Lenovo T470s: Second battery not charging

I switched to Fedora 40 from Linux Mint recently; the latter got it working with tlp but with Fedora about nothing seems to help. With “tlp fullcharge” “tlp-stats” gives:

Absolutely happens with the second battery whatever I attempt to get.

I’ve stumbled across T470s firmware updates in the desktop’s software app (I’m a command-line user) but that didn’t change nothing. :frowning: This is a get-away-from-Fedora-again issue, I’m afraid.

The support of yours here is marvellous! I mean it. Guess I’ll have to live with this issue until I can get my hands on a new machine or an external battery.

I also use a T470s and don’t have a problem with charging both batteries. However both are replacement batteries and not the original ones any more.

So you had the primary battery soldered out, didn’t you? Because if not I might take the same road.

Both were “removable”, i.e. attached to the mainboard by screws, not soldered

That’s why I still prefer to ask the experts face to face instead of looking online. Had whole other info on that. Thanks a bunch!

I am by no means an “expert”. I bought the laptop second hand and while it was working fine, it would randomly shut down when running on battery. So I opened it, and saw that one battery was severely bloated and the other a bit. So I looked online on how to replace them :wink:

I basically followed the videos on the Lenovo site:
