Removal of the track pad panel is necessary to reach the hard drive and track pad.

Tools: Spudger; TR8 Torx Security Screwdriver

Step 1

• Close the screen and turn the PowerBook over, orienting the computer upside down, using the label to guide you.

Step 2

• Hold the button on the front left side and slide the battery out.

Step 3

• With a Torx T8 screwdriver, remove the three Torx 24mm screws along the center of the back panel.

Step 4

• Turn the computer over and open the display. You should see that the keyboard is loose.
• CAUTION: Before attempting to remove the keyboard, note that a ribbon cable connects the keyboard to the logic board. Improper removal may damage your keyboard.
• Slightly lift the front of the keyboard up, and slide the keyboard towards yourself.
• Carefully lift the top half of the keyboard and pull it towards yourself.

Step 5

• Loosen the ribbon cables connecting the keyboard to the computer by using a plastic opening tool to lift the tabs on either side of the cable port.
• Gently remove the ribbons from its tabs.

Step 6

• Gently wiggle the RAM card to loosen the connection until it pulls free.

Step 7

• Push the display screen back to give yourself enough space to remove the side panels.
• CAUTION: Before removing the side panels, note that removing the side panels hastily will damage the underlying panel screw. However, this will not affect the functionality of your PowerBook.
• Remove the panels on either side by gently but firmly pulling up on them with both hands.

Step 8

• Use the plastic opening tool to lift up the tabs on either side of the ribbon cable port and then gently pull the ribbon cable free.

Step 9

• CAUTION: WARNING: There is a high risk of breaking the tabs that lock the panel to the casing. Remove the panel slowly and cautiously to avoid damage.
• With your index finger and your thumb, squeeze the track pad panel to loosen the clamps. Then slide the panel towards yourself.
