Before Working Inside Your Computer
Use the following safety guidelines to help protect your computer from potential damage and to help ensure your own
personal safety.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the
Product Information Guide.
CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card.
Hold a card by its edges or by its metal mounting bracket. Hold a component such as a processor by its
edges, not by its pins.
NOTICE: Only a certified service technician should perform repairs on your computer. Damage due to servicing that is
not authorized by Dell is not covered by your warranty.
NOTICE: When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some
cables have a connector with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs
before you disconnect the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any
connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and aligned.
NOTICE: To avoid damaging the computer, perform the following steps before you begin working inside the computer.
1. Turn off your computer.
NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the
network port or device.
2. Disconnect any telephone or telecommunication lines from the computer.
3. Disconnect your computer and all attached devices from their electrical outlets, and then press the power button to
ground the system board.
NOTICE: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface,
such as the metal at the back of the computer. While you work, periodically touch an unpainted metal surface to
dissipate any static electricity that could harm internal components.

Advanced Troubleshooting: Dell Dimension 9150 Service Manual
To help you troubleshoot a problem, your computer has four lights labeled "1," "2," "3," and "4" on the front panel (see
"Front View of the Computer"). When the computer starts normally, the lights flash. After the computer starts, all four lights
display solid green. If the computer malfunctions, the color and sequence of the lights identify the problem.
Light Pattern Problem Description
Suggested Resolution
The computer is in a
normal "off" condition
or a possible pre-BIOS
failure has occurred.
Plug the computer into a working electrical outlet. Also see "Power Lights."
The diagnostic lights
are not lit after the
system successfully
boots to the operating
system.
A possible processor
failure has occurred.
Reinstall the processor and restart the computer.
Memory modules are
detected, but a
memory failure has
occurred.
If you have two or more memory modules installed, remove the modules,
reinstall one module (see "Memory"), and then restart the computer. If
the computer starts normally, reinstall an additional module. Continue
until you have identified a faulty module or reinstalled all modules
without error.
If available, install properly working memory of the same type into your
computer (see "Memory").
If the problem persists, contact Dell.
A possible graphics
card failure has
occurred.
If the computer has a graphics card, remove the card (see "Cards"),
reinstall it, and then restart the computer.
If the problem still exists, install a graphics card that you know works
and restart the computer.
If the problem persists, contact Dell.
A possible floppy drive
or hard drive failure
has occurred.
Reseat all power and data cables and restart the computer.
A possible USB failure
has occurred.
Reinstall all USB devices, check cable connections, and then restart the
computer.
No memory modules
are detected.
If you have two or more memory modules installed, remove the modules,
reinstall one module (see "Memory"), and then restart the computer. If
the computer starts normally, reinstall an additional module. Continue
until you have identified a faulty module or reinstalled all modules
without error.
If available, install properly working memory of the same type into your
computer (see "Memory").
If the problem persists, contact Dell.
Memory modules are
detected, but a
memory configuration
or compatibility error
exists.
Ensure that no special memory module/memory connector placement
requirements exist (see "Memory").
Verify that the memory modules that you are installing are compatible
with your computer (see "Memory").
If the problem persists, contact Dell.
A possible expansion
card failure has
occurred.
1. Determine if a conflict exists by removing a card (not a graphics card)
and restarting the computer (see "Cards").
2. If the problem persists, reinstall the card that you removed, remove a
different card, and then restart the computer.
3. Repeat this process for each card. If the computer starts normally,
troubleshoot the last card removed from the computer for resource
conflicts (see "Cards").
4. If the problem persists, contact Dell.
file:///T|/htdocs/systems/dim9150/en/sm/adtshoot.htm[10/31/2012 7:59:03 AM]
Advanced Troubleshooting: Dell Dimension 9150 Service Manual
Another failure has
occurred.
The computer is in a
normal operating
condition after POST.
Ensure that the cables are properly connected to the system board from
the hard drive, CD drive, and DVD drive (see "System Board
Components").
If there is an error message on your screen identifying a problem with a
device (such as the floppy drive or hard drive), check the device to make
sure it is functioning properly.
The operating system is attempting to boot from a device (such as the
floppy drive or hard drive); check system setup to make sure the boot
sequence is correct for the devices installed on your computer.
If the problem persists, contact Dell.
None.
Beep Codes
Your computer might emit a series of beeps during start-up if the monitor cannot display errors or problems. This series of
beeps, called a beep code, identifies a problem. One possible beep code (code 1-3-1) consists of one beep, a burst of three
beeps, and then one beep. This beep code tells you that the computer encountered a memory problem.
Reseating the memory modules may fix the beep code errors in the following table. If the problem persists, see "Contacting
Dell" in your Owner's Manual for instructions on obtaining technical assistance.

Drives
Your computer supports:
Two hard drives (Serial ATA)
One floppy drive
One flexbay drive
Two CD or DVD drives
Connecting Drive Cables
When you install a drive, you connect two cables—a DC power cable and a data cable—to the back of the drive and to the
system board. Some CD/DVD drives may also have an audio connector; one end of the audio cable will attach to the drive
file:///T|/htdocs/systems/dim9150/en/sm/parts.htm[10/31/2012 7:59:36 AM]
Removing and Installing Parts: Dell Dimension 9150 Service Manual
connector and the other will attach to the system board.
Connect hard drives to data connectors labeled "SATA" and connect CD/DVD drives to connectors labeled "IDE".
When you connect two IDE devices to a single IDE interface cable and configure them for the cable select setting, the device
attached to the last connector on the interface cable is primary or the boot device (drive 0), and the device attached to the
middle connector on the interface cable is the secondary device (drive 1). See the drive documentation in your upgrade kit for
information on configuring devices for the cable select setting.
Drive Interface Connectors
Most interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or
a filled-in hole on the other connector. Keyed connectors ensure that the pin-1 wire in the cable (indicated by the colored
stripe along one edge of the IDE cable—serial ATA cables do not use a colored stripe) goes to the pin-1 end of the connector.
The pin-1 end of a connector on a board or a card is usually indicated by a silk-screened "1" printed directly on the board or
card.
NOTICE: When you connect an IDE interface cable, do not place the colored stripe away from pin 1 of the connector.
Reversing the cable prevents the drive from operating and could damage the controller, the drive, or both.
When connecting an IDE cable, ensure that you align the colored stripe with the pin 1 connector. When disconnecting an IDE
cable, grasp the colored pull tab and pull until the connector detaches.
When connecting and disconnecting a serial ATA cable, hold the cable by the connector at each end. Like IDE connectors, the
serial ATA interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a
tab or a filled-in hole on the other connector.
