I have acquired a PowerBook G4/400 with a broken display, plus the display
to fix it.

I have found instruction on the web to replace the display, and have done
so. (At: http://homepage.mac.com/sysop/PhotoAlbum13.html)

However, when I was putting it back together I realized I had an extra part:
a small rare earth magnet, cylindrical in shape, about 3/16" in diameter,
and the same tall. All the magnets are present on the top side to hold the
keyboard in place, and I can find no locale immediately where it would seem
to go.

Can anyone here help me?

Does it work otherwise?

If so, don't worry.

Not sure about older G4 PBs but my new 12" AlBook has a magnet that
makes the latch spring out to catch when closing.

I was hoping to mention the spring-latch part!

Let me suggest something else: I don't think there is a switch in the
hinges, but something registers when the screen is closed. There may be
a magnetically-closed circuit for this almost anywhere around the edge.

Not very helpful, but it might be something to look for.

Actually, there is a smaller magnet taped to the back side of the display
for this purpose. From the rear, it is just right and above the Apple logo.

The magnetic latch works without the piece in question, but that would mean
it's next to the hard drive, and there's no room for it I can see, but
that's a thought.

On the Titanium series, there is a magnet on the right side of the
monitor about 2/3 the way down from the top. This triggers sleep on the
TiBook when you close the lid.

I discovered this one day when I dropped a paperclip which promptly
stuck to the monitor's edge. Putting a magnet on the base in the
opposing spot made it go to sleep.

I knew about the one in the display (the broken one had it, I saw). I had
thought of that, but didn't see a likely spot to secure it. Guess I'll have
to look again.

Transferring the location of the existing magnet on the back of the display
to the lower case, this would place the extra magnet just to the right of
the trackpad. In other words, inside the optical drive mechanism, which is
mostly ferrous metal; the magnet would NOT have been loose in the case, IMO.

SIGH.

might be glued. Why not check your broken monitor for the location?

? Doesn't sound right. I recall my TiBook having the sensor on the far
right side of the base somewhere around the speaker. I put a small
magnet over the spot and the TiBook promptly went to sleep.

Maybe this is a case where a picture is worth a thousand words:

BTW, if that last reply was not the magnet you were talking about, I
think there is a magnet in the base that pulls the hook in the lid down
when you close it. It always mysteriously lowers the hook on closing
and I don't think its a mechanical thing.

If it were glued, it wouldn't have been loose for me to find on the
countertop.

Now THIS idea I can use! I've noticed the sleep light doesn't come on when I
close the lid (though the display goes out, likely to the magnet on the back
of the display).

I'll give this a shot and report back!

This seems to be working OK, and _is_ magnetic.
