4. With the display open at an angle greater than 90 degrees, carefully flip the
PowerBook over and lay it flat, fully on the table. Make sure the display hangs over the
edge of the table and rests lightly on your lap (Figure 1B).
5. Slide the battery compartment latch (Figure 2A) to remove the battery (Figure 2B).
Make sure to return the battery latch fully to the right.
Removing the battery will help you remove the bottom case and prevent you from
accidentally turning on the computer.
6. Using a Phillips screwdriver, remove the eight screws that secure the bottom case to
the PowerBook, in the order shown (Figure 3).
Important: To avoid damaging the case, be careful that the screwdriver tip does not
slip out of the screw head during removal.
7. To remove the bottom case you will need to disengage it at the left and right sides,
then carefully pivot it forward to release a retaining clip near the DVD drive slot, as
follows.
Important: Do not push on the rubber feet of the bottom case.
At the left side, carefully slide the bottom case slightly up and away from you by
pushing on it just above the hinge of the display (Figure 4), and at the same time
from within the battery compartment, pushing away from you on the edge of the
bottom case, until the left side releases.
At the right side, again carefully slide the bottom case slightly up and away from you
by pushing it just above the hinge of the display (Figure 5), and at the same time
from within the battery compartment, pushing away from you at the right-most edge
of the bottom case, until the right side releases.
8. When both the left and right sides have released, carefully pull up on the bottom case
at the edge that is closest to you and rotate it away from you, pivoting evenly over the
front edge to release a retaining clip that is located near the DVD drive slot (Figure 6).
Important: Do not force, twist or pry the bottom case if it binds or resists. The case
should remove easily. If not, follow step 7 again, until the case releases.
9. Touch the computer’s inside framework (a dull gray conductive composite material) to
discharge any static electricity, as shown (Figure 7).
Important: To avoid electrostatic discharge damage, always ground yourself by
touching the computer’s framework before you touch any parts or install any
components inside the computer. To avoid static electricity building back up in your
body, do not walk around the room until you have completed the installation and
closed the computer.
