    • 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.

To reattach the keyboard I found it necessary to keep the kid open and push the keyboard all the way down; otherwise, the screws didn’t engage.
