It happened to me when my Switch stopped charging and would not turn on. I have first changed adapters and cables, and nothing helped. Rather than sending it out on weeks I chose to find local repairs. As I was surfing through the Internet, I entered Nintendo Switch repair near me in the search box to find out which service centers existed in the vicinity with good ratings. I got a technician who found out that it was the faulty charging port and restored it within a day. It was also significantly cheaper than purchasing a new console and they even offered a limited warranty on the repair. My Switch has been working well and has been charging since then like new and without any other problems.
