8.
edge of the battery bay near where the RAM slots are located:

• Two identical 3-mm long screws

• One longer 4.5-mm long screw at the corner of the battery bay nearest the battery
connector

Because this is a recessed area, the screwdriver has to go in at an angle. Keep the screwdriver
in line with the screw head as much as possible.
Replacement Caution: When installing these three screws, an incorrect installation could
cause the reassembled computer to wobble in use. To prevent a wobble symptom, use light
pressure to hold the top case onto the assembly when installing the screws.

Warning: Whenever the heatsink is separated from the logic board (even if you are
installing the same heatsink or board), the thermal grease must be completely removed and
replaced. Failure to do so can cause the computer to overheat and be damaged.

With the heatsink removed, use a black stick to remove as much thermal grease as possible

1.
from the two chips on the logic board and the two pads on the heatsink.

Use an alcohol wipe to completely clean the residual thermal grease from the two chips. (If

2.
you are replacing the logic board with a new one, skip this step.)

Important: Use extreme care not to damage the logic board components.

MacBook (13-inch) Take Apart 61

Use an alcohol wipe to completely clean the two pads on the heatsink.

3.

Using the syringe, put a 0.15 to 0.175 cc dab of thermal grease, in the center, on the mating

4.
surfaces of both chips, as shown below.
Important: One syringe (922-7144) contains 0.3 to 0.35 cubic centimeters (cc) of thermal
grease. That is enough for 0.15 to 0.175 cc of grease for each chip. Use half of the syringe

contents per chip. You might nd it helpful to use a felt-tip pen to mark the half-way point
on the syringe before applying the rst dab. Then you can empty the rest of the syringe

contents on the remaining chip. Although the amount shown appears to be plenty of grease,
this is the correct amount that has been tested and veried on the production line.

Important: Avoid unnecessary contact with new thermal material, as dirt and body oils
reduce the material’s conductivity.

While centering the heatsink pads over the two chips, lower the heatsink onto the logic

5.

board and press on the areas where the screw brackets on the heatsink meet the standos

on the board. Make sure the heatsink is level on the board before installing the screws.

Install the heatsink, and reassemble and test the computer.
