No Power to Battery

Hello all.

I picked up a Kobo Forma off of Ebay for cheap; the charging port was pulverized and I figured it would be an easy fix. After replacing the charger port, I tried plugging it in to charge, but even with leaving it on the connector over night, it didn't come up. Checked the voltage on the battery and had nothing at all. Removed the battery from the circuit and tested the pads with the charger cord in, and only saw 0.063VDC, so something in the circuit isn't reaching the battery.

Does anyone have any idea what to check from here? I tried looking online, and I can't seem to find any board layouts for this Forma. It's an 8GB model if that helps; I can't seem to find the actual model number on the unit.
