Coulda swore I found a checkbox in a control panel someplace that simply
said "Don't sleep when cover is closed"... For the 5300 series, the
detection switch is inside the hole that the latch goes into, and taping
a card of some kind over the hole allows the cover to be mostly closed
and completely unaffect the sleep mechanism.

If there's vents in the top someplace. Many of the older PBs didn't have
vents or fans, so heat isn't a big issue; closing the cover didn't
affect much. Also, setting the processor to allow cycling down to a
minimum and letting the hard drive spin down keeps things VERY cool.
