Nintendo switch won't boot unless plugged into PC

This is a v2 switch that doesn't have any mods installed. My usb voltage reader is showing normal readings. If I try to plug it into the OEM charger, it won't respond or show a charging icon. Pressing the power button will make the nintendo logo appear but then it's a black screen after that. Docking won't do anything, either.

The strange part is that it will boot up if I connect it to my PC with a usb cable. It's booting up fine and able to run. I just don't know what is happening. With my limited knowledge, I can only assume it has something to do with the lower voltage of the usb from the PC.

I've already tested and replaced the m92 and USB port and the diode readings for those seem fine. The diode readings on the BQ chip are also fine, but I still suspect there could always be an issue regardless. Perhaps even a faulty m92 chip that was used (I've read the replacement ones can be faulty).

Running out of options here. Any advice is appreciated.
