My Wii U had been finicky with turning on, a lot of times it had to do with the AC Adapter being in an awkward position, and it took a bit of moving around to fix. Now no moving around works and there is no red light indicating it has power. I swapped AC Adapters, to no avail, I also replaced the 3V CR 2032 Battery. I'm planning on cracking open my Wii U because I'm pretty sure this indicates an internal issue, any tips on how to solve this?
