Adding extra memory to your system is one of the easiest internal upgrades that you can perform on any computer. If you simply don't want to mess with your Mac's internal organs, your local Macintosh service specialist will be happy to install new RAM modules for you (for a price).
Follow these steps to add extra memory to a MacBook or MacBook Pro:
1. Get ready to operate.
• Spread a clean towel on a stable work surface, such as your kitchen table.
• The towel helps protect your screen from scratches.
• Find a Phillips screwdriver.
• Shut down your laptop and wait at least 10 minutes for it to cool.
• Unplug all cables from the computer.
2. Close the computer and flip it over on top of the towel.
3. Ground yourself!
Your body can carry enough static electricity to damage the circuitry and chips that make up the brains of your Mac, so ground yourself first by touching a metal surface for a few seconds before you dig in.
4. Remove the battery.
Slide both of the release latches up to pop out the battery, and then lift it out.
5. Remove the two screws that hold the memory door closed.
Place the two screws in a handy plastic bowl for safekeeping. Here's your chance to gaze with rapt fascination at a portion of the bare innards of your favorite computer.
6. Locate the memory modules in your Mac's svelte chassis.
7. If you're replacing an existing memory module, remove it.
To remove a memory module, gently spread the two tabs at the ends of the socket apart (as shown in Figure 1) and then lift and slide the module away from the socket.
Save the old module in the static-free packaging that held the new module. Your old RAM will be protected from static electricity.
8. Position the new module in the socket.
• Line up the module's gold connectors toward the socket, at a 25-degree angle.
• Line up the notch in the module with the matching spacer in the socket.
• This is shown in Figure 2.
9. Press gently (but firmly) on both ends of the module until the module's tabs click into place on both ends of the socket.
10. Replace the memory door and battery.
