Help being pointed in the right direction on switch repairs

Could it be a dead battery?
Also, I like this site:
https://www.ifixit.com/Device/Nintendo_Switch
It has guides for all parts.

 

From what I've seen no amps being drawn is a bad BQ24193, bad fuse (although I've yet to see this) or bad battery. You can have a dead cpu and the switch should still charge normally.

 

It's just above the usb-c port, it looks like a black resistor.

 

I don't know what you would have had in your laptop days but if it is anything like I am seeing for apple's junk with full signals level stuff you need a capture scope to usefully detect then I have not seen anything like that in consoles... probably ever if I don't count the Amiga and similar devices. Some older devices do slightly better and we have some sanded PCBs to look at, and some people have a few sub systems (mostly sound and graphics, maybe a test of test points to shove in an autofire) documented reasonably well or common caps to fail noted in a list but beyond that... you could probably advance the state of the scene dramatically by getting a working board and measuring the components on it (hope you have a nice ESR meter, or can be bothered to desolder things), and noting voltages at different power states.

Some people fired the parts cannon a few times so we have some fixes for bad docks and what have you that blow certain components a lot, most of which I imagine you have already seen, but again nothing resembling what I would expect in some kind of industrial setting, that I watch the likes of https://www.youtube.com/user/rossmanngroup/videos play with a lot or even something I would expect as a baseline 10 minute "worth repairing or not?" tester or "you just have to fit it and program it" mechanic. Even among those parts cannon fixes, and guides following from them, I would not give a good warranty if that was all I knew/did.

Did you ever get this figured out? Thank you
