General Information Product View
Overview The MacBook Pro is the first Mac notebook built upon the Intel Core Duo chip. From the exterior, the MacBook Pro has a similar look to the previous aluminum PowerBook notebook computers. However, as far as major part compatibility only the power cord and power adapter AC plug are the same.
MacBook Pro Basics— General Information 6
What’s New Main service and feature differences from previous models: • • • • • • • • • • • • • • • • •
Intel Core Duo microprocessor architecture: 1.83GHz, 2.0GHz, and a 2.16GHz option Higher resolution 15.4-inch display, 1440 x 960, 114 dpi (previously 1280 x 854, 101 dpi) Supports DDR2 memory up to 2GB 128MB VRAM with dual link DVI option is now standard 9.5mm slot load SuperDrive (versus the previous 12.7mm) 80GB 5400 RPM hard drive standard 100GB/120GB 5400 RPM, 100GB 7200 RPM hard drive option No modem No FireWire 800 port No PC Card slot ExpressCard/34 expansion card slot Dual display latch AirPort and Bluetooth cards and antennas are separate and in different locations The AirPort Extreme antenna assembly is in the clutch cover Infrared sensor iSight camera built in MagSafe magnetic power connector
New Parts and Procedures Main Logic Board The major change is the Intel Core Duo design with the ATI Mobility Radeon x1600 graphics chip. The FireWire 800 port and S-video connector has been removed. Composite and S-video connection is still available using the optional Apple DVI to Video adapter. Clearly, this new logic board will not fit in any previous Mac notebook or vice versa. The microprocessor is soldered to the main logic board. It is not upgradable. To accompany these hardware changes, the boot architecture is now based on Extensible Firmware Interface (EFI). EFI replaces the Open Firmware (OF). Services provide by OF such as boot snag keys such as “C” for boot from optical, “N” for network boot, and “T” for Target Disk Mode are still available under EFI. The one change is the “D” key is used to launch Apple Hardware Test from the Mac OS X Install disc.
Main battery MacBook Pro uses a new battery pack. It built with lithium polymer battery cells. This technology is used with our iPod product line and the base chemistry is the same as the previous lithium ion cells. This battery pack uses the same controller as the PowerBook G4 (15-inch Double-layer SD). As such the battery calibration procedure is the same.
MacBook Pro Basics— General Information 7
Power Adapter The system was designed to use the new Apple 85-Watt Portable Power Adapter. This power adapter comes with the new MagSafe power connector. It is not compatible with any previous notebook computer. The MagSafe connector consists of a magnet and an attraction plate. The magnet is placed within the computer. The attraction plate is part of the DC plug on the power adapter. 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. The outer pins are positive terminals, the inner pair are the return paths.
The pin pairs to either side of the sense pin are redundant. As such, the plug can be put in two ways. To support this design, the power LED (1) is on both side of the connector. The behavior of the LED is the same as before, amber for charging the battery, green for supplying power, but not to charge the battery.
MacBook Pro Basics— General Information 8
As the computer port has the magnet, as you are servicing the system it is recommended to put a piece of tape over the connector to avoid materials such as screws and washers to be inadvertently drawn into it.
15.4-inch Display The MacBook Pro is the first Mac notebook to the use the 15.4-inch size display. In addition, it is the brightness display used. As such, care must be exercised to avoid damaging the display panel. As you will see in the design, contact with the rear of the panel has been minimized. Do not put any new material such as tape on the back of the display panel nor press hard on it while handling it.
Top Case As the sleep magnet has been relocated to the side of the display bezel, the sleep sensor is now located to the right side of the top case just around the bottom of the perforated
Keyboard The keyboard is the same design as shipped with the PowerBook G4 (15-inch/17-inch Double Layer SD) except the flex cables. In particular, the keyboard backlight flex has changed. As such no other internal keyboard is compatible with MacBook Pro.
Mass Storage (Hard drive and optical drive) The hard drive has changed to a Serial ATA interface. This drive is new and previous PowerBook drives will not work in this system. The optical drive is a 9.5mm high drive. Previously optical drive has 12.7mm height. As with previous designs, the drive should be flat in its compartment before fastening it down. This step ensures proper path for optical media to enter and exit the drive.
MacBook Pro Basics— General Information 9
AirPort Extreme The AirPort Extreme card is a new card design. Unlike the most recent card, it does not support Bluetooth, It is the same form factor as used on the iMac (Spring 2006). However, there are two version of these cards. We have structured our service parts to keep the two separate. The AirPort antenna is no longer in the display housing. In the clutch barrel, there is a gray plastic insert. The AirPort antenna is underneath this plastic window.
