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 whether 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 (LCIs) have been added to specic locations on current Mac portables
and desktop keyboards to help determine if systems have been exposed to liquid. Damage due
to liquid exposure is not covered by the Apple one (1) year limited warranty or the AppleCare
Protection Plan (APP). Normally represented by small white dots, the LCIs turn red when they
have come in contact with liquid, such as an accidental spill.

Important: The Liquid Contact Indicator (LCI) is a tool that helps technicians identify whether
or not a product has been in contact with liquid. Technicians should not rely solely on this tool,
but should perform a thorough examination for signs of liquid contact, such as corrosion.

For more information, refer to Knowledge Base article HT3400: “About liquid contact indicators
(LCI) on portable and desktop computers.” http://support.apple.com/kb/HT3400

Note: You need to login to GSX to be able to view this Service Provider-only Knowledge Base
article.

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.

Display Hinge Behavior

The MacBook Pro models have a unique counterbalanced clutch system that provides a
smooth, uid feel when opening, closing, or positioning the display. The counterbalanced clutch
system was designed so that when the display is vertical with respect to the ground, it will
remain in place regardless of the angle of the base.

Moving the display past vertical allows the hinges to release and the display to close. This is
normal behavior and no repair is necessary.

Refer to http://support.apple.com/kb/HT3304 for more information and to watch a video of
this hinge behavior.

Intermittent Shutdown

Unlikely cause: hard drive, optical drive

Troubleshooting Shutdown Causes

Your computer’s system log may record why it shut down or went into sleep mode. Reviewing
SMC codes in the system.log of the Console application may provide some information about
why the event occurred.

To review SMC codes in the system.log in Console:

1. Open the Console application. Console is located in the /Applications/Utilities/ folder.

2. Select Open System Log under the File menu.

3. Using the lter in the upper right corner, search for “Cause.”

4. Use the table below to interpret the cause and review the suggestion if shutdown was

unexpected.

Example: Entry found “Jun 6 18:06:28 localhost kernel[0]: Previous Shutdown Cause: 5”

By looking for the code 5 in table below, you will discover that computer shut down was
caused by user selection of System Menu option “Shutdown…”

Depending on the cause reported, the shutdown could be xed by using the Quick Check
table, or the Deep Dive troubleshooting.
