	This guide documents fault diagnosis for the '''[[IBM 5100]] Portable Computer'''. The 5100 predates the IBM PC POST numeric error code system by six years and does not use POST beep codes; instead it relies on a '''Diagnostic ROS''' accessible via a keyboard sequence at power-on, a '''front-panel "Display Registers / RAM Hex" switch''' for live RAM inspection, and the per-symptom troubleshooting decision tree in IBM '''Maintenance Analysis Procedures (MAP)''' document '''1608314'''.