Bluetooth Bluetooth has returned as a separate card. In addition, it has its own antenna. It is a little board which is place in front of the hard drive near where the top case meets the bottom.
Back up battery The back battery is no longer a rechargeable. It only provides power to the real time clock and does not support system memory. If you don’t have a power adapter connected, when you swap a 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 hiberation.
ExpressCard ExpressCard has replaced the PCMCIA card cage. 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 stick 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.
MacBook Pro Basics— General Information 10
IR and the Apple Remote Infrared port is placed on the front of the unit just to the right 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 has been built-in into the display bezel. It allows a user to capture video and take still photos. The green LED to the right of the camera is on when the camera is on.
Unlike the standalone iSight camera, the microphone is not integrated with the camera. It is located as previous Mac notebooks by left speaker.

Hardware Diagnostics AppleCare offers two diagnostics for MacBook Pro. Apple Hardware Test (AHT) is shipped with every machine and targeted for end-users to troubleshoot their machine. Apple Service Diagnostics (ASD) is offered to Service Providers for more in-depth troubleshooting. Both applications are available for download from Knowledge Base article 112125: Service Diagnostics Matrix.
Apple Hardware Test (AHT) 3A107 Notes: • AHT 3A107 is not backwards compatible with previous Macintosh notebook computers. • Starting with MacBook Pro, the Apple Hardware Test version numbering changed. All Apple Hardware Tests will be number sequentially starting with the prefix “3A.” This approach will provide each AHT release a unique version number and eliminate confusion between the same version across different product lines. AHT on the DVD follow these steps: 1.
Insert the DVD named “MacBook Pro Mac OS X Install Disc 1” that came with your computer.
MacBook Pro Troubleshooting — General Information 180
2. Hold down “D” and restart the computer. 3. Follow the on-screen instructions. Note: Previously, the option key was held down to boot into a boot picker. You are no longer able to see the AHT volume using boot picker.
Apple Service Diagnostic (ASD) 3S101 Notes: • ASD 3S101 is not backwards compatible with previous Macintosh notebook computers. • Starting with MacBook Pro, like AHT the Apple Service Diagnostic version numbering changed. All ASD will be number sequentially starting with the prefix “3S.” This approach will provide each ASD release a unique version number and eliminate confusion between the same version across different product lines.
Troubleshooting Aids and Tips Power Button pads on logic board With the top case removed, the power button is disconnected. Instead of having to reconnect the top case to turn on the system, there are two pads on the logic board that can be shorted across (with a tool like a flat blade screwdriver) to act as the power button. These pads are located near the edge of the logic board, just above center of the hard drive. It is marked POWER BUTTON. The pads are separated with a vertical white line.
MacBook Pro Troubleshooting — General Information 181
Resetting the Power Manager (SMC) Power management is now handled by a chip called SMC. Previously, it was handled by the Power Management Unit (SMC). To reset the SMC: 1.
If the computer is on, turn it off.
2. Disconnect the power adapter and remove the main battery. 3. Hold the power button down for five seconds, then release. 4. Install the main battery and connect the power adapter. 5. Press the power button to restart the computer.
System powered test using Caps lock LED There are situations when the system is giving indications that it is shut down (no sleep light, no hard drive access, screen is dark, no fan, and so on). However, the logic board may still be running. In this case, the logic board is drawing power and generating heat. Warning: In this situation, if the computer is put in an enclosed environment like a carrying bag, the computer can overheat. Check this situation by pressing the caps lock key. If the LED glows, the power manager is running on the logic board. After pressing the caps lock key and perhaps other methods of waking it up fails, including closing the lid to go to sleep and try waking again, hold the power button down for six seconds to force a shut down of the computer. Restart the system to check if it boots up normally. Note: Previously when the keyboard was connected directly to the power manager this method worked under all conditions, however as a USB device, the OS may be hung and the keyboard cannot respond. So if the caps lock light does not come on, the computer may be drawing power. If in doubt, hold the power button down for six seconds to force a shut down of the computer.
MacBook Pro Troubleshooting — General Information 182
Software Troubleshooting Tips and Tools Mac OS X 10.4.5 or later only Starting with the MacBook Pro, the system requires Intel compatible system file. The system software has to be Mac OS X 10.4.5 or later.
