Question Battery slowly drains when plugged in; Won't run on just AC power

I have a Lenovo G50-80 (model 80L0) Notebook. When it is both plugged in and powered on, the battery will slowly drain until it dies. I get a "Plugged in, not charging" message from the Lenovo power management tool.

When I turn off the laptop and plug it, it can charge very slowly. I can get up to a full charge this way, then use it off battery power.

Of note, the laptop will NOT boot while it is both plugged in and has the battery removed. When I try this, the keyboard lights up and the disk drive initializes, but nothing comes on screen, then it shuts down.

I have tried two different chargers now, both of which are from Lenovo. Both of them push 45W, 20V @ 2.25A. I have updated all my drivers, updated the BIOS... no dice.

My laptop took a bad fall while plugged in and this has been happening ever since. I successfully repaired the damaged DC-in port (ordered a new one from this product page), but the charging issue still happens, so I have no reason to suspect that my repair caused the problem.

Any suggestions? I would go straight to buying a new battery, but the fact that I can't power it on without the battery makes me suspect that that's not the issue.
