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