Product View
General Information
Overview
The MacBook Pro (15-inch 2.4/2.2GHz) is the third generation in Apple’s line of Intel-based
professional notebook computers. Based on a newer and more robust Intel Core 2 Duo chip, the
architecture supports faster clock speeds, now extended to a new CTO option of 2.6GHz, and
increases bus speeds to 800 MHz. Speed aside, the new system now addresses up to a full 4 GB of
DDR2 memory and sports a new on-board graphics chip: the NVIDIA GeForce 8600M GT.
The MacBook Pro (15-inch 2.4/2.2GHz) also introduces a new LED-driven, power-ecient display
backlight (the industry’s rst 15-inch) rather than using uorescent tube backlighting, eliminating
mercury from the display. Apple recently announced this technology publicly as part a new
corporate directive toward a “Greener Apple.”
From the exterior, the MacBook Pro (15-inch 2.4/2.2GHz) is identical in appearance to the previous
MacBook Pro (15-inch Core 2 Duo).

Main service and feature differences among 15-inch MacBook Pro models:
NOTE: On November 1, 2007 a new 2.6GHz CTO (congure to order) option was added to the line
of MacBook Pro (15-inch 2.4/2.2GHz) models. In addition, two previous CTO hard drive options
(200GB, 4200 rp m and 160GB, 7200 rp m) were upgraded to faster and larger capacity hard drives
(250GB, 5400 rpm and 200GB 7200 rp m).
However, despite conguration changes all service procedures remain the same. See exploded
views in the Views chapter for new part numbers.

New Parts and Procedures
Main Logic Board
The main logic board of the MacBook Pro (15-inch 2.4/2.2GHz) has a third thermal sensor
connector near the left fan. This thermal sensor is attached to the bottom case.
Memory
The maximum supported amount of memory is 4 GB rather than 3 GB.
LED Backlight LCD Panel
The new LED backlit LCD panel can be easily identied in a couple ways. The display driver board
is now at the bottom of the panel instead of the top. The LVDS cable no longer travels up the
back of the display. In addition, the LED power is integrated into this cable.
This technology allows for a continuous backlight from the moment power is applied. Previously,
the uorescent tube required a warm-up period to reach operating brightness. Not only does
MacBook Pro (15-inch 2.4/2.2GHz) Basics— General Information 8
LED technology eliminate all mercury from the display, but also LEDs weigh less and provide
Correct Insertion Incorrect InsertionCorrect Insertion Incorrect Insertion
more brightness for the equivalent amount of power.
It is very important that the video ex connection to the LCD panel be properly inserted, aligned
and seated in its connector on the panel. Misalignment can cause multiple video issues. During
insertion, the connector should be perfectly straight, not at an angle, and the connector should
slide into its mate in a at position, parallel to the LCD panel, not obliquely. See illustration below.
Keyboard
The side tabs on the upper right and left of the keyboard have been removed. The keyboard
drops right into the keyboard well rather than having to bend the corners to t in each side tab.
To compensate for the removal of the corner tabs, two screws have been added to the bottom.
ExpressCard Cage
The ExpressCard cage enclosure has multiple perforations in the metal to cut down on weight
and materials. In addition, “pocket screws” now secure the cage to the left I/O board. These larger
headed screws make contact with EMI gaskets on the bottom case for improved noise isolation.
Temperature Concerns
The customer may perceive this system to run hotter than previous models. However, the normal
operating temperature is well within national and international safety standards. Still, customers
may be concerned about the heat generated by their machine. To prevent an unnecessary repair,
you can compare a customer’s computer to a running model, if available, at your repair site.
For more information on temperature concerns and customer perception, refer to Knowledge
Base article 30612: Apple Notebooks: Operating Temperature.
Display Takeapart
With the MacBook Pro (15-inch 2.4/2.2GHz), we still utilize the whole display clamshell as a service
part. However, some parts are accessible by the removal of the display rear housing.
Specically, a Service Provider can replace:
Display hooks • Sleep magnet•
Display housing • Camera board•
All other parts including the LVDS cable are serviced with the whole clamshell module.

Service Manual Note
In this manual, graphics or photos are intended to help illustrate procedures or information only,
and may show dierent levels of disassembly, board colors, congurations, or computer models,
than your computer.
Kapton® Tape Note
Kapton tape is used to secure cables and connectors where necessary.
During disassembly, note any Kapton tape use and locations—reapply in the same manner. Do
not over apply or build up tape on top of old tape; space tolerances are tight and build up or
extraneous use of tape may cause pressure on other components.
Cable Routing Note
With the MacBook Pro’s one-inch enclosure height, the placement of parts and wiring is critical.
During disassembly, note cable routing. Reassemble in the same manner. Verify that cables do
not route over components when they should route into lower positions or channels. Verify that
the cables are not strained or applying pressure onto other components.
Screw Measurement Note
All screw measurements given are the specied full length. Actual measured lengths may vary.

