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 benefits 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 conflicts.

Emerging Issues

For the latest on troubleshooting issues, refer to Global Service Exchange (GSX) and reference Service Source, Knowledge Base and the Service News tabs for product specific information.

Liquid Contact Indicators

Liquid contact indicators (LCI) have been added to specific locations on current Mac portables to help determine if systems have been damaged by liquid.The sensors are visible only 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 from an accidental spill.

For more information, refer to support 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 off 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 five 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 off
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 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.

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.
