[Solved] X1 Carbon Gen 7 Battery Status recently Flappy

Hey All,

After my last update, the battery status indicator started being flappy.  Not sure if this is a hardware or driver issue, but both gnome and upower report 0% charge, when I know that to not be the case.

Occasionally it will jump up to 47% briefly, but then it will go back to 0% after a while.  Happens when both charging and on battery power.

09:23:55 $  upower -i `upower -e | grep 'BAT'`
  native-path:          BAT0
  vendor:               LGC
  model:                02DL004
  serial:               ABCD
  power supply:         yes
  updated:              Wed 12 Feb 2020 09:22:46 AM EST (69 seconds ago)

  has statistics:       yes
  battery
    present:             yes
    rechargeable:        yes
    state:               charging
    warning-level:       none
    energy:              0 Wh
    energy-empty:        0 Wh
    energy-full:         51.99 Wh
    energy-full-design:  51 Wh
    energy-rate:         0 W
    percentage:          0%
    capacity:            100%
    technology:          lithium-polymer
    icon-name:          'battery-caution-charging-symbolic'

Where should I be looking to debug this?  I believe it started happening after this upgrade:

Only thing that looks suspicious in that is the systemd upgrade, who's patch looks inconspicuous:

Running gnome with xorg and minimal patches / configuration changes to installed packages.

Going to attempt a firmware upgrade. :-)  It was naive of me to assume it was up-to-date.

Re: [Solved] X1 Carbon Gen 7 Battery Status recently Flappy

Update: attempting to update the firmware, even with the `--force` flag enabled for fwupdmgr, results in "Check power failure, please insert the power source or charge the battery" when the firmware update should be running on the terminal pre-POST.

Time to contact lenovo... :annoyed:

Re: [Solved] X1 Carbon Gen 7 Battery Status recently Flappy

Interestingly... Switching outlets in my house allowed the computer to start to charge a bit more, still with sporadic drops back to unknown battery state, but allowed me to get above 30% battery threshold for updating the firmware.  Will report back in a few days if it's fixed the issue.

Re: [Solved] X1 Carbon Gen 7 Battery Status recently Flappy

FYI I continued to have the issue and had to reseat the battery as in this thread:

https://forums.lenovo.com/t5/ThinkPad-X … 156?page=4

Seems to have worked for now.  Crossing my fingers it doesn't appear again and I don't have to do that often/ever again.

Hi citsuac, do you think you could give us a little more detail on exactly what procedure you followed to make it work? There are a lot of potential mentioned solutions in this thread

Thanks a lot!

Re: [Solved] X1 Carbon Gen 7 Battery Status recently Flappy

Ah, sorry I missed that reply tbw!

I opened the bottom of the laptop, unplugged the wire where the battery connects to the motherboard, plugged it back in and closed the panel again.

Unfortunately, with extreme disappointment, I came back to the thread to say that the issue recurred.

I'm going to try the solution again since it worked much longer than any other solution.

Here's a link to a video that demonstrates which wire I unplugged, and plugged back in: (linked to the exact time in the video)

If this works, it makes me think that they have some always-on software inside the battery itself that can somehow get corrupted and isn't possible to reset from inside the OS itself.

Re: [Solved] X1 Carbon Gen 7 Battery Status recently Flappy

The solution worked again until yesterday.  Whatever they've got going on, it's pretty bizarre.  Going to open up the laptop again and do the magic unplug/plug it in again incantation.

Re: [Solved] X1 Carbon Gen 7 Battery Status recently Flappy

This is also happening to my Gen 7. Strange how we have had the same problem at the same time which to me suggests perhaps some sort of kernel update

EDIT:

Just tried the disconnect reconnect battery trick. Appears to have fixed the problem for now.

Re: [Solved] X1 Carbon Gen 7 Battery Status recently Flappy

Same laptop, same issue here.
I had the issue some days ago then applied these steps:

No more issue so far.
