is this on XO-1? if not, then i don't know how that would change
anything. if so, then you should know that doing this probably causes
the wlan to stay powered (and it wakes almost 1W!) when the lid is
closed or you've used the power button to put the laptop to sleep. a
resume script would be a better solution, if it works.
