I've run my Lombard closed with linux for an hour at a time with no
trouble. I just kill pmud and close it. I usually turn my backlight
all the way down first...
I was unaware of any temperature management in MacOS (I thought it was
controlled in hardware), but if it exists i'd be interested in
implementing something to control it. I'd like to be able to turn my fan
on at a lower temperature then is the hardware default. Do you know
anything about the interface to such things?
