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 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 (Core 2 Duo).

New Parts and Procedures
Main Logic Board
The main logic board of the MacBook Pro (15-inch 2.4/2.2GHz) now 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 now 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
LED technology eliminate all mercury from the display, but also LEDs weigh less and provide
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.
MacBook Pro (15-inch 2.4/2.2GHz) Basics— General Information 7
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 been modied with 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.

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
The MacBook Pro matches the same one-inch enclosure height established with the PowerBook
G4 17-inch series of systems. More so than ever, 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
If the display latches do not secure the display to the top case, or if they release before the
latch release button is pushed, an adjustment to the latch hooks can be made to correct this.
Alternately, the computer can be sent to the Apple Repair Center for service.
The display latches consists of a latch mechanism under the top case (it’s actually attached to
the bottom case frame) and two pivoting latch hooks within the display assembly. The hooks are
pulled down into the latch mechanism by a magnet as they approach the top case, and they are
secured under an overhang on the latch mechanism.
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, notice the hooks as they are drawn out
of the display housing and into the slots in the top case. If adjustments to either latch hook are
performed later, they must be adjusted only very slightly, 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 multiple times to verify proper operation of the latches.
Whether or not the latches functioned properly, use the following procedures to achieve or 2.
to verify proper latching function.
MacBook Pro (15-inch 2.4/2.2GHz) Adjustments — Display Latch 13
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 optimum
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 hooks. If a 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, by pushing from 2.
the right to move it to left as needed (less than 1 mm), or conversely, from the 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 14
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 below.
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
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 move 6.
it to the left or right (about 1 mm) 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 7.
works properly in this position.
