General Information
Product View
Overview
Both the MacBook Pro (17-inch) and MacBook Pro (17-inch Core 2 Duo) represent the a new generation of MacBook Pro professional notebooks. The original MacBook Pro (17-inch) is built upon the Intel Core Duo chip, while the new MacBook Pro (17-inch Core 2 Duo) is based upon the more recent Intel Core 2 Duo chip, increasing processor speeds to 2.33GHz.
In comparing the MacBook Pro (both the 17-inch and the 17-inch Core 2 Duo) to the previous generation of 17 inch aluminum PowerBook G4s, they may have a similar look, but only the power cord and power adapter AC plug are the same.
The exterior of the new MacBook Pro (17-inch Core 2 Duo) differs from the preceding MacBook
Pro (17-inch) in one small but clever way. The LED for the iSight camera no longer depends on opening in the display bezel to be visible.
MacBook Pro (17-inch & 17-inch Core 2 Duo) Basics— General Information
Also new is a MagSafe Airline Adapter, available for both the MacBook Pro (all models) and the
MacBook (all models).The MagSafe Airline Adapter fits into the EmPower port nearest your airline seat. Some airlines may have 20 mm in-seat ports that require the use of an additional adapter (included in the kit).

New Parts and Procedures
This section not only compares the new MacBook Pro (17-inch Core 2 Duo) to the previous MacBook Pro (17-inch), but as a combined manual for both MacBook Pro 17-inch models, it may also reiterate how they differ from previous PowerBook G4 17-inch models. Unless specified, comments can be applied to both 17-inch MacBook Pro models.
Main Logic Board
The hallmark of the MacBook Pro (17-inch) and MacBook Pro (17-inch Core 2 Duo) is the Intel Core Duo and Core 2 Duo chip, respectively, each with a ATI Mobility Radeon x1600 graphics chip. The microprocessor is soldered to the main logic board. It is not upgradable.
All ports in both MacBook Pro 17-inch models remain the same.The port differences between the
MacBook Pro and the PowerBook G4 include: the MagSafe power port and second USB port on the left, as well as ExpressCard/34 replacing what was previously a PCMCIA card slot. The security lock slot is on the right side of the system. Due to all the port re-arrangements, the new logic boards will not fit in any Macintosh 17-inch PowerBook G4s or vice versa. Composite and S-video connections are now only available using an optional Apple DVI to Video adapter.
The boot architecture of the MacBook Pro is based on Extensible Firmware Interface (EFI), replacing Open Firmware (OF) of PowerBook G4 days. Boot snag keys such as “C” for boot from the optical drive,“N” for network boot, and “T” for Target Disk Mode stay the same under EFI. To launch Apple Hardware Test (AHT) from the Mac OS X Install disc, you must hold down the “D” key during boot.
Unlike the MacBook Pro (17-inch), the MacBook Pro (17-inch Core 2 Duo) now utilizes JST wire bundle connectors that disengage by lifting up and pulling the connector out of its mating part on the logic board. To reconnect, just snap the connector back in, making sure it is seated securely. The fans, thermal sensors, and backup battery all use this connector.
Main Memory
The memory connector is a stacked memory design. The MacBook Pro (17-inch) supports up to 2GB of RAM, and the MacBook Pro (17-inch Core 2 Duo) supports up to 3GB. However, note that in the latter, while you will have a perfectly bootable system with two (2) 2GB RAM modules—
MacBook Pro (17-inch & 17-inch Core 2 Duo) Basics— General Information
and even About This Mac will report 4GB of installed memory—the system will only be able to address 3GB of that installed RAM.
See MacBook Pro (Core 2 Duo):Memory Specifications for more information.
Main Battery
Both MacBook Pro 17-inch models use battery packs built with the same lithium polymer battery technology used in our iPod product line, though the basic chemistry is no different than previous lithium ion cells. An unchanged battery controller keeps the battery calibration procedure the same as it has been since the PowerBook G4 line.
Power Adapter
All MacBook Pro models use an Apple 85-Watt Portable Power Adapter with the revolutionary MagSafe power connector. It is not compatible with any previous notebook computer.
The MagSafe connector consists of a magnet inside the computer and an attraction plate in the DC plug on the power adapter. Since the power port has a magnet built in, whenever you service the system it is recommended to put a piece of tape over the connector to avoid materials such as screws and washers from being inadvertently drawn into it.
The DC plug consists of five pins. Each pin is spring loaded.The center pin is a sense pin (2).This center pin must make contact with the computer before power is applied. Power is carried on the remaining four pins (4). The outer pins are positive terminals, the inner pair are the return paths.
Since there is no up side to the DC plug, it can go either way. To support this design, the power LED (1) is on both sides of the connector. As always, the LED will glow amber when charging the battery, and green when supplying power to the system but not charging the battery.
MacBook Pro (17-inch & 17-inch Core 2 Duo) Basics— General Information
Top Case
For both MacBook Pro 17-inch models, the sleep magnet is located on the side of the display bezel, and the sleep sensor is located to the right side of the top case just around the bottom of the perforated speaker openings.
