Working on your computer
Safety instructions
Prerequisites
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 the following conditions exist:
• You have read the safety information that shipped with your computer.
• A component can be replaced or, if purchased separately, installed by performing the removal procedure in reverse order.
About this task
NOTE: Disconnect 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 to the power source.
WARNING: Before working inside your computer, read the safety information that shipped with your computer. For
additional safety best practices information, see the Regulatory Compliance Homepage
CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and
simple repairs as authorized in your product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow
the safety instructions that came with the product.
CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching
an unpainted metal surface at the same time as touching a connector on the back of the computer.
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.
CAUTION: When you disconnect a cable, pull on its connector or on its pull-tab, not on the cable itself. Some cables
have connectors 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.
NOTE: The color of your computer and certain components may appear differently than shown in this document.

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:
• 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 on your computer 7
•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.
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.
Lifting equipment
Adhere to the following guidelines when lifting heavy weight equipment:
CAUTION: Do not lift greater than 50 pounds. Always obtain additional resources or use a mechanical lifting device.
1. Get a firm balanced footing. Keep your feet apart for a stable base, and point your toes out.
2. Tighten stomach muscles. Abdominal muscles support your spine when you lift, offsetting the force of the load.
3. Lift with your legs, not your back.
4. Keep the load close. The closer it is to your spine, the less force it exerts on your back.
5. Keep your back upright, whether lifting or setting down the load. Do not add the weight of your body to the load. Avoid twisting your
body and back.
6. Follow the same techniques in reverse to set the load down.
After working inside your computer
About this task
After you complete any replacement procedure, ensure that you connect any external devices, cards, and cables before turning on your
computer.
Steps
1. Connect any telephone or network cables to your computer.
CAUTION: To connect a network cable, first plug the cable into the network device and then plug it into the
computer.
2. Connect your computer and all attached devices to their electrical outlets.
3. Turn on your computer.
4. If required, verify that the computer works correctly by running ePSA diagnostics.
