I guess battery just died…RIP.

Do you have tlp installed?
I had a similar problem sometimes on my previous laptop. The battery wasn’t dead but spent a long time starting to charge properly. The charge-percentage would not change for a while before it would start to slowly creep up.

I recommend trying to keep it plugged in and monitoring the battery charge, preferably with some decimal places. I use:
sudo tlp-stat -b
and am checking the value for charge (second from bottom).

I also had a problem where the battery indicator would stop working all of a sudden, but that is probably a Cinnamon issue :stuck_out_tongue: Hope that helps :smiley:

Some laptops do indeed offer a possibility to limit charging (often to something like 50-60%) in order to preserve the battery.
That can be useful if you work plugged-in a lot.

It’s just a wild guess, but maybe the update introduced something which recognized that mode for your laptop and activated it.
