So the latest update got me Debian 10.10 on my Novena. Thanks! (you know who you are)

Is there any chance of getting Debian 11 on the Novena?

This issue has been fixed now.

Yes, need to get my Novena to boot again, then I'm going to try this.

That is useful. Thanks!

Ok, do I need to worry about the discharge (C) rating? Or is "same or higher" good enough?
(batteries on HobbyKing sure do get out of stock quickly)

ok, the original battery was out of stock, and the suggested replacement too.
This one might work?
https://hobbyking.com/en_us/turnigy-nan … wxt60.html
Physically a bit smaller, and the connector is different but other than that it looks compatible to my untrained eye.
Any reasons why it would not work?

Congrats on the 5 year anniversary!

My Novena still works too, but the battery is gone, and I would like to buy a new one.
Unfortunately, it says "International shipping not available for this item" (probably because of regulations).
And I live in Norway.

Is there an option for buying a battery on this side of the big pond?

So I had trouble booting my Novena laptop with the same symptom as in the boot time problem: stream of systemd[1]: Time has been changed thread.

1) How do you know  if the power source below the DIMM is a supercap or a reachargeable battery? mine looks exactly like the one in the PVT2 top picture, green color an all, but there isn't any markings on the top side of it. Anyway, when the Novena is powered off it reads about 0.3 V. The DIMM covers it, so I can't measure the voltage when the machine is powered on.

2) I figured out that if I disconnect the main battery plug  (the large 4 pin Molex plug) the Novena boots fine, without any symptoms.

3) How is the battery charged? Through the main connector or through the smaller (balancing?) connector?

4) is it dangerous or wrong to plug in the main battery connector while the Novena is running?

5) Is it dangerous to run the Novena with the main battery connector disconnected?

Very nice. Which batteries do you use?

Next up, I tried to reset things:

ch> gg pfreset
Resetting permanent failure flags... Error: 1000000
ch> gg reboot
Rebooting the gas gauge chip... Error: FE000000
ch> gg it
Starting ImpedenceTrackTM algorithm... Error: 0xFE000000

So is my senoko board broken?

Update: I left the battery disconnected for a few days (busy with other things), it still reads 12.1 volts with a multimeter.
After connecting it, I tried stats again:

Ok, so I finally found time for this again. I disconnected the battery (molex, then taps). After havin done that, I ran 'upower -d' and got

Huh? I checked - the battery is still disconnected.
Is it supposed to behave this way?

Ok. And when you reconnect a battery you do it in reverse order (taps, then molex)?
Never mind - I see now that you write "reconnect...taps, then molex" in your message.

Your symptoms (unable to get the machine to draw power from the battery) seems to be like the ones I am having, see the thread here: https://www.kosagi.com/forums/viewtopic.php?id=420

I haven't tried to disconnect the battery yet, but I might try it now.
How long did you disconnect it for? Just a moment, or a longer timeframe?

Is this "jumpstarting" procedure described somewhere? (my Novena is currently running of AC, since the batteri doesn't work the way it is supposed to).

I just had a thought: am I supposed to disconnect the battery when doing pfreset or any of the other commands?
I haven't done that - the battery has been connected the whole time.

Ok, I tried  the 'gg pfreset' command:

ch> gg pfreset
Resetting permanent failure flags... ok.

But it didn't seem to have any effect, stats still says:

that didn't help either, stats still says "Permanent failure condition".
Anything else I can do?

Well, the problem is that it will not charge as it is (it has been connected to a charger for several days now). Given that it says "permanent failure" I think I will have to issue a pfreset command. But I'm no expert on this.
Questions:
a) is it safe to issue a pfreset command?
b) do I need additional commands, or will the pfreset command work on its own?

FWIW, it is easy to get the firmware version if your SSD is working:

Yes, and the odd things in the output is one of the reasons why I am worried. Hopefully I will get some advice in this thread.

Ok, so I have a Novena laptop, from the Crowd Supply crowdfunding.
Now the battery doesn't charge (the laptop dies when I remove the charger).

Is this anything I can fix with some of the "magic" commands in the battery threads in this forum?
Or should I get a new battery?
I'm a bit worried about it saying battery failure, but  all three cells looks like the voltage is ok.
