The laptops can enter a special standby mode that keeps the network alive, so they will immediately resume when the lid opens. This means, of course, that the laptops never actually shut down and run constantly.
true, but i actually turn that explicitly off on physical network settings in windows.
My guess is windows will apparently not let u control such things, as the advertising data pipe has to be alive no matter what. Microsft seems to be both google and apple at the same time, selling ads and hardware.
