Inspiron n5110 Battery Recognized, Not Charging/Discharging

Device: Dell Inspiron n5110

Purchase Year: 2012

OS: Arch Linux

I am having an issue that just presented itself last night. I was compiling a java program and it was taking quite a while, and the CPU usage was 100% for.. probably close to 10 minutes. The laptop was getting hot, the cpu fan spun up, I was preparing to kill the compile so it didn't overheat, and the laptop crashed. Immediate power-off.

I powered the system back on, everything is functioning correctly, but when i unplugged the AC adapter the laptop shut off. The battery is recognized and seen by the OS, and according to the OS it's 'charging'. But it's been at 75% since. It is not charging the battery, and it's apparently not using the battery either.

I rebooted the system, holding down the fn-key to boot into the diagnostic tool, ran the basic tests, and it claims the battery is fine, 100% health, 75% charge, charging.

The battery is a replacement, extended battery, and according to every utility I have to check it, the battery is functioning perfectly. The laptop recognizes the battery, but doesn't seem to want to use it as a power source.

I'm pretty certain this is due to the overheating that occurred last night.

So my concerns are, Did I fry something on the motherboard, Did i fry something in the battery, or is something else going on that I can't see? Does anybody have any suggestions or tips to help me figure this out?
