Notes: 1. T ypes 2179 and 6643 computers default to come up quiet (No Beep and no memory count and checkpoint code display) when no errors are detected. 2. Use Beep codes and the IBM Enhanced Diagnostics to diagnose and fix problems. 3. Check all power supply voltages before you replace the system board.
2. W ait 10 seconds. 3. Insert the IBM PC Enhanced Diagnostics Diskette into diskette drive A. 4. Power-on the system. The initial diagnostics menu will be displayed. Navigating through the diagnostics programs Use either the mouse or the keyboard to navigate through the Enhanced Diagnostics program.
2. Highlight either the Memory T est-Full or Memory T est-Quick option and press Enter . 3. v Memory T est-Full The full memory test will take about 80 seconds per MB of memory and will detect marginal, intermittent, and solid (stuck) memory failures.
– Diagnostics were run on the specified date. – Diagnostics were run on the specified IBM computer . – The diagnostic error code is recor ded correctly . v T ext: Description of the error . Note: See “IBM Enhanced Diagnostic error codes” on page 37 for error code listings.
v Performs all the steps in Quick Erase. v Provides a DOS utility that writes random data to all sectors of the hard drive. v Provide an estimate of time to completion along with a visual repr esentation of completion status. v Provides messages that warn the user about non-recoverable process.
Message Failure Found Recommended Actions 2xx-1y (For SIMMs) A memory error was detected in SIMM socket Y Replace the SIMM in the socket identified by the last digit of the error code. Re-run the T est If the same error code occurs again, replace the system board.
When to use the Low-Level Format program Notes 1. The low-level format is not available on all diagnostic diskettes. 2. Before formatting the hard disk drive, make a backup copy of the files on the drive to be formatted.

Safety information This section contains the safety information with which you need to be familiar , before you service an IBM mobile computer . General safety Follow these rules to ensure general safety: v Observe good housekeeping in the area of the machines during and after maintenance.
Observe the following rules when working on electrical equipment. v Find the room emergency power-of f (EPO) switch, disconnecting switch, or electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly .
Handling electrostatic discharge-sensitive devices Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a differ ence in charge between objects.
3. Check the power cord for the following: a. A third-wir e ground connector in good condition. Use a meter to measure third-wir e ground continuity for 0.1 ohm or less between the external ground pin and frame ground. b. The power cord should be the appropriate type as specified in the parts listings.
Problem determination tips Because there is a large variety of hardwar e and software combinations that can be encountered, use the following information to assist you in problem determination. v V erify any recent hardwar e changes. See “Hardwar e considerations” on page 108.
v Standalone diagnostics might function properly because the device that was found is the only device running. Software configuration conflicts occur when the following are true. v Hardwar e has a differ ent configuration than the software that is using it expects.
