BTW, apparently this was a Dell BIOS bug- they'd released version 1.6.2 a
couple of weeks ago for my machine (XPS 7390 2-in-1) and I haven't seen it
since. Considering this thing's a year old, I'm not confident in Dell's
ability to be proactive about bugs (but I guess in their defense that did
solve the the last issue I had with this thing).
