Working on 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 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.

WARNING: Disconnect all power sources before opening the computer cover or panels. After you nish 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 at www.Dell.com/regulatory_compliance

CAUTION: Many repairs may only be done by a certied 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 dierently than shown in this document.

Before working inside your computer

To avoid damaging your computer, perform the following steps before you begin working inside the computer.

1 Ensure that you follow the Safety instructions.

2 Ensure that your work surface is at and clean to prevent the computer cover from being scratched.

3 Turn o 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 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 nonconductive 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 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.

After unplugging the system and before removing components, wait approximately 30 to 45 seconds to allow the charge to drain from the

circuits. Remove the battery from portable desktops.

Working on your computer 9

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 nonmetal 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 dicult 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 in 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, be sure 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

10 Working on your computer

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 oce 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 dierent 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 oce 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

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.

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 rm 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, osetting 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.

USB features

The Universal Serial Bus, or well known as USB was introduced to the PC world in 1996 which dramatically simplied the connection

between host computer and peripheral devices such as mice and keyboards, external hard drive or optical devices, Bluetooth and many

more peripheral devices in the market.

Let's take a quick look on the USB evolution referencing to the table below.

Table 4. USB evolution

Type Data Transfer Rate Category Introduction Year

USB 3.0 5 Gbps Super Speed 2010

USB 2.0 480 Mbps High Speed 2000

USB 1.1 12 Mbps Full Speed 1998

USB 1.0 1.5 Mbps Low Speed 1996

USB 3.0 (SuperSpeed USB)

For years, the USB 2.0 has been rmly entrenched as the de facto interface standard in the PC world with about 6 billion devices sold, and

yet the need for more speed grows by ever faster computing hardware and ever greater bandwidth demands. The USB 3.0 nally has the

answer to the consumers' demands with a theoretically 10 times faster than its predecessor. In a nutshell, USB 3.0 features are as follows:

• Higher transfer rates (up to 5 Gbps)

• Increased maximum bus power and increased device current draw to better accommodate power-hungry devices

• New power management features

• Full-duplex data transfers and support for new transfer types

• Backward USB 2.0 compatibility

• New connectors and cable

The topics below cover some of the most commonly asked questions regarding USB 3.0.

Speed

Currently, there are 3 speed modes dened by the latest USB 3.0 specication. They are Super-Speed, Hi-Speed and Full-Speed. The new

SuperSpeed mode has a transfer rate of 4.8Gbps. While the specication retains Hi-Speed, and Full-Speed USB mode, commonly known

as USB 2.0 and 1.1 respectively, the slower modes still operate at 480Mbps and 12Mbps respectively and are kept to maintain backward

compatibility.

USB 3.0 achieves the much higher performance by the technical changes below:

• An additional physical bus that is added in parallel with the existing USB 2.0 bus (refer to the picture below).

• USB 2.0 previously had four wires (power, ground, and a pair for dierential data); USB 3.0 adds four more for two pairs of dierential

signals (receive and transmit) for a combined total of eight connections in the connectors and cabling.

78 Technology and components

• USB 3.0 utilizes the bidirectional data interface, rather than USB 2.0's half-duplex arrangement. This gives a 10-fold increase in

theoretical bandwidth.

With today's ever increasing demands placed on data transfers with high-denition video content, terabyte storage devices, high megapixel

count digital cameras etc., USB 2.0 may not be fast enough. Furthermore, no USB 2.0 connection could ever come close to the 480Mbps

theoretical maximum throughput, making data transfer at around 320Mbps (40MB/s) — the actual real-world maximum. Similarly, USB 3.0

connections will never achieve 4.8Gbps. We will likely see a real-world maximum rate of 400MB/s with overheads. At this speed, USB 3.0 is

a 10x improvement over USB 2.0.

Applications

USB 3.0 opens up the laneways and provides more headroom for devices to deliver a better overall experience. Where USB video was

barely tolerable previously (both from a maximum resolution, latency, and video compression perspective), it's easy to imagine that with

5-10 times the bandwidth available, USB video solutions should work that much better. Single-link DVI requires almost 2Gbps throughput.

Where 480Mbps was limiting, 5Gbps is more than promising. With its promised 4.8Gbps speed, the standard will nd its way into some

products that previously weren't USB territory, like external RAID storage systems.