Latch Adjustment
Overview
To secure the display to the top case, the MacBook Pro uses a latch assembly that consists of two
parts—a latch mechanism under the top case (actually attached to the bottom case frame) and
two swinging latch hooks inside the display assembly clamshell. As the unit is closed, magnets
inside the latch mechanism pull the metal latch hooks down into the bottom case, and an
overhang on the latch mechanism clasps the hooks to the frame.
If the display does not properly latch to the top case, fails to remain closed, or pops up without
the display release button being pushed, you can make adjustments to the latch hooks that may
correct the issue. Alternately, you can send the computer to an Apple Repair Center for service.
Tools
This procedure requires the following tools:
Black stick (or other non-marring nylon or plastic pointed tool)•
Magnet•
Preliminary Steps
Warning: While performing the following procedures, take note of the position of the hooks
as they are drawn out of the display housing and down into the slots in the top case. Any
adjustments to these hooks must be very slight to stay within the slot on the top case.
Before performing the latch adjustment, test the current operation of the latches:
Push the display down to about two inches from the top case. Then push the display very 1.
slowly until it just touches the top case, and immediately release.
If working properly, the latches should secure the display to the top case throughout the
following tests:
Pounding rmly on the table top, to the left and right of the computer.•
Pulling up on the sides of the display.•
Repeat the above procedures several times to verify proper operation of the latches.
Whether or not the latches functioned properly during testing, use the following procedures 2.
to achieve or to verify proper latching function.
MacBook Pro (15-inch 2.4/2.2GHz) Adjustments — Display Latch 14
Procedure
Note: The latch mechanism under the top case of the computer has a small amount of right and
left play (less than 1 mm), and can shift during normal operation.
The following procedures will test the latching function with the latch mechanism at its
maximum right and left positions, and the latch hooks will be very slightly adjusted, as necessary.
Important: The latch hook metal can become brittle and break if it is bent too much, especially
if it is over-bent and bent back. Work carefully and with due restraint to avoid over-bending the
latch hook. If the latch hook breaks, new latch hooks will need to be ordered and replaced.
Open the display and note the edges of the latch mechanism underneath the top case, 1.
shown below, just to the right and left of the latch release button. This mechanism catches
both left and right latch hooks on the display assembly.
Use a black stick to push the latch mechanism, at the location shown below, to move it to 2.
the left as needed (less than 1 mm) or its corresponding location on the left side of the latch
release button to move it right (less than 1 mm).
MacBook Pro (15-inch 2.4/2.2GHz) Adjustments — Display Latch 15
Perform the testing procedures in step 1 of the Preliminary Steps, above.3.
If the latch functions properly, skip to step 6; otherwise, if either or both latch hooks require 4.
an adjustment, refer to the following steps.
If the latch mechanism does not function properly, adjust the latch hook(s) as follows:5.
Open the display to a 90-degree angle and use a magnet to draw the latch hook out. Tightly
grasp it between your thumb and forenger as close to the display as possible, as shown.
Carefully exert a very slight controlled downward pressure on the latch hook.
Important: Do not push only with your thumb. Hold the latch hook tightly between your
thumb and forenger to support the latch hook and prevent too much bending force.
Release the latch hook, adjust the other latch hook as needed, and perform the latch tests as 6.
before. Continue the above procedure until both latches function properly.
Again, if needed, use a black stick to push on the latch mechanism, as shown below, to adjust 7.
it slightly left or right (no more than 1 mm) or to re-center the mechanism over the latch
release button.
Repeat the previous latch closing tests, and latch hook adjustment if needed, until the latch 8.
works properly in this position.

Face the computer toward you with the display open slightly past 90-degrees. Using your 6.
ngernails or the tips of your ngers, grasp just beneath the top case in the upper right and
left corners. Lift upward a few inches, then work your hands around the top case toward the
front, slowly lifting and encouraging the clips and screw tabs to release. A snapping noise
when the clips release is normal.
Note: Take care to preserve the cosmetic integrity of the plastic beading around the edges of the
top case. If using a black stick for leverage to get the clips to release, don’t rotate the stick too
much along the edges to avoid denting the soft plastic.
MacBook Pro (15-inch 2.4/2.2GHz) Take Apart — Top Case 28
Along the front, start at the left and slowly encourage the snaps and screw tabs (shown in 7.
graphic below) to release as you move right. A snapping noise as the snaps release is normal.
Again, take care to preserve the cosmetic integrity of the plastic beading around the edges
by pulling up with your ngernails rst. If a black stick is necessary to release the snaps, avoid
too much rotation along the edges to keep from denting the soft plastic.
Important: Do not lift the case once it is free—it is still connected to the bottom case by the
keyboard ex cable.
