Introduction

If your display is broken or damaged you will need to replace the entire display.

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

    • Turn the computer over and open the display. You should see that the keyboard is loose.

    • 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.

    • 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.

    I did find that, strictly speaking, you don’t need to remove the ribbons. If you carefully hold up the keyboard up towards the screen with one hand, you can remove the old RAM and install the new one with the other. I suppose you could also use a length of masking tape to hold the keyboard up.

    I found it easier not to remove the ribbon, especially as I couldn’t find my plastic opening tool.

    • Disconnect the wires from the port.

    Speaker panel? I don’t think this is correct - I accidently pulled the black & red wires out from this part and sound still worked fine. Is this instead a battery connection?

Note that the side panels should be placed back BEFORE the audio panel.
