System will restart out of sleep mode, but only when the charger is unplugged. Running an XPS 13 9350. Recently installed the following updates to Windows 10:
Thinking of rolling back the anniversary edition updates, but I wanted to check for support first.
EDIT: To the best of my knowledge, hardware/software is completely updated:
OS: 10.0.14393 Build 14393
BIOS: 1.4.4, 6/14/2016
Chipset updated via Dell Update, etc, etc
Turns out that I didn't have the latest BIOS version. Dell doesn't always increment the revision number in their BIOS builds, so you have to go by the date. In this case, I had v1.4.4 June '16, but there was a July revision.
All is well, now.