Login window and account Mac OS X requires at least one user account to be established. This is the Administrator’s account. By default, the Accounts system preference pane has the “Log in automatically [Admin’s name]” check. This automatic login setting allows the system to boot into the Finder without having a log-in prompt. However, if this box is not checked, you will need a password to get to the Finder. In addition, you will need to create a user account after you re-install system software.
Customer forgot password If the customer forgot the password for the computer: 1.
Insert the MacBook Pro Mac OS X Install Disc 1 DVD.
2. Restart the computer while holding down the C key on the keyboard. 3. When the installer appears, chose Reset Password under the Installer Utilities menu 4. Follow the on-screen instructions.
Safe Mode Safe Mode is the state Mac OS X is in after a Safe Boot. A Safe Boot is a special way to start Mac OS X when troubleshooting. Starting up into Safe Mode does three things to simplify the startup and operation of your computer: 1.
It forces a directory check of the startup (boot) volume. It is identical to using Disk Utility’s Repair Disk or the fsck –fy terminal command.
2. It loads only required kernel extensions (some of the items in /System/Library/Extensions). 3. It disables all fonts other than those in /System/Library/Fonts 4. It moves to the Trash all font caches normally stored in /Library/Caches/com.apple.ATS/(uid)/, where (uid) is a user ID number such as 501. 5. It disables all startup items and any Login Items.
To start up into Safe Mode (to Safe Boot), do this: 1.
Be sure the computer is shut down.
2. Press the power button. 3. Immediately after you hear the startup tone, press and hold the Shift key. Note: The Shift key should be held as soon as possible after the startup tone but not before. MacBook Pro Troubleshooting — General Information 183
4. Release the Shift key when you see the screen the gray Apple and progress indicator (looks like a spinning gear). During the startup, you will see “Safe Boot” on the Mac OS X startup screen. To leave Safe Mode, restart the computer normally, without holding any keys during startup.

Application compatibility With the transition to Intel Core Duo microprocessors, previous applications written for the PowerPC microprocessor have to be re-compiled to be able to work directly with this new microprocessor chip. As with other microprocessor transitions, Apple has formed bridges for users and developers to aid in the changes, Universal binary and Rosetta.
Universal Binary Universal binary is a Mac OS X application created by a developer who modifies and recompiles an application so it runs natively on either a PowerPC-based or Intel-based Mac. This application can run on older systems and the new MacBook Pro. A universal binary application can work directly with the Core Duo microprocessor. As discussed in the following section, older non-nativve PowerPC applications can still run on MacBook Pro, but requires a Mac OS X technology called Rosetta to translate for the Core Duo processor. Universal binary applications are marked with the following logo:
Rosetta Rosetta is a Mac OS X technology which allows PowerPC application to run on an Intel-based Mac. Rosetta works behind the scenes to translate an existing, native, non-Universal application (one that was designed to run natively a PowerPC-based Mac, not a Classic application – see note) so that it can run on an Intel-based Mac—all you have to do is double-click the application!
MacBook Pro Troubleshooting — General Information 184
Note: The Classic (Mac OS 9) application do not run on MacBook Pro. Recommend customers to upgrade to Mac OS X versions.

Hardware Symptoms How to Use the Symptom Charts The Symptom Charts included in this chapter will help you diagnose specific symptoms related to the product. In this release, a section is dedicated to the normal start up of the Intel-based MacBook Pro with dedicated chart to identify and troubleshoot “no power, no video” and “power, no video” symptoms. The steps to solve a symptom are listed sequentially. You might not need to perform every step before the symptom is solved. Start with the first step, and then test for the symptom. If the symptom persists, replace any modules you removed, go to the next step, and test again. Continue down the list until the symptom is solved.
Startup Startup Sequence The Intel-based MacBook Pro starts up very much like the previous professional Macintosh notebook computers. If power is available to the system, after pushing the power on button, the system will start to boot up. • The screen will stay dark. The sleep LED will glow solid. This will last a few seconds. • As the system boots, a Power-on test will be performed. See Error Codes listed below for failure results. • If the system is not muted, you will hear a boot beep. The backlight will turn on and the sleep LED will turn off. • The screen is gray in color. The Apple logo will appear and then the turning gear will appear. • The desktop pattern will show up, as well as the menu bar start populating.
No Power, No Video The computer will not power on (no fan movement, hard drive spin up and display is not lit) 1.
Remove any connected peripherals and eject any ExpressCard.
