Hi, after dropping my thinkpad, the battery got slightly messed up. I have to move a battery pin to have it fit in the slot, the battery charging status is often not read by Linux, and sometimes power won't be received even without the battery. I'm hoping the solution would just be figuring out how to remove the pin stuck in the motherboard slot (attempts so far have evaded me) and getting a new battery, but what does it look like to you? Thanks!
A new battery has fixed the issues. I found the battery pins were pushed in, which messed up the connection. I'm still not sure why the OEM charger does not work, but at least a 3rd party one does.
