Dell XPS 13 restarts when waking up from sleep on battery power

As of yesterday, if I put my Dell XPS 13 9350 (Windows 10) to sleep and wake it up again, it boots up from scratch, applications complain that they were forced to quit with unsaved files, etc.

It seems this specifically occurs if it is on battery power when I wake it up. (Incidentally I'm fairly sure it occurs whether I put it to sleep by closing the lid, using the power button, or using the Start menu. It also occurs if I hibernates instead of sleep, though I never do this so have only tested it once.)

I assume this is due to some update Dell Update made a couple of days ago, but I don't know what it was.

I've since updated drivers from the Dell site & elsewhere, uninstalled video drivers (which fixed this problem for someone else on this site), and specifically checked that the battery-related drivers are up to date, but none of this helped.

Any suggestions?
