Note About Images in This Manual

Because a pre-production model was used for most of the images shown in this manual, you may notice small dierences in appearance between the image pictured and the computer you are servicing. However, although the appearance may dier, the steps and sequence are the same unless noted.
Screw sizes shown are approximate and indicate the total length including the screw head.

Battery Precautions

This computer contains an internal-only battery that is serviceable by Apple-authorized service providers only. Tamper-proof screws are employed to prevent customers from attempting to remove it.
WARNING: Every time you remove the bottom case, disconnect the battery cable from the
logic board.
WARNING: Because the battery is internal and connected to the logic board by a cable, it MUST
BE DISCONNECTED before performing service procedures. If you fail to do so, live current from
the battery will short circuit the components and render the logic board and/or LVDS cable unusable.

Serial Number Location

Serial Number On Bottom Case

Turn over the computer to see the serial number etched on the bottom case near the hinge.
2010-06-11
MacBook Pro (17-inch, Mid 2010) Basics — Serial Number Location 12
Page 13

Transferring the Serial Number

When replacing a bottom case, retain the customer’s bottom case until the repair is complete. Before installing the replacement bottom case, use a ne tip permanent marker to write the original serial number clearly and legibly in uppercase box letters directly onto the inside of the new bottom case.
CAUTION: Take great care in deciphering the small typeface of the etched serial number on the bottom case. You might need a magnifying glass to see it clearly. It is imperative that you transfer the correct alphanumeric characters. Keep in mind that Apple serial numbers always use the numbers 1 and 0 instead of the Roman letters “I” and “O.”
2010-06-11
Note: If your repair site has a bar code reader, you can also nd a set of serial numbers on the memory card carrier (A = system; B = logic board). For information on the serial number format, refer to
http://support.apple.com/kb/CP1099?viewlocale=en_US

Clamshell Service Diagnostic Read Me

Isolating video and wireless issues in portable computers can be time consuming and confusing. The Clamshell Service Diagnostic (CSD) is a new diagnostic tool that checks Apple’s latest portable computers for the presence of AirPort, Bluetooth, LCD and Ambient Light Sensor (ALS) to assist you in quickly making a failure determination.
Troubleshooting benets of using CSD include:
• Quick way (less than 1 minute) to determine if clamshell-related modules (AirPort, Bluetooth, LCD and ALS) are electrically connected without taking apart the system.
• Results of CSD can help pinpoint if any clamshell cables may need to be reseated to logic board.
• Diagnostic results can help isolate a video or wireless issue to either the clamshell or the logic board, to avoid unnecessary replacements of these components.
CSD checks for the presence of the computer’s:
• AirPort
• Bluetooth
• LCD
• ALS
CSD does not check for the presence of the computer’s:
• iSight camera
• externally connected hardware components (such as USB or FireWire devices)
CSD does not check for issues with the OS X or other software-related problems such as application or extension conicts.

Liquid Contact Indicators

Liquid contact indicators (LCI) have been added to specic locations on current Mac portables to help determine if systems have been damaged by liquid. The sensors are only visible when the bottom case and some of the modules have been removed. Normally represented by small white dots, the LCIs turn red when they have come in contact with liquid, such as an accidental spill.
For more information, refer to Knowledge Base article HT3400: “About Liquid contact indicators (LCI) on portable computers.” http://support.apple.com/kb/HT3400

Common Reset Procedures

When a reset procedure is required for troubleshooting, follow the applicable steps:
Resetting the System Management Controller (SMC)
To reset power management via the SMC chip:
1. If the computer is on, turn it o by choosing Shutdown from the Apple () menu.
2. Connect the power adapter to the computer and to a working power source.
3. Important: Use the keys on the left side of the keyboard. On the built-in keyboard, press
Shift-Control-Option along with the power button once.
Note: When the LED on the MagSafe connector is orange, resetting the SMC will change it to green for a few seconds, indicating that SMC was correctly reset.
4. Wait 5 seconds and press the power button to restart the computer. Note: If bottom case is removed, you may alternately reset the SMC by disconnecting the power adapter and the main battery, and holding the power button down for ve seconds.

Display Issue: Pixel Anomalies

When displaying a single color over the screen area, the LCD panel might show one or more pixels that are not properly lit. To determine if 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, all-red, all-green, all-blue, or all-black 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 o
3. The number of acceptable pixel anomalies for this computer is:
Bright Up to 3 Dark Up to 5 Combination Up to 7
4. If the number of subpixel anomalies exceeds the acceptable number shown above, replace the LCD panel display assembly. Numbers outside the acceptable range would be
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 specications, and no repair is necessary.
Important: Do not release the specications 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 o.
• 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 aected subpixel being turned on (bright) or turned o (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 signicantly increase the retail price for products using LCD displays. These factors apply to all manufacturers using LCD technology—not just Apple products.

Intermittent Shutdown
Unlikely cause: hard drive, optical drive
Troubleshooting Shutdown Issues
Before troubleshooting shutdown issues, always do the following:
• Run the available Apple diagnostics to check for cause of previous shutdown(s). Running ASD also helps isolate any abnormal value reading from a thermal, voltage, or current sensor or from a fan speed meter.
• Collect all available information from the user on shutdown details: periodicity, power state when issue happens, running applications, running time before shutdown.
User-related shutdowns
A computer shutdown may be caused by user operation. Shutting down the computer (by selecting the Shut Down menu, by pressing the power button for at least 4 seconds, or by programming a timed shutdown in the Energy Saver preferences) should not be considered as a failure unless the power button or the magnetic sleep sensors are found to be defective.
Suggested steps for troubleshooting:
• Reset SMC.
• Check Energy Saver preferences settings.
• Test top case button and magnetic sleep sensor operation and secure connection to logic board.
Activity-related system shutdowns
These shutdowns are linked to system settings, devices drivers, applications, or operating system freezes.
• System could not nish the standard shutdown process and had to force shutdown.
• An installed watchdog detected that an application did not respond within the specied time. (This watchdog can be enabled in Mac OS X Server Energy Saver preferences.)
Suggested steps for troubleshooting:
• Check the system logs and activity monitor utility for clues on the freezing process.
• Check for available software and rmware updates for installed device drivers, applications, or operating system.
• Start the system from a known-good and up-to-date bootable drive for issue reproduction.
Power-related system shutdowns
These shutdowns are due to power management, poor connections or defective power sources.
• External or battery power source was removed.
• Battery went empty while computer was on.
• Battery went empty while computer was asleep.
2010-06-11
MacBook Pro (17-inch, Mid 2010) Symptom Charts — Startup and Power Issues 30
Page 31
Suggested steps for troubleshooting:
• Reset SMC.
• Check that AC cable, AC adapter and battery connections are secure to logic board.
• Verify battery and power adapter sources using the Battery and Adapter test utility.
Hardware-related system shutdown
These shutdowns are due to temperature, voltage, current, fan speed or other hardware-related sensor values going out of range.
• One of the temperature sensors reached a specied temperature limit.
• One of the voltage sensors reached a specied voltage limit.
• One of the current sensors reached a specied current limit.
Suggested steps for troubleshooting:
• Check all sensors connections and values using Apple Service Diagnostics and other available Apple Service utilities.
• Conrm correct Apple-branded battery and power adapter are installed.
• Check for abnormal battery temperature.
• Check fan(s) operation.
• Conrm cleanliness of heatsink ns and air ows.
• Conrm heatsink is correctly seated on logic board and thermal material is present.
