                                    Troubleshooting Procedures  5-1

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.

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.
