I’ve found that dell laptops don’t sleep when unplugged from a dock in clamshell mode with an external monitor.

It was pleasant to find when I’d left work to the airport after unplugging it and stuffing it my bag, that the closed computer was burning up and at critical battery.

Now MS/dell Claims that’s a feature not a bug and that they’ve expanded the situations where that occurs. What are they smoking? Oh yeah burning laptop fumes