2. Check that the battery has enough charge to start the computer by pressing the button next to the LEDs on the battery. At least one LED must light solid (not flashing). 3. Connect a known-good Apple 85W Portable Power Adapter and power cord or plug to a known-good power outlet; make sure the DC plug is properly inserted. The DC plug should light up, if not, replace left I/O board. If not go to the troubleshooting, MagSafe connector. MacBook Pro Troubleshooting — Hardware Symptom Charts 186
4. Try powering up without the battery installed If it boots, replace battery connector cable. 5. Reset the power manager. See new procedures under the “Resetting the Power Manager)” heading in the Hardware Troubleshooting Tools and Tips section. Warning: Resetting the power manager will permanently remove a RAM disk, if present, and all of its contents. You will also need to reset the date and time (using the Date & Time system preference pane). 6. Boot up the system and check the sleep indicator. If it turns on solid and turns off, the main logic board is getting power and completing the boot cycle. If no video appears, there is an issue turning the video turn-on or system software is corrupted. Try booting off the Mac OS X Install DVD. If the light does not turn off, the boot cycle is not being complete. This may be cause by the hard drive not being seen by the system, system software corrupted or possibly a hardware issue. 7.
Press Caps Lock key to see if key light comes on. If it does, hold power button down for six seconds to shut down the computer and restart.
8. If it still doesn’t start, verify power button cable is connected properly to top case flex cable assembly and that the flex cable is connected correctly to the logic board, if power button is not functioning correctly or damaged, replace the top case. 9. Disconnect keyboard completely. Inspect connectors. Restart with keyboard disconnected. 10. Remove any additional RAM. 11. Try removing the AirPort Extreme card from its socket and start the computer. If it starts, shut it down and check the flex cable connector and the connector on the logic board and replace the damaged parts. 12. Reseat these flex cables: • Left I/O flex cable • Hard drive flex cable (will boot to flashing folder) • Optical drive flex cable • Trackpad flex cable 13. If the computer starts up, inspect the flex cable connector and its connector on the logic board for damage and replace the damaged parts. 14. Try known-good Left I/O board. 15. Replace logic board.
MacBook Pro Troubleshooting — Hardware Symptom Charts 187
Error Codes The computer automatically performs a power-on self test when it is turned on after being fully shut down (not a restart). This section describes what to do if beeps are heard during the startup. When this occurs, the sleep LED will stay on—occasionally flashes. MacBook Pro relies on a combination of tones and blinking sleep LED to display Power On Self Test (POST) error codes. If the computer detects no SDRAM (Synchronous Dynamic Random Access Memory, also referred to as RAM) or the RAM installed does not meet the appropriate specifications, the screen will remain black but the power LED on the front of the computer will blink once per second to signal the error. This error condition may be due to physically damaged RAM, installing the incorrect type of RAM, or not having RAM installed. Some RAM may appear to pass the Power-On-Self-Test (POST) but still cannot be used by the operating system. In this case, the computer will display a gray screen, sound three tones and blink the power LED on the front of the computer three times, pause, and repeat the blinking until the computer is turned off. Related Knowledge Base articles: 303083: Intel-based Mac Power On Self Test RAM error codes
Blue screen appears (a spinning disc cursor may also be visible), Prohibitory Sign appears, Restart dialog box appears (Mac OS X 10.2 kernel panic window), or Gray screen during startup

Short battery life Three categories to consider: • There is a system issue (not the battery). -- f you have the customer’s power adapter, plug it into a known good outlet and verify that it can charge the system. Also make sure it is the correct 85W adapter. -- Plug a known good 85W adapter into a known good outlet. Verify that the DC connector is fully seated into the computer. -- Check whether the customer’s system is setup for heavy battery power use (AirPort on, optical media always in drive, Energy Savings set to Highest Performance, etc.) -- Test the computer with all third-party devices (printers, hubs, third-party keyboard or mouse) removed. -- Reset the power manager. See new procedures under the “Resetting the Power Manager Unit (SMC)” heading in the Hardware Troubleshooting Tools and Tips section. • The battery needs calibration, or it is nearing the end of its useful life. -- Calibration should be done when you first use the battery, and every few months after. It allows the battery to properly calculate how much power is left in the battery. -- The battery is a consumable part. It can be charged and discharged only so many cycles before it becomes depleted and can no longer hold a charge. -- Note: The battery calibration procedure as follows: 1.
Plug in the power adapter and fully charge your battery until the light on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
2. Allow the battery to rest in the fully charged state for two hours or longer. You may use your computer during this time as long as the adapter is plugged in.
