DELL XPS 13 (2017) - BATTERY ISSUE

I bought an XPS 13 last year and was working all fine till now. I turned on my computer during class and the front led light starting flashing. One orange, one white, which means its not a "supported battery" or something like that. I went into the bios and saw that it stated that the battery was not "a dell battery." Which makes no sense as I haven't ever replaced or done anything to the battery. Now, because it says it not a dell battery, it won't allow charge. I rely on this computer for school and this issue is a huge problem for me.
These are the steps I've taken so far to alleviate the issue:

- Checked if the AC adapter was the issue - AC adapter is shown in BIOS as 45w, so not the issue.

- Updated BIOS to newest version, no fix.

- Removed the battery connector, pressed and held the power button for about 15s, connected the battery back in, still no fix.

- Removed the battery and powered just from AC adapter, worked fine - further evidence that the AC adapter is not the issue.

- Can't run diagnostics as it fails in the battery testing portion.

I have no idea what to do next. The battery works fine as it boots me into windows and such, but if I try to plug it in, it just states "plugged in, not charging." I only had that 1 year warranty on this computer and sadly it expired like a week ago. Great timing! 

I would like to reiterate that this battery has not been touch and is the original battery that came with my computer when I purchased it last year. I have no idea what caused this issue as I did nothing different. Any help would be great!