Keyboard
Both 17-inch MacBook Pro keyboards utilize flex cables that are incompatible with previous PowerBook G4 keyboards. Also, this flex cable difference renders the 15-inch MacBook Pro keyboard incompatible with either 17-inch MacBook Pro model.
The MacBook Pro (17-inch Core 2 Duo) keyboard backlighting has been improved over the MacBook Pro (17-inch) model. In addition, the programming of the caps lock key was changed to fix a developer keyboard mapping issue, and thus cannot be used in the previous MacBook Pro
(17-inch) or the caps lock key will not be recognized.
Mass Storage (hard drive and optical drive)
The hard drive interface for all MacBook Pros is Serial ATA (SATA); thus, previous PowerBook hard drives will not work in this system.
The optical drive in both 17-inch MacBook Pro models is basically the same mechanism used in the PowerBook G4 (17-inch Double-Layer SD), but it has updated firmware.You should not interchange the two parts.
AirPort Extreme
The MacBook Pro (17-inch) uses the same AirPort Extreme card as the 15-inch MacBook Pro and does not support Bluetooth. It is the same form factor used in the iMac (Early 2006). However, there are two version of these cards. We have structured service parts to keep them separate.
The MacBook Pro (17-inch Core 2 Duo) utilizes a newer AirPort Extreme card with a three-wire antenna solution. The length of each wire and its color will help distinguish which wires go to which terminals on the card (black = longest/left, gray = medium/middle, blue = shortest/right).
The AirPort antenna for both 17-inch MacBook Pro models is located in the clutch barrel underneath the gray plastic window.
MacBook Pro (17-inch & 17-inch Core 2 Duo) Basics— General Information 10
Bluetooth
Each 17-inch MacBook Pro model has a Bluetooth module with its own separate antenna, both located in a plastic bracket to the left side of the hard drive.
However, unlike the MacBook Pro (17-inch), the Bluetooth bracket in the MacBook Pro (17-inch Core 2 Duo) comes wrapped in a foil EMI shield, which can be ordered as a separate part if it is rendered unusable for reuse during repair.
Backup Battery
The backup battery is not rechargeable. It only provides power to the real time clock and does not support system memory.
Without a power adapter connected, when you swap the finished goods battery in a running system, it must be done from sleep. The system will shutdown when you remove the battery. When you power back up, it will boot up from SafeSleep, a hibernation state.
ExpressCard
ExpressCard has replaced the PCMCIA card cage in the PowerBook G4. The ExpressCard standard supports two sizes cards, 34mm and 54mm width. MacBook Pro supports the 34mm standard.
Unlike the previous PCMCIA design, there is no eject button. The card itself is used to engage and disengaged itself from the card cage. In some designs like Ethernet ExpressCard, the card sticks out beyond the card cage. It is easy to push on the card to release it. Other cards will be flush with the MacBook Pro enclosure and will take a little more care to pop out.
Speakers
Both 17-inch MacBook Pro models sport four speakers with two separate speaker modules (left and right), each with two speakers each. Each module has expanded housing to produce greater
MacBook Pro (17-inch & 17-inch Core 2 Duo) Basics— General Information 11
sound energy than the PowerBook G4. Since the system can output a lot of sound, it is very important to make sure screws are properly tightened down. As a mobile product, a loose screw can eventually work itself free, and using the speakers at elevated volumes can also work toward loosening a screw that is not properly installed.
In addition, each speaker is driven by its own amplifier, as is the headphone port. As such, troubleshooting between speaker and left I/O board failures will require some part swapping to pinpoint the problem module (see the Sound heading in Troubleshooting section).
Infrared Board and the Apple Remote
The infrared port is placed on the front of the unit just to the left of the display latch button. This port is used in conjunction with the Apple Remote provided with each unit. It can be used to control Front Row software that manages your music, photos and videos. The remote can also be used to control other applications as well.
iSight Camera
An iSight Camera is built-in into the display bezel of both 17-inch MacBook Pro models, allowing a user to capture video and take still photos. A green LED to the right of the camera glows when the camera is on.
Unlike the standalone iSight camera, the microphone is not integrated with the camera. It is located by the left speaker.
iSight Camera Status LED
The opening for the green status LED to the right of the camera on the MacBook Pro (17-inch) no longer appears in the display bezel. When the LED lights up on the MacBook Pro (17-inch Core 2 Duo), it is now visible through a clever pattern of micro perforations.

Electrostatic Discharge (ESD)
Use a properly grounded ESD wrist strap and mat when working on the inside of the computer.
Service Manual Note
In this manual, graphics or photos are intended to help illustrate procedures or information only, and may show different levels of disassembly, board colors, configurations, 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
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 and Callout Note
All screw measurements given are the specified full length. Actual measured lengths may vary.
Screw part numbers were assigned using a pre-production unit and are subject to change.
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.
