[SOLVED] Dell Inspiron n5110 Battery Recognized, not charging/discharg

Device: Dell Inspiron n5110
Purchase Year: 2012
Kernel: 4.20.10-arch1-1-ARCH
Battery Model: W7H3N06
AC Adapt Model: SK90195334

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. 

Upower reports:

    technology:          lithium-ion
    icon-name:          'battery-full-charging-symbolic'

The battery is a replacement, extended battery, and according to every utility I could think of 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?

Had a friend order me a new battery off of Amazon.  So I'll see if this is a battery issue or something more serious.

One person on the Dell Community Forums confirmed my suspicions that this is a burnt out battery.

Another suggested I flash a BIOS update, even if the BIOS is latest version. O.o

Definitely fried the battery. Odd that it showed 100% health but was fried.

Purchasing a new battery fixed the problem. Marked thread as solved.
