My friend returned his Surface Pro 4 a few days after he got it when a mandatory Windows update bricked it, as in it turned off instead of restarting, and wouldn't turn back on.
I had a similar problem with a Surface, but some persistent going through the reboot options (of which there are about six, in increasing order of nuke-it-from-orbit-it's-the-only-way-to-be-sure) fixed it eventually.
There were no reboot options. The damn thing wouldn't turn on. My friend now has an XPS13 (which he had for just over a year before an issue with the fan prompted him to return it to the retailer for repair; amusingly the retailer screwed that up and offered him a new one as a replacement).
