I recently got a Dell XPS 15 9570 (W10 Pro, i7, 16gb, 256gb, 1080p option) and I've been learning a lot about the sleep issues with modern standby. For many previous users, the laptop would overheat during sleep either due to bad wake timers, switching from sleep to hibernate, etc. The laptop would become active and stuck in a loop during sleep, often in a backpack or laptop case, and would operate at max CPU until overheating or the battery drained.
I recently had a similar issue, but with some twists. I pull my laptop out of my backpack and find it to be off, warm, and not turning on. I google it, find these issues, and assume I'm in the same boat. I plug in my laptop, wait 10 minutes or so for it to charge, but it's still not turning on. The charge light is on, but the power button does nothing. Eventually, I give up, and I close the lid (lid had been closed before while in the backpack). I hear in my bluetooth headphones "phone #2 disconnected." I immediately turn off my headphones, open the laptop back up, and hit the power button, and it immediately turns on.
Interesting bit: my battery was at 86%, much too high to have been dead, after my 10 minutes of charging. And my laptop, while warm, was not burning hot as some have described. I checked many of the causes others have listed previously, but dell seems to have fixed them by default - hibernate is always off, and wake timers aren't even an option anymore.
So it seems my bluetooth connection was the sole reason for my laptop's infinite loop? I've checked and bluetooth still works fine (as a note my headphones are weird about connecting to multiple devices, which may contribute to this issue). If anyone is having a similar issue, try turning off all bluetooth devices, and make sure to turn off bluetooth before sleep!
I will update if the issue happens again
