See if you can warranty exploit the switch first. They give replacement items, but it is much more difficult to be honest.

What’s the best technique for a warranty claim? Appreciate any advice you can offer.

Yeah I second this, I’d love to know

Get a SN, tell them that it won't power on, they create a ticket for you and you mail them a box. Wait a few days and ask when you'll be getting your replacement. Goodluck.
