my switch just died brehs. it stopped charging, tried different adapters -- didnt work. wont even turn on anymore. looked it up online and read a few experienced the same thing.
sent it back to nintendo for repair or replaced, cost me $99 since its out of warranty.
This literally happened to my coworker a couple weeks back.
So one night at work, using the switch as usual. He stopped playing, the next night at work he turns it on low battery and it's blinking (you know when it's about to turn off). He plugs it in, about an hour later completely dead.
I try my cords, don't work, his cord ain't working on mine. He sent it to nintendo and they replaced for free. He lost all the data.
The power strip he was plugged into surged and fried his shyt. The power cord, and the switch.
If your cord ain't working on other devices or someone else's switch that's probably what happened.
