Observing the Boot Routine

CAUTION: The power supplies in this system produce high voltages and energy hazards, which can cause bodily harm. Only trained service
technicians are authorized to remove the system cover and access any of the components inside the system. See the System Information Guide
for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.
After you have performed an external visual inspection, boot the system and, while the boot routine is running, observe the system for any indications of
problems.
NOTE: Most of the steps in this procedure require observation of system functions and indications, some of which can occur simultaneously. It may be
necessary to reboot the system several times to complete all of these steps.
NOTE: You can run the system diagnostics from a set of diskettes you create by downloading the system diagnostics from the Dell Support website at
support.dell.com.
To observe problem indications during the boot routine, perform the following steps:
1. If the system is off, turn on all peripherals and the system.
2. Check the power-supply indicators.
Is the red fault indicator lit?
Yes. Troubleshoot the system power supply (see your Installation and Troubleshooting Guide).
No. Proceed to step 3.
3. Watch the <Num Lock>, <Caps Lock>, and <Scroll Lock> indicators on the upper-right corner of the keyboard. After all three indicators flash
momentarily, and following a long pause (approximately 30 seconds), the <Num Lock> indicator should light up and remain on (unless the Num Lock
option is set to off in the System Setup Program).
Do these indicators flash on and off within approximately 10 seconds after the boot routine starts?
Yes. Proceed to step 4.
No. Replace the keyboard with a known working keyboard. If the problem persist, troubleshoot the system power supply. If the troubleshooting
procedure indicates that the system power supply is operational, troubleshoot the memory and look for displayed codes on the 5 LEDs on the system
board (see "System Board LED
4. During the boot routine, observe the system for any of the following indications:
Beep codes — A beep code is a series of beeps that indicates an error condition. See
l
System error messages — These messages can indicate problems or provide status information. If a system error message appears, see
l
Messages."
System board LED codes — These indicators display a series of 5 lit or flashing LEDs, and can only be observed when the system cover is removed
l
(see "System Board LED
Diskette-drive and hard drive access indicators — These indicators light up in response to data being transferred to or from the drives. If either if
l
these indicators fails to light up during the boot routine, troubleshoot the diskette drive or hard drive subsystem, as appropriate.
5. Insert a copy of the diagnostics diskette into the diskette drive, and reboot the system.
Does the Diagnostics menu appear?
Yes. See "Running the System
No. Proceed to "Internal Visual

Internal Visual Inspection

NOTICE: Before you proceed with the internal visual inspection described in this section, ensure that the user has saved all open files and exited all
open application programs, if possible.
A simple visual inspection of a system's interior hardware can often lead to the source of a problem, such as a loose expansion card, cable connector, or
mounting screw. When you perform the visual inspection, see
