O
bserving the Boot Routine
After you perform a visual inspection as described in the previous section, boot
the computer from a diagnostics diskette and, while the boot routine is running,
observe the computer for any indications of problems.
NOTE: To prevent possible damage to the original diagnostics diskette, always
use a backup copy of the diagnostics diskette when servicing a user's computer.
Dell recommends that users make copies of the Dell diagnostics diskette. For
instructions, see "Before You Start Testing" in Chapter 4 of the Reference and
Troubleshooting Guide.
To observe the boot routine, follow these steps:
1. Turn off the computer and any attached peripherals.
2. Insert a diagnostics diskette into the diskette drive. Turn on all periph-
erals and then the computer.
3. Watch the indicators on the top of the keyboard. After all three indica-
tors flash momentarily, the Num Lock indicator should light up and
remain on.
Do these indicators light up within approximately 10 seconds after the boot
routine starts?
Yes. Proceed to step 4.
No. Troubleshoot the power subsystem.
4. While the boot routine is running, observe the computer for any of the
following:
•
Diskette-drive and hard-disk drive access indicators — These indicators
light in response to data being transferred to or from the drives. If either
of these indicators fail to light during the boot routine, troubleshoot the
diskette-drive or hard-disk drive subsystem, as appropriate.
•
Beep codes — A beep code is a series of beeps that indicates an error
condition. If the computer emits a beep code, go to Table 3-1.
NOTE: The computer beeps once during the boot routine. This single
beep is normal and is not a beep code.
•
System error messages — These messages can indicate problems or
provide status information. If a system error message displays, go to
Table 3-2.
