Remplacing an 15'' aluminium powerbook
As usual, I cannot be responsible for any damage to
your machines when you will experiment the following
Unplug the pwb and upturn it.
Remove the battery with the help of coin (half a turn to
unlock) and remove the two screws.
Next the 4 screws (B) which unlock the RAM door. And
still two screws (C).
Finally, the 4 screws (A) on the shell.
Caution: these screws has been sealed, so they can resist.
And when reassemblying the pwb, do not force on them. If
needed, clean their heads to remove the remain of sealt.
On the right side of the machine, 3 more screws.
Same on the left one.
On the rear, 4 screws: first remove the two ones
above..when the machine is not upturned (the ones closest to
Open the Powerbook and remove the bolts...
... on both sides.
Warning: protect first the screen. Then insert a plastic
spatula under the upper plate and turn the spatula of half a
turn to unhook the plate.
Do not lift up the plate too much to avoid damaging the
small clamps on the hided face of this plate.
So now... the most delicate step...
We have to unhook the lug which lies inside the machine
and which is only reachable through the DVD slot!
Here I use an "Allen" spanner, but it is easier with a
(PS: Andre, do you have a picture which zoom on such a
(Webmaster: sorry, no)
So: to unhook the lug, we have to introduce the hook on
the left side of the DVD slot and slightly pull. Please, do
this smoothly, with the hook the more vertically as
possible. It is rare that one can do this in the first
When this is done, there are a few lugs on the right to
be unhooked with the plastic spatula.
Once the plate removed, unplug the two ribbons which
connect the keyboard to the motherboard.
The first one by simply lifting it up, the second one has
to be unhooked.
Now we have to cut off on three sides the plastic which
cover..the 13 screws which lock the keyboard onto the plate
(Wemaster: personnally, I would unscrew them through the
(The author: yes, I test it but:
1. the screws are very tiny and unscrewing them through the
plastic sheet is not so easy
2. doing this can damage them... they are so tiny!
3. and when reassembling the keyboard, plastic parts can
fall in screws' holes)
Here are where those marvellous tiny screws are loacted
Do not forget any of them otherwise you will damage the
keyboard when extracting it.
When the keyboard is removed, we have to unhook the last
ribbon on the other side of the plate and which passes
through a slot in the rear part of the keyboard (blue arrow
on the picture below).
The red arrows show the stickers we have to removed
before inserting the new keyboard but which have NO TO BE
replaced by the ones included in the package. Because the
new ones are not transparent (great!) and will prevent the
keyboard backlighting to work properly.
The other ones are compulsory to fix the keyboard on its
Insert the keyboard exactly as shown on the picture:
first the lateral sides, then next apply an uniform pressure
on its whole face to move it down and to stick it on the new
replaced stickers..especially in the corners.
Do not forget, in the reassembling process, to put some
tape on the screws to avoid them to touch the motherboard
when the pwb will be closed.
So follow the instructions above in a reverse order to
rebuild the machine
And... yes... last but not least... do not force on the 4
screws on the lower part of the shell!
