In the other thread you've opened I've seen that the laptops is a Lenovo T480. Did you try the reset button ( there is a small hole hidden under the laptop)?
Yes, I've tried pressing the reset button , for even upto 20 seconds - but it hasn't changed much wrt the battery charging situation.
You can also try to discharge the static from your T480. If you haven't done that, it may fix the problem....
Ok, I haven't tried this - will try to do the steps, quick q's :
I guess I should also disable the internal battery first?
Will I have to disconnect the cable of the internal battery and plug it in back as well?
If "sysctl dev.battery.0.%desc" says "ACPI Control Method Battery", writing this to /boot/loader.conf should disable the battery driver on reboot:
debug.acpi.disabled="cmbat"
Yes, it does say "ACPI Control Method Battery" - do you mean I should append
Code:
debug.acpi.disabled="cmbat"
to the loader.conf and try turning on the laptop? Should I remove it later?
UPDATE : Tried this with the loader.conf having that value and starting the laptop - I couldn't query using acpiconf -i0/1 as expected - then restarted the laptop and removed the same line - it didn't have any effect on that charging situation - still stuck at 53% (5%, 79% respectively for internal,external batteries). So this seems like a dead-end?
How recently did this problem emerge, compared to when you tried setting the charge thresholds mentioned in your other thread, mid '23?
Thanks for noticing
- no I believe this is something that happened recently, maybe perhaps due to a bios/firmware update with ubuntu updates (on the 2nd disk) that I may have done - or perhaps before that - I'm not entirely sure what caused this, could have been from before the ubuntu update as well.
So please show those data from:
acpiconf -i0 and
acpiconf -i1
Sure, I still don't understand how 5% and 79% average out to be 53%
, but that's an explanation I can live without, for now :

Also, are you sure you're running the latest BIOS/ UEFI update from Lenovo? If not, flash the latest one (use Ventoy if no USB updater).
Actually after the ubuntu update (2nd hard drive) I've noticed this error at boot time
`(A7) Me FW Downgrade - Request MeSpiLock Failed` - not sure if it's related, but I suspect the timing of battery malfunction and this error are somewhat correlated - not that I think about it.
