Shitty, an internal battery? I understand the fear. It's very easy to short something when getting in there so I understand the apprehension. I tried with my last laptop to replace a memory module when the diagnostics diagnosed that one of the RAM were failing and successfully replaced it. Unfortunately, the same issue popped up a couple weeks later making it a motherboard issue and that was a wasted piece of RAM.I had read about that and the shop suggested I do that first when I called last night so I undid the screws and started popping the laptop keyboard cover off slowly while watching a YT vid on how to do it correctly and I chickened out as I have a tendency to make things worse when I take shit apart .
No its not powered by USB-C, its your run of the mill 1/2" long or so round aux input.
Probably best to just try the power source and hope that's all it is. If it makes you feel better, I've blown 2 laptop power sources, a couple batteries and 3 desktop power sources in my time owning computers. Every other failed component doesn't add up to the number of failures I've seen related to just power sources, so I think the odds are in your favor and if you do need to do the battery it's not crazy difficult.
Second most failed component for me is Video Cards which happened twice. Motherboards twices, once when it was only 13 months old (yup out of warranty). One hard drive and one memory module.
