A tiny cylindric magnet taped to the back of the LCD trips a sensor under
the palmrest. The two LCDs I have (one from a 400, the other from a 550)
had the magnets in different places so presumably the sensors are
differently placed as well. I bet your replacement screen came from a
different model than your's and so the magnet no longer lines up with the
sensor.
Looking at the back of the LCD with the top edge up, the magnet location
relative to the upper LH corner:
400 - right 4 3/4" and down 1 1/4"
550 - right 7 3/4" and down 2 3/4"
Those positions of course can also be located on the palmrest ('Book open
and facing you) measured from the near righthand corner, left and toward
the back. You can trigger sleep with the lid open by placing a magnet
there. Heck if you _didn't_ have an exact location you could just slide a
magnet around the palmrest until the 'Book nods off. If you can't make it
go to sleep with a magnet, you've got a different problem.
And finally, a _BIG_ congrats on successfully getting it all back
together! I've now taken apart every Apple portable up to the TiBook and
clamshell iBook, and the TiBook was far and away the biggest PITA on
which to work. As you mention, the _entire_ thing has to come apart to
remove the display. Geez!! The good news is you can pretty easily re-open
the display to reposition the magnet without needing to remove the
display assembly from the 'Book. I hope you haven't glued it back
together yet though . . .
hth,
