Paso 1 — Battery

Use a coin or spudger to rotate thebattery-locking screw 90 degreesclockwise.

Paso 2

Lift the battery out of the computer.



Paso 3 — Memory Cover

Unscrew the three evenly-spacedPhillips screws from along the rearwall of the battery compartment.

The screws are captive to the metalmemory cover so you cannot losethem.

Paso 4

Rotate the L-shaped memory coverso it clears the battery compartmentopening and lift it up and out of thecomputer.



Paso 5 — Upper Case

Remove the following 3 screws:

One 11 mm Phillips#00 in themiddle of the case. (Head: 5mmdia. x .75mm thick)

Two 14.5 mm Phillips #00 (Head:5mm dia. x .75mm thick)

If the screws stick in the case, youcan use a magnetized screwdriver todraw them out.

The shorter of the three screwsgoes in the middle.

Paso 6

Remove the following 3 screws fromthe rear wall of the batterycompartment:

One 3 mm Phillips #0. (Head:2.75 mm. dia.)

Two 4 mm Phillips #0 on theeither side. (Head: 2.75mm dia.)

Take extra caution with thesescrews as they can strip easily.



Paso 7

Remove the two Phillips screwsfrom either side of the right wall ofthe battery compartment (not theones closest to the batteryconnector).

Two 6.25 mm Phillips #000.(Head: 4 mm. dia. x .5mm thick)

Paso 8

Remove the four indicated Phillipsscrews from the front wall of thebattery compartment. When workingfrom the left, remove the 2nd, 4th,7th and 9th screw.

Four 3.25 mm Phillips #000.(Head: 4 mm. dia. x 4mm thick)



Paso 9

Remove the following 4 screws fromthe back of the computer:

The longer screws go on the inside,shorter screws on the outside.

Two 11 mm Phillips #00, withShank (2.2mm dia. x 2 mm len.)(Head: 3.2 mm. dia. x .5mm thick)

Two 7.25 mm Phillips #00, withShank (2mm dia. x 3.75 mm len.)(Head: 3.2 mm. dia. x .5mm thick)

Paso 10

Remove the two Phillips screwsfrom the optical drive side of thecomputer.

Two 5.2 mm Phillips #00, withShank (2.3mm dia. x 3.5 mm len.)(Head: 3.2 mm. dia. x .5mm thick)

It is not necessary to remove thesimilar screws on the other side ofthe computer.



Paso 11

There's a trackpad and keyboardribbon connecting the upper case tothe logic board, so don't pull theupper case off entirely just yet.

Starting near the display andworking around to the front of thecomputer, pry up on the upper case.A plastic opening tool or a mediumhard guitar pick may help you to dothis.

The upper case is likely to stick atthe connection above the opticaldrive. If this is the case, first free allother sides, then proceed to pullupward on the upper case fromeither side of the optical driveopening.

If you stand the base on end to get abetter look you may displace thetotal of 4 grey plastic clips that holdthe keyboard in place. Don't panic.They slide into slots at the top right-most edge near the CD drive.

Paso 12

While holding up the upper case, pull up the black tab of the silver cable away from its connector.

If there is no black tab, you can also use a spudger to gently pry the connector from its housing.This connector is tall, so be sure to pry straight up.

If you happen to break your upper case cable when removing the upper case, we stock the cableindividually and we have a guide that makes replacing it easy.

While you have the upper case removed, you may want to take the opportunity to remove dust,hair, etc. It's best to use a can of compressed air, though if you use a brush, make sure that itsbristles are made of a material (usually animal hair) that doesn't generate static electricity, whichcan destroy electronics.

Upon reassembly, there are 4 grey plastic clips on the optical drive side of the keyboard (refer tosecond picture). They must be installed in their slots for the keyboard to snap in properly.

To make the reassamble process easier, it's better to pull out the clips first by pulling it straight upgently. Be careful not to put too much strength because it will break.

Paso 13 — Left I/O Frame

Disconnect the MagSafe boardcable from the logic board by pullingthe snap-in connector out (to theright).

Paso 14

Remove the single 9 mm Phillipsscrew securing the left speaker tothe lower case.

Lift the left speaker out of its housingand set it to the side.



Paso 15


Two 7.5 mm Phillips from eitherend of the left I/O frame.

One 9 mm Phillips from themiddle of the left I/O frame.

Remove the small black plasticspacer at the bottom of the left I/Oframe.

Paso 16

Lift the left I/O frame up and out ofthe computer. Pay attention to thethin metal EMI fingers, as they maycatch as you remove the left I/Oframe.

The speaker wire may be hookedonto the I/O frame. Lift it out of thecatch and don't forget to put it backwhen you are reversing theprocedure.

The part of the shield you areremoving is attached to other part bylittle hooks underneath that are hardto see until you have it apart.They're located over the headphonejack and the firewire port.



Paso 17 — Logic Board

Peel up the foil tape between the fanand the optical drive.

Paso 18

Use a spudger to move the graydisplay data and black speakercables to the right. This will reveal asilver screw securing the fanhousing to the lower case.



Paso 19

Disconnect the orange optical driveribbon cable from the logic board.

Paso 20

Peel up the small black rubber coverfrom the right side of the heat sink.



Paso 21

Disconnect the black fan connector and two temperature sensor connectors from the logic boardby pulling/prying up.

If you have a MacBook Core 2 Duo Santa Rosa/Penryn/Early 2009, there is only one temperaturesensor.

The heat sink in early 2009 MacBooks may look slightly different.



Paso 22


One 3 mm Phillips on the right side of the fan.

One 6 mm Phillips on the left side of the fan.

Four 9 mm Phillips securing the heat sink to the lower case.

Paso 23

Hold the heat sink with one handand the fan with your other hand,and lift the heat sink and fanassembly out of the computer. Thefan is attached to the heat sink onlywith a strip of black felt tape, so besure to remove both parts as a unit.

If you need to mount the heat sinkback into the laptop, we have athermal paste guide that makesreplacing the thermal compoundeasy.

If you have a MacBook Core 2 Duo Santa Rosa/Penryn/Early 2009, there are only two antennacables and the black inverter cable is in a different location.

Paso 25

Remove the following 2 screws fromthe Airport card:

One 3 mm Phillips from the leftside.

One 8 mm (with a large 2 mmhead) Phillips from the right side.



Paso 26

Grasp the Airport card at its top andslide it toward the screen and out ofthe computer.

Paso 27

Use a spudger to disconnect the leftspeaker connector from the logicboard.

Lift the left speaker out of thecomputer.



Paso 28

Disconnect the display data cable bypulling up on the black plastic pull-tab. If there is no pull-tab on the topof the connector, it may be helpful touse a spudger to disconnect thisconnector.

Paso 29

Disconnect the newly-revealed harddrive cable from the logic board.



Paso 30

Use a spudger to disconnect the speaker connector and bluetooth connector from the logic board.

If you have a MacBook Core 2 Duo Santa Rosa/Penryn, disconnect the PRAM battery cable.

Paso 31

Use a spudger to carefullydisconnect the microphone cablefrom the logic board. You'll want towork from side to side, and slowlywiggle the connector out of itssocket.



Paso 32

Deroute the microphone cable fromthe silver metal clip just above theright RAM slot.

This metal clip may not be presenton some Santa Rosa/Penrynmodels.

Paso 33

Use a spudger to carefully pry thebattery connector up and disconnectit from the logic board.
