Working inside your computer
Safety instructions
Use the following safety guidelines to protect your computer from potential
damage and to ensure your personal safety. Unless otherwise noted, each
procedure included in this document assumes that you have read the safety
information that shipped with your computer.
WARNING: Before working inside your computer, read the safety information that
is shipped with your computer. For more safety best practices, see the
Regulatory Compliance home page at www.dell.com/ regulatory_compliance.
WARNING: Disconnect your computer from all power sources before opening the
computer cover or panels. After you finish working inside the computer,
replace all covers, panels, and screws before connecting your computer to an
electrical outlet.
CAUTION: To avoid damaging the computer, ensure that the work surface is flat,
dry, and clean.
CAUTION: To avoid damaging the components and cards, handle them by their
edges, and avoid touching the pins and the contacts. CAUTION: You should only
perform troubleshooting and repairs as authorized or directed by the Dell
technical assistance team. Damage due to servicing that is not authorized by
Dell is not covered by your warranty. See the safety instructions that is
shipped with the product or at www.dell.com/regulatory_compliance. CAUTION:
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 static
electricity which could harm internal components. CAUTION: When you disconnect
a cable, pull it by its connector or its pull tab, not the cable itself. Some
cables have connectors with locking tabs or thumbscrews that you must
disengage before disconnecting the cable. When disconnecting cables, keep them
evenly aligned to avoid bending the connector pins. When connecting cables,
ensure that the ports and the connectors are correctly oriented and aligned.
CAUTION: Press and eject any installed card from the media-card reader.
NOTE: The color of your computer and certain components may appear differently
than shown in this document.
Before working inside your computer
About this task NOTE: The images in this document may differ from your
computer depending on the configuration you ordered.
Steps 1. Save and close all open files and exit all open applications. 2. Shut
down your computer. Click Start > Power > Shut down.
NOTE: If you are using a different operating system, see the documentation of
your operating system for shut-down instructions.

Working inside your computer
3. Disconnect your computer and all attached devices from their electrical
outlets. 4. Disconnect all attached network devices and peripherals, such as
keyboard, mouse, and monitor from your computer.
CAUTION: To disconnect a network cable, first unplug the cable from your
computer and then unplug the cable from the network device.
5. Remove any media card and optical disc from your computer, if applicable.
Safety precautions
The safety precautions chapter details the primary steps to be taken before
performing any disassembly instructions. Observe the following safety
precautions before you perform any installation or break/fix procedures
involving disassembly or reassembly: Turn off the system and all attached
peripherals. Disconnect the system and all attached peripherals from AC power.
Disconnect all network cables, telephone, and telecommunications lines from
the system. Use an ESD field service kit when working inside any desktop to
avoid electrostatic discharge (ESD) damage. After removing any system
component, carefully place the removed component on an anti-static mat. Wear
shoes with non-conductive rubber soles to reduce the chance of getting
electrocuted.
Standby power
Dell products with standby power must be unplugged before you open the case.
Systems that incorporate standby power are essentially powered while turned
off. The internal power enables the system to be remotely turned on (wake on
LAN) and suspended into a sleep mode and has other advanced power management
features. Unplugging, pressing and holding the power button for 20 seconds
should discharge residual power in the system board.
Bonding
Bonding is a method for connecting two or more grounding conductors to the
same electrical potential. This is done through the use of a field service
electrostatic discharge (ESD) kit. When connecting a bonding wire, ensure that
it is connected to bare metal and never to a painted or non-metal surface. The
wrist strap should be secure and in full contact with your skin, and ensure
that you remove all jewelry such as watches, bracelets, or rings prior to
bonding yourself and the equipment.
Electrostatic discharge–ESD protection
ESD is a major concern when you handle electronic components, especially
sensitive components such as expansion cards, processors, memory DIMMs, and
system boards. Very slight charges can damage circuits in ways that may not be
obvious, such as intermittent problems or a shortened product life span. As
the industry pushes for lower power requirements and increased density, ESD
protection is an increasing concern. Due to the increased density of
semiconductors used in recent Dell products, the sensitivity to static damage
is now higher than in previous Dell products. For this reason, some previously
approved methods of handling parts are no longer applicable. Two recognized
types of ESD damage are catastrophic and intermittent failures. Catastrophic
Catastrophic failures represent approximately 20 percent of ESD-related
failures. The damage causes
an immediate and complete loss of device functionality. An example of
catastrophic failure is a memory DIMM that has received a static shock and
immediately generates a “No POST/No Video” symptom with a beep code emitted
for missing or nonfunctional memory. Intermittent Intermittent failures
represent approximately 80 percent of ESD-related failures. The high rate of
intermittent failures means that most of the time when damage occurs, it is
not immediately recognizable. The DIMM receives a static shock, but the
tracing is merely weakened and does not immediately produce outward symptoms
related to the damage. The weakened trace may take weeks or months to melt,
and in the meantime may cause degradation of memory integrity, intermittent
memory errors, etc. The more difficult type of damage to recognize and
troubleshoot is the intermittent (also called latent or “walking wounded”)
failure. Perform the following steps to prevent ESD damage:
Working inside your computer
7
Use a wired ESD wrist strap that is properly grounded. The use of wireless
anti-static straps is no longer allowed; they do not provide adequate
protection. Touching the chassis before handling parts does not ensure
adequate ESD protection on parts with increased sensitivity to ESD damage.
