chapter 2 T ROUBLESHOOTING Follow these basic steps when beginning the troubleshooting process: 1. 2. 3. 4. 5. Complete the preliminary steps listed in Section 2.1. Run the Power-On Self-Test (POST) as described in Section 2.3. Run Computer Setup as described in Section 2.5. Run the Computer Checkup (TEST) as described in Section 2.6.
PAGE 24
2.1 Preliminary Steps IMPORTANT: Use AC power when running POST, Computer Setup, or Computer Checkup. A low battery condition could initiate Hibernation and interrupt the test. Before running POST and Computer Checkup, complete the following steps: 1. Obtain established passwords. If you must clear the passwords, go to Section 2.2. 2. Ensure that the hard drive is installed in the computer. 3.
PAGE 25
2.2 Clearing Passwords The power-on password prevents use of the computer until the password is entered. The setup password prevents unauthorized changes to Computer Setup. To clear the passwords, you must remove all power from the system board. If you do not know the passwords, use the following procedure to clear the password: 1. 2. 3. 4. 5. 6. Remove all battery packs from the battery bay and MultiBay, if applicable. Disconnect the AC power. Remove the real-time clock battery. Wait five minutes.
PAGE 26
2.4 POST Error Messages If the system is not functioning well enough to run POST, or if the display is not functioning well enough to show POST error messages, refer to the Troubleshooting tables in Section 2.6. If POST detects an error, one of the following events occurs: A message with the prefix "WARNING" appears informing you where the error occurred. The system pauses until you press F1 to continue. ■ A message with the prefix "FATAL" appears informing you where the error occurred.
PAGE 27
If you receive one of the error messages listed in Table 2-2, follow the recommended action. Table 2-2 Warning Messages Message Description CMOS checksum invalid, run SCU CMOS RAM information has been corrupted. CMOS RAM has lost power. CMOS failure, run SCU Diskette controller error Recommended Action Run Computer Setup to reinitialize CMOS-RAM. Run Computer Setup to reinitialize CMOS-RAM.
PAGE 28
Fatal errors emit a beep and may display a FATAL message. Fatal errors indicate severe problems, such as a hardware failure. Fatal errors do not allow the system to resume. Some of the Fatal error beep codes are listed at the end of this section. Table 2-3 Fatal Error Messages Message Description Beep Code CMOS RAM test failed A walking bit test of CMOS RAM location 0E (Hex) - 3F (Hex) failed.

4.2.2 Cables and Connectors Cables must be handled with extreme care to avoid damage. Apply only the tension required to unseat or seat the cables during removal and insertion. Handle cables by the connector whenever possible. In all cases, avoid bending, twisting, or tearing cables. Ensure that cables are routed in such a way that they cannot be caught or snagged by parts being removed or replaced. Handle flex cables with extreme care; they tear easily.
PAGE 68
4.4 Preventing Electrostatic Damage Many electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure determine the degree of sensitivity. Networks built into many integrated circuits provide some protection, but in many cases the discharge contains enough power to alter device parameters or melt silicon junctions. A sudden discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or microcircuitry.
PAGE 69
4.4.2 Workstation Precautions Use the following grounding precautions at workstations: ■ ■ ■ ■ ■ ■ ■ ■ Cover the workstation with approved static-dissipative material (refer to Table 4-2 later in this chapter). Use a wrist strap connected to a properly grounded work surface and use properly grounded tools and equipment. Use field service tools, such as cutters, screwdrivers, and vacuums that are conductive.
PAGE 70
Other grounding equipment recommended for use in preventing electrostatic damage include: ■ Antistatic tape ■ Antistatic smocks, aprons, or sleeve protectors ■ Conductive bins and other assembly or soldering aids ■ Non-conductive foam ■ Conductive tabletop workstations with ground cord of one-megohm resistance ■ Static-dissipative table or floor mats with hard tie to ground ■ Field service kits ■ Static awareness labels ■ Material-handling packages ■ Non-conductive plastic bags, tubes, or
