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). -Kenny -- Kenneth R.
