We brought our Switch with its dock to my family’s place for Thanksgiving and it wouldn’t power the console or show on TV anymore. Brought it home and still no luck. Solution: replace off-brand AC adapter with official one! (I had lost it somewhere before)

@Burk I’m not sure, it was a while ago that I had to replace it. My wife did some research and found that it’s common for there to be issues with any unofficial power adapter. A software update happened shortly before it failed, so we figure that was the trigger.
