Working on your computer
Topics:
• Safety precautions
• Before working inside your computer
• After working inside your computer
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/x procedures involving disassembly or reassembly:
• Turn o 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 eld service kit when working inside any notebook 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.
1
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 o. 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 15 seconds should discharge residual power in the system board, notebooks
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
eld 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.
Working on your computer 7
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 dicult 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 oor 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 eld 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 eld service kit
The components of an ESD eld 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 oce to nd 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 dierent 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 oce desks or cubicles. Always look for a large open at 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
Working on your computer

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 eld 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.
