Difficoltà

Moderate

Passi

Tempo Necessario

15 - 20 minuti

Introduzione

In order to access the display or replace any portion of the sound system you must first remove the speaker panel from the computer.

Strumenti

TR8 Torx Security Screwdriver

Passo 1

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

Passo 2

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

Passo 3

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

Passo 4

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.

Passo 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.

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.

Passo 6

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

Passo 7

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?
