I'm sorry to hear that. Clearly, a dead device is a hardware issue. If it is under warranty, MS usually replaces things quickly & easily. I've had several Surface devices replaced over the years -- the most recent was my out of warranty Surface Pro 3, which cost me $300 to replace when it developed power issues (wouldn't boot, then when I finally got it to boot, it shut down randomly, frequently, and would just randomly restart).
Do you realize that this is a Surface Book forum & thread you're posting in? There's a whole section of Windows Central's forums for the Surface 2 here:
