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.

NOTE: Before working inside your computer, read the safety information that shipped with your computer. For more

safety best practices, see the Regulatory Compliance home page at www.dell.com/regulatory_compliance.

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 electrical outlet.

CAUTION: To avoid damaging the computer, ensure that the work surface is flat and clean.

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: 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 shipped with the product or at www.dell.com/regulatory_compliance.

CAUTION: Before touching anything inside your computer, ground yourself by using a wrist grounding strap or by

periodically 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 on its connector or on its pull tab, not on the cable itself. Some cables have

connectors with locking tabs or thumb-screws that you must disengage before disconnecting the cable. When

disconnecting cables, keep them evenly aligned to avoid bending any connector pins. When connecting cables, ensure

that the ports and 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

NOTE: The images in this document may differ from your computer depending on the configuration you ordered.

Before you begin

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.

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.

5. Remove any media card and optical disc from your computer, if applicable.

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 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

6Working inside your computer

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

CAUTION: Leaving stray or loose screws inside your computer may severely damage your computer.

1. Replace all screws and ensure that no stray screws remain inside your computer.

2. Connect any external devices, peripherals, or cables you removed before working on your computer.

3. Replace any media cards, discs, or any other parts that you removed before working on your computer.

4. Connect your computer and all attached devices to their electrical outlets.

5. Turn on your computer.
