Replacing a Chip in a MacBook

Install modules with matching memory for best performance.

The MacBook has a 2GB base memory and a maximum capacity of 4GB, with the ability to hold two memory modules. Unlike other Apple products such as the iPod Touch, which requires a nearly complete teardown to upgrade the memory, replacing the memory chips in a MacBook requires minimal labor and only one tool. When you do it yourself, replacing the memory in your MacBook does not void Apple’s limited warranty.

Things You'll Need

• Lint-free or microfiber cloth
• Phillips screwdriver, #00

Instructions

1. Power down your MacBook and allow 10 minutes for the internal components to cool. Disconnect all cables attached to the MacBook.

2. Position the MacBook face-down on a lint-free or microfiber cloth. Remove the eight screws from the back of the MacBook case using a #00 Phillips screwdriver.

3. Grasp the rear case on the hinged side, remove it and set it aside. Touch a bare metal surface in the MacBook with a finger to discharge any static electricity in your body before continuing.

4. Press the ejection levers on the memory module outward. After the memory chip pops up, look for the half-circle notches, indicating it is ready for release. If you don’t see the notches, press the ejection levers again.

5. Grasp the memory chip by the half-circle notches and remove it from its slot by pulling it straight out. Do not handle the gold connectors when removing the memory module.

6. Align the replacement memory chip’s gold edge with the notch in the lower memory slot. Push the module into the slot, using firm, unilateral pressure. If you plan to install another memory chip in the top slot, repeat the memory insertion steps described above. Both modules should be parallel.

7. Reinstall the rear case on the MacBook and secure it with the eight screws using the #00 Phillips screwdriver.
