5.1 Introduction

This section provides an overview of the fault isolation process, provides guidelines for
isolating 60x/65x Series computer malfunctions to replaceable subassemblies and
provides instructions for executing diagnostics and interpreting error messages.

5.2 Overview of Fault Isolation Process

The fault isolation process (summarized in Figure 5-1) consists of the following steps:
♦Notebook power system (including battery packs and AC adapter
connections) - refer to Paragraph 5.4.
♦Switch settings (ensure Power is On)
♦Press the Shift key to ensure that Notebook is not in Suspend mode
♦Verify if computer is configured to boot from the A: Drive or C: Drive.
♦Check LCD brightness adjustment (press Fn-Up Arrow keys to increase
brightness)
♦Ensure that computer is not set for external monitor (press Fn-F12 to select
internal screen)
♦Record and attempt to resolve any displayed error messages or error beeps
(refer to Paragraph 5.2.3.1 and Tables 5-1 and 5-2)
♦Try rebooting the system (Ctrl-Alt-Del)
♦If the computer is capable of running the Setup program; check the serial
and parallel port configurations, Sound System enable/disable, and other
features that may affect system operation.
♦Run PC-Doctor Diagnostics to further isolate problem area (refer to
Paragraph 5.4). For indicated hardware failures, cycle power and repeat self
test to verify that a hard failure has occurred.
♦Remove and replace suspect hardware (as described in Section 6 of this
manual) and retest the system using the diagnostic tests as described in
Paragraph 5.4.5.
