Clamshell Service Diagnostic (CSD)
Clamshell Service Diagnostic (CSD) is a 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 clamshell or logic
board, to avoid unnecessary replacements of these components.
In the MacBook Pro (13-inch), CSD checks for the presence of the computer’s:
• AirPort
• Bluetooth
• LCD
• Ambient Light Sensor (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.
