About Apple Service Diagnostic

Apple Service Diagnostic is a diagnostic tool for detecting problems with your computer's internal hardware components such as the logic board, memory, and video RAM. It does not check externally connected hardware components such as USB devices or FireWire devices; it does not check non-Apple devices such as PCI cards from other vendors.

Before using Apple Service Diagnostic, disconnect external devices (excluding Apple keyboard, mouse, and display), and remove any non-Apple cards that were not included in the original shipping configuration of your system. It is also recommended that you disconnect any Ethernet network cables.

Apple Service Diagnostic does not check your computer for problems with the Operating System (OS) or other software related problems such as application or extension conflicts.