MacBook Pro Troubleshooting — Hardware Symptom Charts 194
3. Disconnect the power adapter with the computer on and start running it from the battery. You may use your computer during this time. When your battery gets low, you will see the low battery warning dialog on the screen. 4. Continue to keep your computer turned on until it goes to sleep. Save all your work and close all applications when the battery gets low and before the system goes to sleep. 5. Turn off the computer or allow it to sleep for five hours or longer.
•
6. Connect the power adapter and leave it connected until the battery is fully charged again. The battery has a defect. -- Symptoms include, but are not limited to, a relative new battery that will not charge at all, reports an “X” in the menu bar icon, status light on its case that will not go out. In the first two cases, the battery may need calibration—try this first. In addition, after troubleshooting at the system level, if it is demonstrated that the battery is causing abrupt shut-downs or goes to sleep without warning, the battery can be considered severely degraded and follow the criteria below. -- Warranty Note: If the battery was purchased (either with the computer or as a standalone part) in the last 90 days and exhibits severely degraded performance (as defined above) provide an in-warranty replacement. If the battery was purchased between the last 90 to 365 days, have the customer calibrate their battery. If after recalibration, the battery still exhibits severely degraded performance, then provide an in-warranty replacement. If the battery was purchased more than 365 days ago, the customer will need to purchase a new battery.

When displaying a single color over the screen area, the LCD panel shows one or more pixels that are not properly lit To determine whether or not the display has an acceptable number of pixel anomalies, follow the steps below: 1.
Set the display image to one of the following colors: all-white display, all-red display, all-green display, or all-blue display. Knowledge Base article 112125: Service Diagnostics Matrix, has the LCD Tester Diagnostic Utility that will generate these patterns on the screen.
2. Using a jeweler’s loupe, pocket microscope, or other magnifying device, identify and count each pixel anomaly: • Bright subpixel anomaly = subpixel that is always on • Dark subpixel anomaly = subpixel that is always off 3. The number of acceptable pixel anomalies for this system is: Acceptable Number of Subpixel Anomalies Bright
Up to 3
Dark
Up to 5
Combination
Up to 7
4. If the number of subpixel anomalies exceeds the acceptable number listed in the above chart, replace the display panel assembly. MacBook Pro Troubleshooting — Hardware Symptom Charts 196
Replace Bright
4 or more
Dark
6 or more
Combination
8 or more
5. If the number of subpixel anomalies is acceptable, explain to the customer that the pixel anomalies are within specifications, and no repair is necessary. Important: Do not release the specifications to customers. Instead, inform them that a certain number of subpixel anomalies are considered acceptable, and these factors apply to all manufacturers using LCD technology—not just Apple products. When speaking with customers, please use the following explanation: Active-matrix LCD technology uses rows and columns of addressable locations (pixels) that render text and images on screen. Each pixel location has three separate subpixels (red, green, and blue) that allow the image to be rendered in full color. Each subpixel has a corresponding transistor responsible for turning the subpixel on or off. There are typically millions of these subpixels on an LCD display. For example, the LCD panel used in the Apple Cinema HD display is made up of 2.3 million pixels and 6.9 million red, green, and blue subpixels. Occasionally, a transistor does not work perfectly, which may result in the affected subpixel being turned on (bright) or turned off (dark). With the millions of subpixels on a display, it is quite possible to have a low number of faulty transistors on an LCD. Therefore, a certain number of subpixel anomalies are considered acceptable. Rejecting all but perfect LCD panels would significantly increase the retail price for products using LCD displays. These factors apply to all manufacturers using LCD technology—not just Apple products.

Difficulty writing to optical media 1.
Verify the correct type of disc is being used.
2. Try a different brand or speed of CD-R disc. Note: Some brands of 24x or 32x CD-R media may not work with the SuperDrive. Note: There are two factors in the ability for the optical drive to write to media. - First, there are varying qualities of blank optical media. Some media are made to such low specifications that the ability for the drive to write to it is marginal. There are variations in optical media even under the same brand. Some brands source their optical media from a variety of manufacturers, so there may be variations in the quality. - Second, an optical drive that supports writing to a CD-R/RW or DVD-R/RW disc requires a special writing algorithm for discs from different disc manufacturers. There are hundreds of disc manufacturers, it is impossible to implement writing algorithms for each disc manufacturer. Usually, drive manufacturers implement special writing algorithms for discs from major disc manufacturers. For discs that are not supported by the drive with special writing algorithms, the drive will use a generic writing algorithm to write the disc. In this case, the writability and readability may not be optimal. 3. Replace optical drive flex cable. 4. Replace optical drive.
