Tape the thermal sensor cable to the display assembly to avoid getting it trapped under the 
1.  
logic board and forgetting it during reassembly. Important: Do not tape over connectors 
with exposed contacts. Residual adhesive from the tape can contaminate the contacts.  
Remove the thirteen Torx T6 screws, shown. 
2.  
Warning: Do NOT allow the logic board to flex at any time. Flexing the board can crack 
3. 
solder joints to components. Give special attention at the narrow neck of the fan cutout.

From the left side of the board, slowly begin to lift the board, avoiding any flexing, until the 
4.  
thermal material on the three chips underneath releases.  
Note: The thermal material should easily release. If not, verify that all screws and connectors 
have been removed 
Be sure to insert the black stick between the logic board and the plastic shield on the 
5. 
bottom case below. Avoid lifting from under the plastic shield.

Note the lip on the right speaker that overhangs the logic board. Be sure to lift the logic 
6.  
board with the speaker before separating to keep the logic board from bending. 
Carefully lift the left side of the board, supporting the board along its sides as it lifts, and 
7.  
pivot along the ports side as you finesse it clear of the port openings..

After lifting the logic board clear of the bottom case, separate the speaker from the logic 
8.  
board by sliding it directly down to clear the lip on the speaker enclosure.
Remove the logic board.
9. 
Important: In the MacBook Pro (17-inch Core 2 Duo) only, there are two metal shims either 
on the under side of the logic board or on the heatsink heatpipes near the graphics chip 
(see location callouts below). If reusing this logic board, make sure those shims retain their 
position above the heat sink posts .

Method 2
Disconnect the ten cables shown. (Note: some of the cable connectors in the MacBook Pro 
1.  
(17-inch Core 2 Duo, 2.4GHz and Early 2008) may be JST connectors, not pictured below.) 
Tape the thermal sensor cable to the display assembly to avoid getting it trapped under the

logic board and forgetting it during reassembly. Important: Do not tape over connectors 
with exposed contacts. Residual adhesive from the tape can contaminate the contacts.

Remove the twelve Torx T6 screws, shown. Two screws that secure the fan to the frame are 
3. 
indicated below under the LVDS cable.  
Warning: Do NOT allow the logic board to flex at any time. Flexing the board can crack 
4.  
solder joints to components. Give special attention at the narrow neck of the fan cutout. 
Use a black stick under the extension of the heatsink, just below the rear of the left fan, then 
5. 
slowly begin to lift the board, avoiding any flexing.  
Note: The the logic board and heatsink assembly, along with the fans, should easily lift up. If 
not, verify that all the appropriate screws and connectors have been removed.

Note the lip on the right speaker that overhangs the logic board. Be sure to lift the assembly 
6.  
with the speaker before separating to keep the logic board from bending. 
Support the assembly as it lifts, and pivot up and away from the ports as you finesse it clear 
7.  
of the port openings. (Unlike the photo below, keep the speaker attached to the assembly.)
After lifting the logic board clear of the bottom case, separate the speaker from the logic 
8.  
board by sliding it directly down to clear the lip on the speaker enclosure. Remove assembly.

Replacement Procedure
Verify that the EMI gaskets are in place along the port openings on the bottom case. 
1.  
If replacing the logic board, transfer the two screw guides, called sleeves, along top edge of 
2.  
the board.  
 
 
Important: There are two metal shims on the under side of the logic board near the  
graphics chip. (See screws #4 and #5 in the screw replacement order in step 14, following.) 
Make sure those shims retain their position above the heat sink posts when replacing.

Warning: 
3.   If the logic board was removed to facilitate another procedure and will 
be reinstalled, the existing thermal grease cannot be left on the board and must be 
completely cleaned off, since it will create a thermal barrier if combined with new grease.  
Use the following procedures to clean off the old thermal grease—or overheating and 
damage can result.
U
4.   se a black stick to remove the grease from the mating surfaces of the three chips.  
Important: Use extreme care not to damage the chips or logic board components.
Use alcohol wipes to completely clean the grease from the surfaces and surrounding area.  
5. 
 
•  Install EMI gaskets and tape on the ports from the gasket kit.

• 
Transfer the cosmetic shield, if needed.  
•  Transfer the battery cable and the left I/O board cable 
 
Warning: Used/existing thermal grease cannot be reused and must be completely 
cleaned off, since it will create a thermal barrier if combined with new grease.  
Use the following procedures to clean off the old thermal grease, and then to reinstall 
new thermal grease—or overheating and damage can result.
Use a black stick to remove the 
6.   thermal grease from the three mating surfaces.
Use
7.    alcohol wipes to completely clean the grease from the surfaces and surrounding area.  
 
 
Warning: Whenever the logic board is separated from the heatsink, the thermal grease must
