I did replace my son's iBook hard disk this week. Upon disassembling it, I

Remembering previous problems with Wallstreet problems when replacing the
hard drive and how it affected the lid's switch, I think that the magnet is
used in the latch to activate some switch that tells the iBook it has to go
to sleep or to awake.

However, I haven't found any reference to this magnet in the PBFixIt
documentation.

Does anybody know exactly where this magnet go?


If the sensor is a good old fashioned reed switch this won't matter, 
but if it is a hall effect sensor (solid state) it may be sensitive 
to the magnet's polarity (North / South).  So try reversing the 
magnet.

Thanks. It's a G4 iBook. I'll check it out. If a picture is not too much of
a problem, I would appreciate if you had one.

Thanks again!

hacker: n. [originally, someone who makes furniture with an axe] 1. A person
who enjoys exploring the details of programmable systems and how to stretch
their capabilities, as opposed to most users, who prefer to learn only the
minimum necessary. 2. One who programs enthusiastically (even obsessively)
or who enjoys programming rather than just theorizing about programming. 3.
A person capable of appreciating hack value. 4. A person who is good at
programming quickly. 5. An expert at a particular program, or one who
frequently does work using it or on it; as in `a Unix hacker'. (Definitions
1 through 5 are correlated, and people who fit them congregate.) 6. An
expert or enthusiast of any kind. One might be an astronomy hacker, for
example. 7. One who enjoys the intellectual challenge of creatively
overcoming or circumventing limitations. 8. [deprecated] A malicious meddler
who tries to discover sensitive information by poking around. Hence
`password hacker', `network hacker'. The correct term for this sense is
cracker.

Same on a G3.

There is a second magnet for the latch.

In any of the all white iBooks there is a magnet around the release 
latch that attracts the hook out of the lid.  I just tested it and it 
seems like it must also operate the sleep sensor as the latch only 
just enters the hole when it goes to sleep.  It can sleep without the 
latch engaging mechanically.


So I'd say it has to go very close to the latch hole above the latch 
release button and near the trackpad button.  The magnetic field is 
centered about that hole.
