5 Troubleshooting Procedures 5.1 Introduction This section provides an overview of the fault isolation process, provides guidelines for isolating 660 Series computer malfunctions to replaceable subassemblies and provides instructions for executing diagnostics and interpreting error messages. 5.
START COMPUTER TROUBLE INDICATION ? NO PORT REPLICATOR PROBLEMS? YES When Power button is pressed, no indication of power is present (dark LCD, no Status icons lit, no disk drive activity, etc.) DEAD COMPUTER SYMPTOMS ? Yes YES NO Press Power button; Selftest automatically runs when power turned on. NO ATTACH DESKTOP DEVICES DIRECTLY TO NOTEBOOK TO ISOLATE PORT REPLICATOR PROBLEMS See Paragraphs 5.3.1 & 5.3.2 SEE PARAGRAPH 5.4 RUN SELF TEST ERROR MESSAGE ? YES SEE PARAGRAPHS 5.3.3.1 and 5.
5.3 Troubleshooting Procedures The built-in self test program and the disk resident diagnostics program (PC-Doctor) are useful tools in computer troubleshooting. However, if the computer has a power, keyboard or display problem, you must first solve this problem before running diagnostics. If the computer powers up and displays messages on the LCD or emits a series of beeps, skip to Paragraph 5.3.3 for further instructions. 5.3.
♦ Faulty LCD - Replace the cover-display assembly as described in Section 6 of this manual. ♦ Low battery - Use a fully charged battery and/or plug in the AC adapter. Table 5-1 contains fault isolation information for Display Problems on the notebook. Symptoms are listed along the left side of the chart and the various Display FRUs are listed along the top of the chart. Within the body of the table are the probabilities of each of the FRUs causing that particular problem.
5.3.3 Fault Isolation Using Power On Self Test When the computer is first powered up, it automatically performs a Power On Self Test (POST) that checks the notebook’s central hardware and memory functions. During POST (which lasts for a few seconds), the display shows copyright and version number information. Note: Some procedures in this paragraph require you to use keystroke sequences, such as Ctrl-Alt-Del. To execute a keystroke sequence such as this, you must press all three keys simultaneously. 5.3.
Table 5-2 Power On Self Test Error Messages Message Possible Cause Action Diskette drive A failure The drive failed or is missing. Check the drive to determine the problem. Diskette read failure press F1 to retry boot, F2 for SETUP utility The disk is either not formatted or is defective. Replace the disk with a bootable disk and retry. Display adapter failed, using alternate The primary video adapter failed. Check the primary video adapter.
Table 5-2 POST Error Messages (continued) Message Possible Cause Action No boot device available press F1 to retry boot, F2 for SETUP utility Either disk drive A:, the fixed disk, or both the disk and fixed disk are defective. Try rebooting. If problem persists, replace the disk or the fixed disk. No boot sector on fixed disk - press F1 to retry boot, F2 for SETUP utility The C: drive is not formatted or is not bootable. Format the C: drive and make it bootable.
Table 5-2 POST Error Messages (continued) Message Possible Cause Action Keyboard clock line failure The keyboard, the keyboard cable connection, or the keyboard controller is defective. Make sure the keyboard cable and keyboard are connected properly. Check the keyboard controller and the system board. Turn the power off, then back on again. If the problem persists, contact qualified service personnel. Keyboard data line failure The keyboard controller firmware has failed.
Try running PC-Doctor (Paragraph 5.5) if possible to verify the source of problem.

6 Field Service 6.1 Introduction This section contains general preventive and corrective maintenance procedures that apply to all members of the Extensa 660 Notebook family. The first part of the section describes the computer cleaning procedures and preferred handling procedures for sensitive components (e.g., disk drives, batteries).
♦ Never place anything on top of the computer, particularly when it is operating or charging (could result in overheating and damage to the computer). ♦ Never move the computer while the hard drive is rotating (press the Suspend button to put the computer in a Sleep mode before closing cover). ♦ Never expose the computer hard disk drive(s) or disks to strong magnetic fields such as those generated by transformers, speakers, or telephone handsets. 6.2.
6.3 Required Tools and Equipment All Extensa Notebook corrective maintenance procedures can be performed using the following tools: ♦ Tweezers ♦ Plastic Stick ♦ Small flat-blade screwdriver ♦ Small Phillips® screwdriver ♦ 5 mm Nut Driver Caution: All boards, options and peripherals contain components that are sensitive to static electricity. When handling any of these items, protect against static electricity by using wrist grounding straps and grounded working mats.
