I did:

sudo qubes-dom0-update kernel-qubes-vm --best --allowerasing

which is most likely not necessary since it is for the VMs not dom0.
Then:

sudo dnf remove kernel-5.4.98

The next hurdle was that the build process failed. I figued I had to download librem_ec_acpi.c myself from the link and put it in /usr/src/librem_ec_acpo-1.0.0/librem_ec_acpi.c.
The reason probably is that I am using Sys-Whonix for updates so it did not download the file.

Thanks a lot leaningtrees, it works!!! :slight_smile:
I am really dumb I set the start threshold to 40 and my battery was at 70. Consequently, it did not charge. It just did what it was meant to do.

cat /sys/class/power_supply/BAT0/status

gives you “unknown” when the notebook is running on powerplug. The LED indicates the same with the white color. I think it is a bug of fce4-powermanager that is says charging, though the battery is not charging at all.
It gives you “charging”, when it is really charging and “discharging” when it is discharging.

Should I mark learningtrees’ answer as the solution? It seems to have helped a few people and fixes issues.

I have the following issues remaining after installing the DKMS driver to get it to charge (running Qubes):

  • Same issue as fbk where i get discharge-charge-discharge-charge while connected to power
  • Sometimes on power disconnect complete power off of the laptop. Not failing over to battery quick enough?
  • When suspended it drains the battery quite fast
  • Fans are going loud too often. Changing governor to powersave or disabling turbo mode results in no CPU scaling at all and a very slow laptop. Need to find some way to reduce aggressive CPU scaling without killing it completely.

When I attempt to adjust the start and end threshold with echo, I get a bash error that permission is denied. What am I doing wrong and how do I correct this?

May be you’re just missing sudo? And be sure to do it in dom0.

I have attempted using sudo with no change. I am admittedly a newbie to qubes and linux as a whole, so maybe I am missing something. As far as using dom0, should I be doing it a different way other than using the terminal emulator in the applications menu?

Everything else seem to have worked through there, and I get 100 and 0 for my start/stop threshold check.
