Be sure to include the CompTIA code, the troubleshooting steps you performed, and the results in the Service Instructions section of GCRM and/or GSX.

If the symptoms point to a component on the logic board, use the block diagram at the end of this chapter to help determine whether you need to replace the entire logic board.
