I got this Switch with the fault described as the console not working in the dock. When testing it I found that it worked perfectly in handheld mode, but indeed did not connect to the dock, either for charging or for display out.
When I connected a charge cable I found that the console will only charge with the cable in one way round - insert it one way, the console charges as normal; turn the cable around and nothing. I assume that’s why it won’t work in the dock - that must require it to be the “faulty” way around, and obviously I can’t put it in the dock the other way so no way to test that.
The charge port looks intact, but I’m not ruling that out. What else could be the cause of this?
