Switch Pro Controller not powering on
I was using my pro controller on both my PC and my Switch interchangeably, when, after using it on PC specifically, it decided to no longer power on. No signs of life when I hit any button on the controller - no lights, nothing when I press and hold the sync button, and no charging light when plugged in directly to the AC adapter.
I have, at the behest of forum posts, ordered a new, third party battery and replaced the old one with no change. The controller still does not power on.
I am considering taking the controller apart and attempting to diagnose the issue. I have read about using a multimeter (something I have not done before), but can anyone give me a few simple steps to try to do a full diagnosis?
At this point I’m treating this like a learning experience, not desperate for a 100% guaranteed repair to the hardware, but if it’s possible to fix it, I would like to.