Handle all static-sensitive components in a static-safe area. If possible, use
anti-static floor pads and workbench pads. When unpacking a static-sensitive
component from its shipping carton, do not remove the component from the anti-
static
packing material until you are ready to install the component. Before
unwrapping the anti-static packaging, ensure that you discharge static
electricity from your body. Before transporting a static-sensitive component,
place it in an anti-static container or packaging.
ESD field service kit
The unmonitored Field Service kit is the most commonly used service kit. Each
Field Service kit includes three main components: anti-static mat, wrist
strap, and bonding wire.
Components of an ESD field service kit
The components of an ESD field service kit are: Anti-Static Mat The anti-
static mat is dissipative and parts can be placed on it during service
procedures. When using an
anti-static mat, your wrist strap should be snug and the bonding wire should
be connected to the mat and to any bare metal on the system being worked on.
Once deployed properly, service parts can be removed from the ESD bag and
placed directly on the mat. ESD-sensitive items are safe in your hand, on the
ESD mat, in the system, or inside a bag. Wrist Strap and Bonding Wire The
wrist strap and bonding wire can be either directly connected between your
wrist and bare metal on the hardware if the ESD mat is not required, or
connected to the anti-static mat to protect hardware that is temporarily
placed on the mat. The physical connection of the wrist strap and bonding wire
between your skin, the ESD mat, and the hardware is known as bonding. Use only
Field Service kits with a wrist strap, mat, and bonding wire. Never use
wireless wrist straps. Always be aware that the internal wires of a wrist
strap are prone to damage from normal wear and tear, and must be checked
regularly with a wrist strap tester in order to avoid accidental ESD hardware
damage. It is recommended to test the wrist strap and bonding wire at least
once per week. ESD Wrist Strap Tester The wires inside of an ESD strap are
prone to damage over time. When using an unmonitored kit, it is a best
practice to regularly test the strap prior to each service call, and at a
minimum, test once per week. A wrist strap tester is the best method for doing
this test. If you do not have your own wrist strap tester, check with your
regional office to find out if they have one. To perform the test, plug the
wrist-strap’s bonding-wire into the tester while it is strapped to your wrist
and push the button to test. A green LED is lit if the test is successful; a
red LED is lit and an alarm sounds if the test fails. Insulator Elements It
is critical to keep ESD sensitive devices, such as plastic heat sink casings,
away from internal parts that are insulators and often highly charged. Working
Environment Before deploying the ESD Field Service kit, assess the situation
at the customer location. For example, deploying the kit for a server
environment is different than for a desktop or portable environment. Servers
are typically installed in a rack within a data center; desktops or portables
are typically placed on office desks or cubicles. Always look for a large open
flat work area that is free of clutter and large enough to deploy the ESD kit
with additional space to accommodate the type of system that is being
repaired. The workspace should also be free of insulators that can cause an
ESD event. On the work area, insulators such as Styrofoam and other plastics
should always be moved at least 12 inches or 30 centimeters away from
sensitive parts before physically handling any hardware components ESD
Packaging All ESD-sensitive devices must be shipped and received in static-
safe packaging. Metal, static-shielded bags are preferred. However, you should
always return the damaged part using the same ESD bag and packaging that the
new part arrived in. The ESD bag should be folded over and taped shut and all
the same foam packing material should be used in the original box that the new
part arrived in. ESD-sensitive devices should be removed from packaging only
at an ESD-protected work surface, and parts should never be placed on top of
the ESD bag because only the inside of the bag is shielded. Always place parts
in your hand, on the ESD mat, in the system, or inside an anti-static bag.
Transporting Sensitive Components When transporting ESD sensitive components
such as replacement parts or parts to be returned to Dell, it is critical to
place these parts in anti-static bags for safe transport.
ESD protection summary
It is recommended that all field service technicians use the traditional wired
ESD grounding wrist strap and protective anti-static mat at all times when
servicing Dell products. In addition, it is critical that technicians keep
sensitive parts separate from all insulator parts while performing service and
that they use anti-static bags for transporting sensitive components.