Listed below are some of the available SuperSpeed USB 3.0 products:

• External Desktop USB 3.0 Hard Drives

• Portable USB 3.0 Hard Drives

• USB 3.0 Drive Docks & Adapters

• USB 3.0 Flash Drives & Readers

• USB 3.0 Solid-state Drives

• USB 3.0 RAIDs

• Optical Media Drives

• Multimedia Devices

• Networking

• USB 3.0 Adapter Cards & Hubs

Compatibility

The good news is that USB 3.0 has been carefully planned from the start to peacefully co-exist with USB 2.0. First of all, while USB 3.0

species new physical connections and thus new cables to take advantage of the higher speed capability of the new protocol, the

connector itself remains the same rectangular shape with the four USB 2.0 contacts in the exact same location as before. Five new

connections to carry receive and transmitted data independently are present on USB 3.0 cables and only come into contact when

connected to a proper SuperSpeed USB connection.

Technology and components 79

Windows 8/10 will be bringing native support for USB 3.0 controllers. This is in contrast to previous versions of Windows, which continue to

require separate drivers for USB 3.0 controllers.

Microsoft announced that Windows 7 would have USB 3.0 support, perhaps not on its immediate release, but in a subsequent Service Pack

or update. It is not out of the question to think that following a successful release of USB 3.0 support in Windows 7, SuperSpeed support

would trickle down to Vista. Microsoft has conrmed this by stating that most of their partners share the opinion that Vista should also

support USB 3.0.

Super-Speed support for Windows XP is unknown at this point. Given that XP is a seven-year-old operating system, the likelihood of this

happening is remote.

DDR4

DDR4 (double data rate fourth generation) memory is a higher-speed successor to the DDR2 and DDR3 technologies and allows up to 512

GB in capacity, compared to the DDR3's maximum capacity of 128 GB per DIMM. DDR4 synchronous dynamic random-access memory is

keyed dierently from both SDRAM and DDR to prevent the user from installing the wrong type of memory into the system.

DDR4 needs 20 percent less or just 1.2 volts, compared to DDR3 which requires 1.5 volts of electrical power to operate. DDR4 also supports

a new, deep power-down mode that allows the host device to go into standby without needing to refresh its memory. Deep power-down

mode is expected to reduce standby power consumption by 40 to 50 percent.

DDR4 Details

There are subtle dierences between DDR3 and DDR4 memory modules, as listed below.

Key notch dierence

The key notch on a DDR4 module is in a dierent location from the key notch on a DDR3 module. Both notches are on the insertion edge,

but the notch location on the DDR4 is slightly dierent, to prevent the module from being installed into an incompatible board or platform.

Figure 2. Notch dierence

Increased thickness

DDR4 modules are slightly thicker than DDR3, to accommodate more signal layers.

Figure 3. Thickness dierence

Curved edge

DDR4 modules feature a curved edge to help with insertion and alleviate stress on the PCB during memory installation.

Trusted Platform Module (TPM)

Overview

Trusted Platform Module, or TPM, is a security device that holds computer-generated keys for encryption. It is a hardware-based solution

that prevents hacking attempts to capture passwords, encryption keys, and other sensitive data. The security features provided by the

TPM are internally supported by:

• Hashing

• Random number generation

• Asymmetric key generation

• Asymmetric encryption/decryption

Each TPM has a unique signature initialized during the silicon manufacturing process that enhances the trust/security eectiveness. Every

TPM must have an owner before it can be utilized. The TPM user must be physically present to take ownership. After this procedure is

completed and the TPM has a unique owner, the TPM is activated.

Power status light: Indicates the power status.

Solid Amber – The computer is unable to boot to the operating system. This indicates that the power supply or another device in the

computer is failing.

Blinking Amber – The computer is unable to boot to the operating system. This indicates that the power supply is normal but another

device in the computer is failing or not installed properly.

NOTE: See the light patterns to determine the device that is failing.

O – Computer is in hibernation or turned o.

The power status light blinks amber along with beep codes indicating failures.

For example, the power status light blinks amber two times followed by a pause, and then blinks white three times followed by a pause. This

2,3 pattern continues until the computer is turned o indicating the Recovery image is not found.

The following table shows dierent light patterns and what they indicate:

LCD built in self test (BIST)

All-in-One (AIO) system supports LCD BIST similar to any other Dell systems that have BIST test implemented. It allows the user to isolate

the LCD during troubleshooting to determine which sub-system is at fault. The main dierence is the lack of an integrated keyboard scan

controller in the AIO. When BIST is initiated, an internal generated pattern from the LCD is emitted for user's observation. This pattern goes

by sequence through this pattern. Black-White-Red-Green-Blue or a White-Black-Red-Green-Blue where each pattern is emitted for 2-3

seconds. The following images display the pattern of the colors on the LCD:
